Fix ls behaviour when directory is empty (#8439)
Prior to this PR, `ls` would return `nothing` in an empty directory.
After this PR, it returns an empty `List`. This makes the behaviour of
`ls` more consistent and easier to reason about (IMO).

This was prompted by a user noticing that `ls | where size == 0KB and
type == file` breaks when run in an empty directory:

```
  × Input type not supported.
   ╭─[entry #12:1:1]
 1 │ ls | where size == 0KB and type == file
   · ─┬   ──┬──
   ·  │     ╰── only list, binary, raw data or range input data is supported
   ·  ╰── input type: nothing
   ╰────
```

If people agree with this change, let's wait until after the 0.77
release so we have a bit more time to test it.

Box ShellError in Value::Error (#8375)
# Description

Our `ShellError` at the moment has a `std::mem::size_of<ShellError>` of
136 bytes (on AMD64). As a result `Value` directly storing the struct
also required 136 bytes (thanks to alignment requirements).

This change stores the `Value::Error` `ShellError` on the heap.

Pro:
- Value now needs just 80 bytes
- Should be 1 cacheline less (still at least 2 cachelines)

Con:
- More small heap allocations when dealing with `Value::Error`
  - More heap fragmentation
  - Potential for additional required memcopies

# Further code changes

Includes a small refactor of `try` due to a type mismatch in its large
match.

# User-Facing Changes

None for regular users.

Plugin authors may have to update their matches on `Value` if they use
`nu-protocol`

Needs benchmarking to see if there is a benefit in real world workloads.
**Update** small improvements in runtime for workloads with high volume
of values. Significant reduction in maximum resident set size, when many
values are held in memory.

Revert to notify v4 (#8367)
This reverts https://github.com/nushell/nushell/pull/8114 which upgraded
to `notify` (a file watching crate used by the `watch` command) v5.

`notify` v5 has several breaking changes and it's much harder to use. It
no longer includes debouncing of file system events, which I think is
essential functionality for `watch`. @WindSoilder was going to try
writing our own debouncing functionality but I don't think he had time
to finish it.

@WindSoilder Is it OK if we revert this for the 0.77 release (March 14)?
We can try again for 0.78

Fix 8244 -- store timestamps with nanosecond resolution (consistently) (#8337)
# Description

Fix for data ambiguity noted in #8244.

Basic change is to use nanosecond resolution for unix timestamps (stored
in type Int). Previously, a timestamp might have seconds, milliseconds
or nanoseconds, but it turned out there were overlaps in data ranges
between different resolutions, so there wasn't always a unique mapping
back to date/time.

Due to higher precision, the *range* of dates that timestamps can map to
is restricted. Unix timestamps with seconds resolution and 64 bit
storage can cover all dates from the Big Bang to eternity. Timestamps
with seconds resolution and 32 bit storage can only represent dates from
1901-12-13 through 2038-01-19. The nanoseconds resolution and 64 bit
storage used with this fix can represent dates from 1677-09-21T00:12:44
to 2262-04-11T23:47:16, something of a compromise.

# User-Facing Changes
_(List of all changes that impact the user experience here. This helps
us keep track of breaking changes.)_

## `<datetime> | into int`
Converts to nanosecond resolution
```rust
〉date now | into int
1678084730502126846
```
This is the number of non-leap nanoseconds after the unix epoch date:
1970-01-01T00:00:00+00:00.

Conversion fails for dates outside the supported range:
```rust
〉1492-10-12 | into int
Error: nu:🐚:incorrect_value

  × Incorrect value.
   ╭─[entry #51:1:1]
 1 │ 1492-10-12 | into int
   ·              ────┬───
   ·                  ╰── DateTime out of timestamp range 1677-09-21T00:12:43 and 2262-04-11T23:47:16
   ╰────


```

## `<int> | into datetime`
Can no longer fail or produce incorrect results for any 64-bit input:
```rust
〉0 | into datetime 
Thu, 01 Jan 1970 00:00:00 +0000 (53 years ago)
〉"7fffffffffffffff" | into int -r 16 | into datetime
Fri, 11 Apr 2262 23:47:16 +0000 (in 239 years)
〉("7fffffffffffffff" | into int -r 16) * -1 | into datetime
Tue, 21 Sep 1677 00:12:43 +0000 (345 years ago)
```

## `<date> | date to-record` and `<date> | date to-table`
Now both have a `nanosecond` field.  
```rust
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-record
╭────────────┬───────────╮
│ year       │ 2262      │

╰────────────┴───────────╯
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-table
╭───┬──────┬───────┬─────┬──────┬────────┬────────┬────────────┬──────────╮

╰───┴──────┴───────┴─────┴──────┴────────┴────────┴────────────┴──────────╯
```

This change was not mandated by the OP problem, but it is nice to be
able to see the nanosecond bits that were present in Nushell `date` type
all along.

Fix to json for SQLite databases (#8343)
Fixes #8341. 

The `CustomValue::to_json()` function is an odd duck; it defaults to
returning `null`, and no `CustomValue` implementations override it to do
anything useful. I forgot to implement `to_json()` for `SQLiteDatabase`,
so `open foo.db | to json` was returning `null`.

To fix this, I've removed `CustomValue::to_json()` and now `to json`
will collect a `CustomValue` into a regular `Value` before doing a JSON
conversion.

Document and critically review ShellError variants - Ep. 3 (#8340)
Continuation of #8229 and #8326

# Description

The `ShellError` enum at the moment is kind of messy. 

Many variants are basic tuple structs where you always have to reference
the implementation with its macro invocation to know which field serves
which purpose.
Furthermore we have both variants that are kind of redundant or either
overly broad to be useful for the user to match on or overly specific
with few uses.

So I set out to start fixing the lacking documentation and naming to
make it feasible to critically review the individual usages and fix
those.
Furthermore we can decide to join or split up variants that don't seem
to be fit for purpose.

changes Reqwest to Ureq. (#8320)
# Description

_(Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.)_

This pull request removes `Reqwest` and replaces it with `Ureq` to
remove some of our dependencies, giving us faster compile times as well
as smaller binaries. `Ureq` does not have an async runtime included so
we do not need build heavy dependencies such as `Tokio`. From older
tests I had the number of build units be reduced from `430 -> 392`.
The default of `Ureq` uses `Rustls` but it has been configured to
instead use `native_tls` which should work exactly the same as the `tls`
works now.
I removed `content-length` from the http commands as after refactoring i
did not see a reason to have it available, correct me if this is
something we should preserve.

In the medium, to long term, we should maybe consider changing to
`rustls` to have the same `tls` on all platforms.

Fix CPU usage info in sys (#8321)
Closes #8264. This PR does a few things to fix the `usage` column in
`sys.cpu`:

1. Sleep a while (~400ms) between calls to `sys.refresh_cpu()`, [as
required by
`sysinfo`](https://docs.rs/sysinfo/latest/sysinfo/trait.SystemExt.html#method.refresh_cpu)
2. Change `sys` to return a `LazyRecord` (so you can do things like `sys
| get host` instantly without waiting for CPU info)
3. Update our `sysinfo` dependency to [fix CPU usage calculations on
Linux](https://github.com/GuillaumeGomez/sysinfo/pull/946)

CPU usage is no longer always reported as zero:

Fix CPU frequency in sys output (#8275)
The `sys | get cpu.freq` column (supposed to contain the frequency for
each CPU core in megahertz) was incorrect for 2 reasons:
1. We weren't telling the `sysinfo` crate to refresh CPU frequency info
2. We were overwriting the values in the column with the systemwide
physical core count. Whoops!

Fix insecure + max-time arguments for HTTP commands. (#8266)
# Description

Follow up of https://github.com/nushell/nushell/pull/8255

Sorry about the max-time argument, I didn't pay attention to the
copy-paste. Regarding the insecure argument, the problem was before I
began to work on the refacto. My mistake was to not have tested this
argument.

cratification: Example support (#8231)
# Description

When the crate nu_cmd_lang crate was created last week example_test.rs
was copied over from nu_command
to nu_cmd_lang. By doing this there was a set of methods in
example_test.rs that existed in both crates...

This PR removes the redundancy by moving all of those duplicated methods
into the crate nu_test_support in a newly created file called
example_support.rs

Re-implement aliases (#8123)
# Description

This PR adds an alternative alias implementation. Old aliases still work
but you need to use `old-alias` instead of `alias`.

Instead of replacing spans in the original code and re-parsing, which
proved to be extremely error-prone and a constant source of panics, the
new implementation creates a new command that references the old
command. Consider the new alias defined as `alias ll = ls -l`. The
parser creates a new command called `ll` and remembers that it is
actually a `ls` command called with the `-l` flag. Then, when the parser
sees the `ll` command, it will translate it to `ls -l` and passes to it
any parameters that were passed to the call to `ll`. It works quite
similar to how known externals defined with `extern` are implemented.

The new alias implementation should work the same way as the old
aliases, including exporting from modules, referencing both known and
unknown externals. It seems to preserve custom completions and pipeline
metadata. It is quite robust in most cases but there are some rough
edges (see later).

Fixes https://github.com/nushell/nushell/issues/7648,
https://github.com/nushell/nushell/issues/8026,
https://github.com/nushell/nushell/issues/7512,
https://github.com/nushell/nushell/issues/5780,
https://github.com/nushell/nushell/issues/7754

No effect: https://github.com/nushell/nushell/issues/8122 (we might
revisit the completions code after this PR)

Should use custom command instead:
https://github.com/nushell/nushell/issues/6048

# User-Facing Changes

Since aliases are now basically commands, it has some new implications:

1. `alias spam = "spam"` (requires command call)
	* **workaround**: use `alias spam = echo "spam"`
2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than
once)
* **workaround**: use different name (commands also have this
limitation)
4. `alias ls = (ls | sort-by type name -i)`
* **workaround**: Use custom command. _The common issue with this is
that it is currently not easy to pass flags through custom commands and
command referencing itself will lead to stack overflow. Both of these
issues are meant to be addressed._
5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc.
* Should we treat the aliases as commands or should they be separated
from regular commands?
6. Needs better error message and syntax highlight for recursed alias
(`alias f = f`)
7. Can't create alias with the same name as existing command (`alias ls
= ls -a`)
	* Might be possible to add support for it (not 100% sure)
8. Standalone `alias` doesn't list aliases anymore
9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay
use` won't work)
	* TODO: Needs a better error message when attempting to do so

Simplify str trim command (#8205)
### What?

This change removes 3 flags (`--all`, `--both`, and `--format`) from
`str trim`. This is a net reduction of ~450 LoC and `str trim` no longer
depends on `fancy_regex`.

### Why?

I found these flags to be quite confusing when reviewing `str trim`
earlier today:

1. `--all` removes characters even if they're in the centre of the the
string.
- This is arguably not "trimming"! In all programming languages I'm
familiar with, trimming only affects the start and end of a string.
    - If someone needs to do this, `str replace` is more natural IMO
2. `--both` trims from the left and right
- Confusing and unnecessary given that this is also the default
behaviour
3. `--format` replaces multiple spaces with a single space, even in the
centre of the string
- Again, I don't think this falls under the scope of "trimming". IMO
`str replace` is a more natural fit

I believe that `str trim` is simpler and easier to understand after this
change.

### Before

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string
  -a, --all - trims all characters from both sides of the string *and* in the middle
  -b, --both - trims all characters from left and right side of the string
  -f, --format - trims spaces replacing multiple characters with singles in the middle
```

### After

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string

special-case ExternalStream in bytes starts-with (#8203)
# Description
`bytes starts-with` converts the input into a `Value` before running
.starts_with to find if the binary matches. This has two side effects:
it makes the code simpler, only dealing in whole values, and simplifying
a lot of input pipeline handling and value transforming it would
otherwise have to do. _Especially_ in the presence of a cell path to
drill into. It also makes buffers the entire input into memory, which
can take up a lot of memory when dealing with large files, especially if
you only want to check the first few bytes (like for a magic number).

This PR adds a special branch on PipelineData::ExternalStream with a
streaming version of starts_with.

# User-Facing Changes
Opening large files and running bytes starts-with on them will not take
a long time.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# Drawbacks
Streaming checking is more complicated, and there may be bugs. I tested
it with multiple chunks with string data and binary data and it seems to
work alright up to 8k and over bytes, though.

The existing `operate` method still exists because the way it handles
cell paths and values is complicated. This causes some "code
duplication", or at least some intent duplication, between the value
code and the streaming code. This might be worthwhile considering the
performance gains (approaching infinity on larger inputs).

Another thing to consider is that my ExternalStream branch considers
string data as valid input. The operate branch only parses Binary
values, so it would fail. `open` is kind of unpredictable on whether it
returns string data or binary data, even when passing `--raw`. I think
this can be a problem but not really one I'm trying to tackle in this
PR, so, it's worth considering.

pipe binary data to external commands (#8058)
Fixes #7615 

# Description

When calling external commands, we create a table from the pipeline data
to handle external commands expecting paginated input. When a binary
value is made into a table, we convert the vector of bytes representing
the binary bytes into a pretty formatted string. This results in the
pretty formatted string being sent to external commands instead of the
actual binary bytes. By checking whether the stdout of the call is being
redirected, we can decide whether to send the raw binary bytes or the
pretty formatted output when creating a table command.

# User-Facing Changes

When passing binary values to external commands, the external command
will receive the actual bytes instead of the pretty printed string. Use
cases that don't involve piping a binary value into an external command
are unchanged.

Dependency update: update notify version to v5 (#8114)
# Description

Relative: #8060

While investigating, I found we need to update notify, which is a good
step to remove some duplicate dependencies.

As title, here are some goods and bads after updating:

## Good
keep dependency up to date, and remove duplidate dependency(cfg-if,
winapi) in Cargo.lock.

## Bad
Introduce some breaking changes:
After updating to notify v5, I found that we have to remove `Rename`
events.

But I've testing under notify v4, and it doesn't work good if we running
the following command on MacOS:
```
touch a
mv a b
```
It fires file create event, but no file rename event. So `rename` event
is not really reliable, so I think it's ok for us to remove `Rename`
events.

The reason to remove `--debounce-ms` flag:
It's not provided by defualt file watcher, we can use
[PollWatcher](https://docs.rs/notify/latest/notify/poll/struct.PollWatcher.html),
but it scans filesystem, which is really expensive. So I just remove the
flag.

# User-Facing Changes

1. `--debounce-ms` flag is removed
2. no longer watch `Rename` event.

cp progress bar implementation (#8012)
# NOTE
Clean duplicate of #7825
Sorry about all the mess guys... I got confuse with GitHub and and ended
up mankind that mess.
This the same code I just cleaned the commits.

# Description
Progress bar implementation for the `cp` command. Now if the flag `-p`
or `--progress` is set, then the user will be able to see the progress
of the file or files being copy


![progressbar_cp01](https://user-images.githubusercontent.com/38369407/213899494-0f6a4aa9-ee82-48c3-a1f1-1816f3fc1d9c.jpg)

![progressbar_cp02](https://user-images.githubusercontent.com/38369407/213899497-2f9e6e8c-fdd9-400b-bd8d-c59899ae0368.jpg)

# User-Facing Changes
A new flag (`--progress` `-p`) was added to the `cp` command 
Examples:
```nu
cp -p test_file.txt test_folder_1\
cp -r -p test_folder\* test_folder_1\
cp -r -p -i test_folder\* test_folder_1\
```

## Notes 
- The progress bar uses `std::io::{Read, Write}` instead of
`std::fs::copy` to get the progress. that means that when the progress
bar is used the copy process might be a bit slower.
- Progress bar for symbolic links TBD: Since symbolic links are usually
very light I think is not worth it to duplicate the function
`copy_symlink` just to add a progress bar that will be so fast to the
point is not needed, but.. for consistency purposes we might need to
added it, In that case I would have to pass the variable `progress` by
parameter (to not duplicate code unnecessary). If I do that i would have
to pass the `progress` var to every function to respect `copy_impl: impl
Fn(PathBuf, PathBuf, Span)`. Please let me know if this is not clear :p

interrupt input command with Ctrl + C (#8159)
# Description

GH Issue: [#8074](https://github.com/nushell/nushell/issues/8074)

Adding SIGINT Ctrl + C functionality to *most* of the `input` command.
`input` with the flags `--suppress-output` and `--bytes-until` are
executed in raw mode which allows a ^C signal to be caught as it's
input, but an "optionless" call of `input` is using a standard
`read_line()` method that takes a ^C input and clears the buffer of any
data collected before the ^C. I'm more than happy to alter the
"optionless" call but putting it in raw mode hides the user input, so at
the moment that's unchanged.

# User-Facing Changes

Now ^C anywhere in the stdin stream will cause the command to SIGINT (as
long as the command isn't optionless), rather than being read in as part
of the input.
```
/home/rdevenney/projects/open_source/nushell〉input --suppress-output
Error: nu:🐚:io_error (link)

  × I/O error
  help: SIGINT
```

```
/home/rdevenney/projects/open_source/nushell〉input --bytes-until "a"
Error: nu:🐚:io_error (link)

  × I/O error
  help: SIGINT

```

As mentioned above, the default input behavior is the same.

2. Empty records are now correctly displayed if inside of another record
list or table:

3. Fixed inconsistent coloring of empty list placeholder inside of
lists/tables:
