I tackled some of the disabled `FIXME`/`#[ignore]` tests. Most were
straightforward to re-enable, and a few of them did not deserve to be
re-enabled.

I noticed that [it's pretty easy to name threads in
Rust](https://doc.rust-lang.org/std/thread/#naming-threads). We might as
well do this; it's a nice quality of life improvement when you're
profiling something and the developers took the time to give threads
names.
Also added/cleaned up some comments while I was in the area.

# Description
Add flags for filtering the output of `glob` by file type. I find myself
occasionally wanting to do this, and getting a file's
[file_type](https://docs.rs/wax/latest/wax/struct.WalkEntry.html#method.file_type)
is presumably fast to do as it doesn't have to go through the fallible
metadata method.
The design of the signature does concern me; it's not as readable as a
filter or "include" type list would be. They have to be filtered one by
one, which can be annoying if you only want files `-D -S`, or only want
folders `-F -S`, or only want symlinks `--butwhy?`. I considered
SyntaxShape::Keyword for this but I'll just defer to comments on this PR
if they pop up.
I'd also like to bring up performance since including these flags
technically incurs a `.filter` penalty on all glob calls, which could be
optimized out if we added a branch for the no-filters case. But in
reality I'd expect the file system to be the bottleneck and the flags to
be pretty branch predictor friendly, so eh
# User-Facing Changes
Three new flags when using `glob` and a slightly more cluttered help
page. No breaking changes, I hope.

This adds a `number` command that will enumerate the input, and add an

the item in the input stream, and `item` is the original value of the
item.

fix#7858
Once again we here 😞
~~I am thinking is there some files with not flat structure we could use
to test table -e?
I mean it is clear it was a while ago were we had to create at least
some tests.
Do you have anything in mind (or maybe commands which is consistent
across systems)?~~
Take care

# Description
Relative #7210
Improve doc to clarify current behavior.
To flatten all nested levels, we can use the following custom
command(maybe making it into our lib):
```
def flatten_all_nested [input_table: any] {
mut input = $input_table
mut flattened = ($input | flatten --all)
while $input != $flattened {
$input = $flattened
$flattened = ($input | flatten --all)
}
$flattened
}

Currently, if you run `do -i { sudo apt upgrade }`, stdin gets swallowed
and doesn't let you respond yes/no to the upgrade question. This PR
fixes that, but runs into https://github.com/nushell/nushell/issues/7205
so the tests fail.

Bumps [rayon](https://github.com/rayon-rs/rayon) from 1.5.3 to 1.6.1.

<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/rayon-rs/rayon/blob/master/RELEASES.md">rayon's
changelog</a>.</em></p>
<blockquote>
<h1>Release rayon 1.6.1 (2022-12-09)</h1>
<ul>
<li>Simplified <code>par_bridge</code> to only pull one item at a time
from the iterator,
without batching. Threads that are waiting for iterator items will now
block
appropriately rather than spinning CPU. (Thanks <a
href="https://github.com/njaard"><code>@njaard</code></a>!)</li>
<li>Added protection against recursion in <code>par_bridge</code>, so
iterators that also
invoke rayon will not cause mutex recursion deadlocks.</li>
</ul>
<h1>Release rayon-core 1.10.1 (2022-11-18)</h1>
<ul>
<li>Fixed a race condition with threads going to sleep while a broadcast
starts.</li>
</ul>
<h1>Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)</h1>
<ul>
<li>The minimum supported <code>rustc</code> is now 1.56.</li>
<li>The new <code>IndexedParallelIterator::fold_chunks</code> and
<code>fold_chunks_with</code> methods
work like <code>ParallelIterator::fold</code> and <code>fold_with</code>
with fixed-size chunks of
items. This may be useful for predictable batching performance, without
the
allocation overhead of
<code>IndexedParallelIterator::chunks</code>.</li>
<li>New "broadcast" methods run a given function on all
threads in the pool.
These run at a sort of reduced priority after each thread has exhausted
their
local work queue, but before they attempt work-stealing from other
threads.
<ul>
<li>The global <code>broadcast</code> function and
<code>ThreadPool::broadcast</code> method will
block until completion, returning a <code>Vec</code> of all return
values.</li>
<li>The global <code>spawn_broadcast</code> function and methods on
<code>ThreadPool</code>, <code>Scope</code>,
and <code>ScopeFifo</code> will run detached, without blocking the
current thread.</li>
</ul>
</li>
<li>Panicking methods now use <code>#[track_caller]</code> to report the
caller's location.</li>
<li>Fixed a truncated length in <code>vec::Drain</code> when given an
empty range.</li>
</ul>

# Updated description by @rgwood
This PR changes `fetch` to `http get` and `post` to `http post`. `fetch`
and `post` are now deprecated. [I surveyed people on
Discord](https://discord.com/channels/601130461678272522/601130461678272524/1065706282566307910)
and users strongly approved of this change.
# Original Description
This PR is related to #2741 and my first pull request in rust :)
Implemented a new http mod to better http support and alias `fetch` and
`post` commands to `http get` and `http post` respectively.
# User-Facing Changes
Users will be able to use HTTP method via http command, for example
``` shell
> http get "https://www.example.com"
<!doctype html>
<html>
...
```
# Description
This PR fixes the signature display when running `help commands`. Before
this PR, there were leading spaces in the signatures column. Now,
they're left aligned for a cleaner look.

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.

# User-Facing Changes
So the following command
```
1..100 | each { |i| sleep 400ms; $i} | save --raw -f output.txt
```
Will stream data to `output.txt`
But I'm note sure how to make a proper test for it, so I leave with no
new test cases..
Also rename from `string_binary_list_value_to_bytes ` to
`value_to_bytes` to accepts more Value type.

# Description
Refactor command: "to url" in: "to url query". Changed usage sentence.
Closes: #7495
# User-Facing Changes
Now we get a query string from a record or table by using command: "to
url query".
```
> help to url query
Convert record or table into query string applying percent-encoding.
Usage:
> to url query
Flags:
-h, --help - Display the help message for this command
Signatures:
<record> | to url query -> <string>
<table> | to url query -> <string>
Examples:
Outputs a query string representing the contents of this record
> { mode:normal userid:31415 } | to url query
Outputs a query string representing the contents of this 1-row table
> [[foo bar]; ["1" "2"]] | to url query
Outputs a query string representing the contents of this record
> {a:"AT&T", b: "AT T"} | to url query
```
# Tests + Formatting
Added this test:
```
Example {
description: "Outputs a query string representing the contents of this record",
example: r#"{a:"AT&T", b: "AT T"} | to url query"#,
result: Some(Value::test_string("a=AT%26T&b=AT+T")),
},
```
to ensure percent-encoding.
# After Submitting
If PR is accepted I'll open another PR on documentation to notify
changes on
[this.](https://github.com/nushell/nushell.github.io/blob/main/book/commands/to_url.md)
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.
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
This PR updates the base64 crate, which has changed significantly, so
all the base64 implementations had to be changed too. Tests pass. I hope
that's enough.
# User-Facing Changes
None, except added a new character encoding imap-mutf7 as mutf7.

# 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.
# User-Facing Changes
The error message only.

# 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`
