This is an attempt to implement a new `Value::LazyRecord` variant for
performance reasons.
`LazyRecord` is like a regular `Record`, but it's possible to access
individual columns without evaluating other columns. I've implemented
`LazyRecord` for the special `$nu` variable; accessing `$nu` is
relatively slow because of all the information in `scope`, and [`$nu`
accounts for about 2/3 of Nu's startup time on
Linux](https://github.com/nushell/nushell/issues/6677#issuecomment-1364618122).
### Benchmarks
I ran some benchmarks on my desktop (Linux, 12900K) and the results are
very pleasing.
Nu's time to start up and run a command (`cargo build --release;
hyperfine 'target/release/nu -c "echo \"Hello, world!\""' --shell=none
--warmup 10`) goes from **8.8ms to 3.2ms, about 2.8x faster**.
Tests are also much faster! Running `cargo nextest` (with our very slow
`proptest` tests disabled) goes from **7.2s to 4.4s (1.6x faster)**,
because most tests involve launching a new instance of Nu.
### Design (updated)
I've added a new `LazyRecord` trait and added a `Value` variant wrapping
those trait objects, much like `CustomValue`. `LazyRecord`
implementations must implement these 2 functions:
```rust
// All column names
fn column_names(&self) -> Vec<&'static str>;
// Get 1 specific column value
fn get_column_value(&self, column: &str) -> Result<Value, ShellError>;
```
### Serializability
`Value` variants must implement `Serializable` and `Deserializable`, which poses some problems because I want to use unserializable things like `EngineState` in `LazyRecord`s. To work around this, I basically lie to the type system:
1. Add `#[typetag::serde(tag = "type")]` to `LazyRecord` to make it serializable
2. Any unserializable fields in `LazyRecord` implementations get marked with `#[serde(skip)]`
3. At the point where a `LazyRecord` normally would get serialized and sent to a plugin, I instead collect it into a regular `Value::Record` (which can be serialized)
Previously the group check was only for the current users gid, now we
check against all the users groups.
# Description
Currently when using the `cd` command to enter a directory there was
only a check against the current user id, and exact current group id,
meaning if a directory had a group permission and that group wasn't the
users group it was effectively ignored.
The fix simply implements a check through all the users current groups.

# Description
This PR makes changes that allow underscores in numbers.
Example:
```nu
# allows underscores to be placed arbitrarily to enhance readability.
let pi = 3.1415_9265_3589_793
# works with integers
let num = 1_000_000_000_000
let fav_color = 0x68_9d_6a
```
I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give
better error messages. Similarly for `assert!(a != b)` and
`assert_ne!(a, b)`. Basically all instances were comparing primitives
(string slices or integers), so there is no loss of generality from
special-case macros,
I have also fixed a number of typos in comments, variable names, and a
few user-facing messages.
# Description
This PR allows the configuration of cursor shapes in nushell for each

vi_insert: block # block, underscore, line (block is the default)
vi_normal: underscore # block, underscore, line (underscore is the default)
}

Closes#6337 and #5366. Prior to this PR, when "shelling out" to cmd.exe
on Windows we were not trimming quotes correctly:
```bash
〉^echo "foo"
\"foo\"
```
After this change, we do:
```bash
〉^echo "foo"
foo
```
### Breaking Change
I ended up removing `dir` from the list of supported cmd.exe internal
commands as part of this PR.
For this PR, I extracted the argument-cleaning-and-expanding code from
`spawn_simple_command()` for reuse in `spawn_cmd_command()`. This means
that we now expand globs, which broke some tests for the `dir` cmd.exe
internal command.
I probably could have kept the tests working, but... tbh, I don't think
it's worth it. I don't want to make the `cmd.exe` functionality any more
complicated than it already is, and calling `dir` from Nu is always
going to be weird+hacky compared to `ls`.

# Description
In bash when a program crashes, it prints the reason for what happened:
```
$ ./division_by_zero
Floating point exception (core dumped)
$ ./segfault
Segmentation fault (core dumped)
```
Nushell always prints the same thing in this case:
```
> ./division_by_zero
nushell: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```
This PR adds more detailed error printing, like in bash:
```
> ./division_by_zero
Floating point exception: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```
I made this message format as an example:
```
Floating point exception: oops, process './division_by_zero' core dumped
```
Instead of `nushell:` it writes a meaningful message, but I can change
this format as per the suggestions.
I tested the change only on linux, but it should work on other unix
systems.

# Description
Closes#7514.
* For both `encode` and `decode`: add a special case allowing `utf16` as
a valid alias for `utf-16` (just as `utf-8` has `utf8`).
* For `encode` , make it an error when encodings_rs replaces characters
outside the given encoding with HTML entities
* For `encode` , add `-i`/`--ignore-errors` flag to bring back this
behaviour.
Note: `--ignore-errors` does NOT ignore the error for using a wrong
encoding label like `uft8`

I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time
For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`
When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.
Please let me know If I need to make any changes and I will be happy to
do it.
# User-Facing Changes

I've been using the new Criterion benchmarks and I noticed that they
take a _long_ time to build before the benchmark can run. Turns out
`cargo build` was building 3 separate benchmarking binaries with most of
Nu's functionality in each one.
As a simple temporary fix, I've moved all the benchmarks into a single
file so that we only build 1 binary.
### Future work
Would be nice to split the unrelated benchmarks out into modules, but
when I did that a separate binary still got built for each one. I
suspect Criterion's macros are doing something funny with module or file
names. I've left a FIXME in the code to investigate this further.
A small but easy optimization for `evaluate_repl()`: clone
`engine_state` 1x instead of 3x.
This reduces time spent in a simple REPL eval (`enter` key pressed with
no command text) by about 10%, as measured in
[Superluminal](https://superluminal.eu/).

# Description
Currently the implementation is different for Windows and Unix.
Thus certain operations will fail if the platform foreign line ending is
used:
example failing under windows
```
git show (git merge-base main HEAD)
```
Temporary cheat is to strip all `\r` and `\n` from the end. Proper
solution should trim them as correct patterns.
Also needed: test of behavior with both platform newline and
platform-foreign line endings

# User-Facing Changes

I have been recently going through some info logging in the cli and
noticed that there is too much info being printed to get a handle on
whats going on...
This is an attempt to do some minor logging clean up to print out "less
stuff",
in info logging mode mainly having to do with the prompt...
If someone really want to see what is going on they can very easily add
it
back in without too much trouble.
src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.
I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...
now that @rgwood has landed benches I want
to start experimenting with benchmarks related
to the parser.
For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...
Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...
Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...
It will also enable other crates going forward to
use BufferedReader. Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".
