Adds multi-file support to IDE support (#8857)
# Description

This adds multi-file support to the in-progress IDE support. The main
new features are a `-I` flag that allows you to add a new source search
path when starting up the nu binary, and fixes for the current IDE
support to support spans in other files.

This needs accompanying fixes to the vscode/lsp implementation to pass
along the project directory via `-I`.

UPDATE: Marking this draft until we have a means to test this.

Move CLI related commands to nu-cli (#8832)
# Description

Part of the larger cratification effort.

Moves all `reedline` or shell line editor specific commands to `nu-cli`.

## From `nu-cmd-lang`:
- `commandline`
- This shouldn't have moved there. Doesn't directly depend on reedline
but assumes parts in the engine state that are specific to the use of
reedline or a REPL

## From `nu-command`:
- `keybindings` and subcommands
  - `keybindings default`
  - `keybindings list`
  - `keybindings listen`
    - very `reedline` specific
- `history`
  - needs `reedline`
- `history session`

## internal use
Instead of having a separate `create_default_context()` that calls
`nu-command`'s `create_default_context()`, I added a `add_cli_context()`
that updates an `EngineState`


# User-Facing Changes

None

## Build time comparison

`cargo build --timings` from a `cargo clean --profile dev`

### total
main: 64 secs
this: 59 secs

### `nu-command` build time

branch | total| codegen | fraction  
---|---|---|---
main | 14.0s | 6.2s | (44%)
this | 12.5s | 5.5s | (44%)

`nu-cli` depends on `nu-command` at the moment.
Thus it is built during the code-gen phase of `nu-command` (on 16
virtual cores)

# Tests + Formatting

I removed the `test_example()` facilities for now as we had not run any
of the commands in an `Example` test and importing the right context for
those tests seemed more of a hassle than the duplicated
`test_examples()` implementations in `nu-cmd-lang` and `nu-command`

remove nu_cli crate dependency from nu_std (#8807)
now nu_std only depends on nu_parser, nu_protocol and miette
and removes the nu_cli dependency

this enables developers moving forward to come along and implement their
own CLI's without having to pull in a redundant nu-cli which will not be
needed for them.

I did this by moving report_error into nu_protocol
which nu_std already has a dependency on anyway....

Add IDE support (#8745)
# Description

This adds a set of new flags on the `nu` binary intended for use in
IDEs. Here is the set of supported functionality so far:

* goto-def - go to the definition of a variable or custom command
* type hints - see the inferred type of variables
* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position

# User-Facing Changes

No changes to the REPL experience. This only impacts the IDE scenario.

Remove -t/--threads flag from nu (#8686)
### What?

This PR removes the `--threads` flag from nu.exe:


![image](https://user-images.githubusercontent.com/26268125/229021408-bf78ce64-11f7-4354-a410-ed905b96bb5a.png)

### Why?

Darren added a `--threads` flag to `par-each` in
https://github.com/nushell/nushell/pull/8679, so it no longer respects
the global `--threads` flag. Now the only place `rayon` is used is [the
`table`
renderer](3db0aed9f7/crates/nu-command/src/viewers/table.rs (L15)).

I don't think anyone will actually want to specify the number of threads
used in `table`, and it would be confusing to leave this flag around
when it no longer does anything useful.

### Notes

Relevant `rayon` docs:

binary, looks like:

```nushell
let-env config = {
  # ...
  hooks: {
    command_not_found: {
      |cmd_name| (
        try {
          let pkgs = (pkgfile --binaries --verbose $cmd_name)
          (
            $"(ansi $env.config.color_config.shape_external)($cmd_name)(ansi reset) " +
            $"may be found in the following packages:\n($pkgs)"
          )
        } catch {
          null

FEATURE: add the startup time to $nu (#8353)
# Description
in https://github.com/nushell/nushell/issues/8311 and the discord
server, the idea of moving the default banner from the `rust` source to
the `nushell` standar library has emerged 😋

however, in order to do this, one need to have access to all the
variables used in the default banner => all of them are accessible
because known constants, except for the startup time of the shell, which
is not anywhere in the shell...

#### this PR adds exactly this, i.e. the new `startup_time` to the `$nu`
variable, which is computed to have the exact same value as the value
shown in the banner.

## the changes
in order to achieve this, i had to
- add `startup_time` as an `i64` to the `EngineState` => this is, to the
best of my knowledge, the easiest way to pass such an information around
down to where the banner startup time is computed and where the `$nu`
variable is evaluated
- add `startup-time` to the `$nu` variable and use the `EngineState`
getter for `startup_time` to show it as a `Value::Duration`
- pass `engine_state` as a `&mut`able argument from `main.rs` down to
`repl.rs` to allow the setter to change the value of `startup_time` =>
without this, the value would not change and would show `-1ns` as the
default value...
- the value of the startup time is computed in `evaluate_repl` in
`repl.rs`, only once at the beginning, and the same value is used in the
default banner 👌

# User-Facing Changes
one can now access to the same time as shown in the default banner with
```bash
$nu.startup-time
```

Add is-interactive and is-login to NuVariable and allow running scripts with -i (#8306)
Add two rows in `$nu`, `$nu.is-interactive` and `$nu.is-login`, which
are true when nu is run in interactive and login mode respectively.

The `-i` flag now behaves a bit more like that of bash's, where the any
provided command or file is run without REPL but in "interactive mode".
This should entail sourcing interactive-mode config files, but since we
are planning on overhauling the config system soon, I'm holding off on
that. For now, all `-i` does is set `$nu.is-interactive` to be true.

About testing, I can't seem to find where cli-args get tested, so I
haven't written any new tests for this. Also I don't think there are any
docs that need updating. However if I'm wrong please tell me.

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

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

- `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.

add some startup performance metrics (#7851)
# Description

This PR changes the old performance logging with `Instant` timers. I'm
not sure if this is the best way to do it but it does help reveal where
time is being spent on startup. This is what it looks like when you
launch nushell with `cargo run -- --log-level info`. I'm using the
`info` log level exclusively for performance monitoring at this point.

Progress bar Implementation (#7661)
# Description

_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_

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 

![nu_pb01](https://user-images.githubusercontent.com/38369407/210298647-07ee55ea-e751-41b1-a84d-f72ec1f6e9e5.jpg)
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.

![nu_pb02](https://user-images.githubusercontent.com/38369407/210298698-1ef65f51-40cc-4481-83de-309cbd1049cb.jpg)

move BufferedReader out of nu-command (#7697)
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".

Reorder flags in nu --help (#7672)
The ordering of flags in `nu --help` was a bit of a mess; I think it
grew organically over time. Related commands (like
`--config`/`--env-config`/`--plugin-config`) weren't grouped together,
common flags weren't near the top, and we weren't following alphabetical
ordering.

### Before

```bash
Flags:
  -h, --help - Display the help message for this command
  --stdin - redirect standard input to a command (with `-c`) or a script file
  -l, --login - start as a login shell
  -i, --interactive - start as an interactive shell
  -v, --version - print the version
  --testbin <String> - run internal test binary
  -c, --commands <String> - run the given commands and then exit
  --config <String> - start with an alternate config file
  --env-config <String> - start with an alternate environment config file
  --log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
  --log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
  -e, --execute <String> - run the given commands and then enter an interactive shell
  -t, --threads <Int> - threads to use for parallel commands
  -m, --table-mode <String> - the table mode to use. rounded is default.
  --plugin-config <String> - start with an alternate plugin signature file
```

### After

```bash
Flags:
  -h, --help - Display the help message for this command
  -c, --commands <String> - run the given commands and then exit
  -e, --execute <String> - run the given commands and then enter an interactive shell
  -i, --interactive - start as an interactive shell
  -l, --login - start as a login shell
  -m, --table-mode <String> - the table mode to use. rounded is default.
  -t, --threads <Int> - threads to use for parallel commands
  -v, --version - print the version
  --config <String> - start with an alternate config file
  --env-config <String> - start with an alternate environment config file
  --plugin-config <String> - start with an alternate plugin signature file
  --log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
  --log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
  --stdin - redirect standard input to a command (with `-c`) or a script file
  --testbin <String> - run internal test binary
```

The new ordering:

1. Groups commands with short flags together, sorted alphabetically by
short flag
1. Groups commands with only long flags together, sorted alphabetically
(with the exception of `--plugin-config` so we can keep related flags
together)

Conveniently, this puts the very commonly used `-c` at the top and the
very rarely used `--testbin` at the bottom.

Clarify --stdin flag (#7541)
Just change the description of the `--stdin` flag as shown in `nu
--help`:

"redirect the stdin" -> "redirect standard input to a command (with
`-c`) or a script file"

The old description was a little too terse and I had to look in the code
to see what it was doing.

Improve empty pipelines (#7383)
# Description

This fix changes pipelines to allow them to actually be empty. Mapping
over empty pipelines gives empty pipelines. Empty pipelines immediately
return `None` when iterated.

This removes a some of where `Span::new(0, 0)` was coming from, though
there are other cases where we still use it.

Make external command substitution works friendly(like fish shell, trailing ending newlines) (#7156)
# Description

As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.

And if the command is executed directly like: `cat tmp`, the result
won't change.

Fixes: #6816
Fixes: #3980


Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.

If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Add plugin CLI argument (#6064)
* Add plugin CLI argument

While working on supporting CustomValues in Plugins I stumbled upon the
test utilities defined in [nu-test-support][nu-test-support]
and thought these will come in handy, but they end up being outdated.
They haven't been used or since engine-q's was merged, so they are
currently using the old way engine-q handled plugins, where it would
just look into a specific folder for plugins and call them without
signatures or registration. While fixing that I realized that there is
currently no way to tell nushell to load and save signatures into a
specific path, and so those integration tests could end up potentially
conflicting with each other and with the local plugins the person
running them is using.

So this adds a new CLI argument to specify where to store and load
plugin signatures from

I am not super sure of the way I implemented this, mainly
I was a bit confused about the distinction between
[src/config_files.rs][src/config_files.rs] and
[crates/nu-cli/src/config_files.rs][crates/nu-cli/src/config_files.rs].
Should I be moving the plugin loading function from the `nu-cli` one to
the root one?

[nu-test-support]: 9d0be7d96f/crates/nu-test-support/src/macros.rs (L106)
[src/config_files.rs]: 9d0be7d96f/src/config_files.rs

Support binary data to stdin of run-external (#4984)
* Add test for passing binary data through externals

This change adds an ignored test to confirm that binary data is passed
correctly between externals to be enabled in a later commit along with
the fix.

To assist in platform agnostic testing of binary data a couple of
additional testbins were added to allow testing on `Value::Binary` inside
`ExternalStream`.

* Support binary data to stdin of run-external

Prior to this change, any pipeline producing binary data (not detected
as string) then feed into an external would be ignored due to
run-external only supporting `Value::String` on stdin.

This change adds binary stdin support for externals allowing something
like this for example:

  〉^cat /dev/urandom | ^head -c 1MiB | ^pv -b | ignore
  1.00MiB

This would previously output `0.00 B [0.00 B/s]` due to the data not
being pushed to stdin at each stage.
