https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants

Should unblock https://github.com/nushell/nushell/pull/9678

### Example:
```nushell
module spam {
    export module eggs {
        export module bacon {
            export const viking = 'eats'
        }
    }
}

use spam 
print $spam.eggs.bacon.viking  # prints 'eats'

use spam [eggs]
print $eggs.bacon.viking  # prints 'eats'

use spam eggs bacon viking
print $viking  # prints 'eats'
```

### Limitation 1:

Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ]  # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ]  # obviously wrong name for a constant, but doesn't work also for commands
```

Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]

print $bacon.viking  # prints 'eats'
```

I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.

### Limitation 2:

`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

Sort entries in scope commands; Fix usage of externs (#10039)
# Description

* All output of `scope` commands is sorted by the "name" column. (`scope
externs` and some other commands had entries in a weird/random order)
* The output of `scope externs` does not have extra newlines (that was
due to wrong usage creation of known externals)

test: clear parent envs to prevent leakage to tests (#9976)

Auto-expand table based on terminal width (#9934)
# Description

This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.

This sets the default config value in both the Rust and the default
nushell config.

To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.

Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

Add tests for script subcommands (#9933)
# Description

Add a few tests to ensure that you can add subcommands to scripts. We've
supported this for a long time, though I'm not sure if anyone has
actually tried it. As we weren't testing the support, this PR adds a few
tests to ensure it stays working.

Example script subcommand:

```
def "main addten" [x: int] {
  print ($x + 10)
}
```

then call it with:

```
> nu ./script.nu addten 5
```

allow print to take data as input again (#9823)
related to
https://discord.com/channels/601130461678272522/601130461678272524/1134079115134251129

# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of 
```nushell
print "foo"
```

this PR enables the `any -> nothing` input / output type to allow this
again.

i've double checked and `print` is essentially the following snippet
```rust
        if !args.is_empty() {
            for arg in args {
                arg.into_pipeline_data()
                    .print(engine_state, stack, no_newline, to_stderr)?;
            }
        } else if !input.is_nothing() {
            input.print(engine_state, stack, no_newline, to_stderr)?;
        }
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`

# User-Facing Changes
```nushell
"foo" | print
```
works again

remove let-env, focus on mutating $env (#9574)
# Description

For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.

So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.

Before:

```
let-env FOO = "BAR"
```

Now:

```
$env.FOO = "BAR"
```

It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

Better error message if env var is used as var (#9522)
# Description

This PR improves the error message if an environment variable (that's
visible before the parser begins) is used in the form of `$PATH` instead
of `$env.PATH`.

Before:

```
Error: nu::parser::variable_not_found

  × Variable not found.
   ╭─[entry #31:1:1]
 1 │ echo $PATH
   ·      ──┬──
   ·        ╰── variable not found.
   ╰────
```

After:

```
Error: nu::parser::env_var_not_var

  × Use $env.PATH instead of $PATH.
   ╭─[entry #1:1:1]
 1 │ echo $PATH
   ·      ──┬──
   ·        ╰── use $env.PATH instead of $PATH
   ╰────

split $nu variable into scope commands and simpler $nu (#9487)
# Description

This splits off `scope` from `$nu`, creating a set of `scope` commands
for the various types of scope you might be interested in.

This also simplifies the `$nu` variable a bit.

# User-Facing Changes

This changes `$nu` to be a bit simpler and introduces a set of `scope`
subcommands.

Use pretty_assertions in the root crate (#8818)
# Description

This PR is just a minor development improvement. While working on
another feature, I noticed that the root crate lists the super useful
`pretty_assertions` in the root crate but doesn't use it in most tests.
With this change `pretty_assertions::assert_eq!` is used instead of
`core::assert_eq!` for better diffs when debugging the tests.

I thought of adding the dependency to other crates but I decided not to
since I didn't want a huge disruptive PR :)

Revert "Allow NU_LIBS_DIR and friends to be const" (#8501)
Reverts nushell/nushell#8310

In anticipation that we may want to revert this PR. I'm starting the
process because of this issue.

This stopped working
```
let-env NU_LIB_DIRS = [
    ($nu.config-path | path dirname | path join 'scripts')
    'C:\Users\username\source\repos\forks\nu_scripts'
    ($nu.config-path | path dirname)
]
```
You have to do this now instead.
```
const NU_LIB_DIRS = [
    'C:\Users\username\AppData\Roaming\nushell\scripts'
    'C:\Users\username\source\repos\forks\nu_scripts'
    'C:\Users\username\AppData\Roaming\nushell'
]
```

In talking with @kubouch, he was saying that the `let-env` version
should keep working. Hopefully it's a small change.

Restrict closure expression to be something like {|| ...} (#8290)
# Description

As title, closes: #7921 closes: #8273

# User-Facing Changes

when define a closure without pipe, nushell will raise error for now:
```
❯ let x = {ss ss}
Error: nu::parser::closure_missing_pipe

  × Missing || inside closure
   ╭─[entry #2:1:1]
 1 │ let x = {ss ss}
   ·         ───┬───
   ·            ╰── Parsing as a closure, but || is missing
   ╰────
  help: Try add || to the beginning of closure
```

`any`, `each`, `all`, `where` command accepts closure, it forces user
input closure like `{||`, or parse error will returned.
```
❯ {major:2, minor:1, patch:4} | values | each { into string }
Error: nu::parser::closure_missing_pipe

  × Missing || inside closure
   ╭─[entry #4:1:1]
 1 │ {major:2, minor:1, patch:4} | values | each { into string }
   ·                                             ───────┬───────
   ·                                                    ╰── Parsing as a closure, but || is missing
   ╰────
  help: Try add || to the beginning of closure
```

`with-env`, `do`, `def`, `try` are special, they still remain the same,
although it says that it accepts a closure, but they don't need to be
written like `{||`, it's more likely a block but can capture variable
outside of scope:
```
❯ def test [input] { echo [0 1 2] | do { do { echo $input } } }; test aaa
aaa
```

Just realize that It's a big breaking change, we need to update config
and scripts...

Allow NU_LIBS_DIR and friends to be const (#8310)
# Description

Allow NU_LIBS_DIR and friends to be const they can be updated within the
same parse pass. This will allow us to remove having multiple config
files eventually.

Small implementation detail: I've changed `call.parser_info` to a
hashmap with string keys, so the information can have names rather than
indices, and we don't have to worry too much about the order in which we
put things into it.

Closes https://github.com/nushell/nushell/issues/8422

# User-Facing Changes

In a single file, users can now do stuff like
```
const NU_LIBS_DIR = ['/some/path/here']
source script.nu
```
and the source statement will use the value of NU_LIBS_DIR declared the
line before.

Currently, if there is no `NU_LIBS_DIR` const, then we fallback to using
the value of the `NU_LIBS_DIR` env-var, so there are no breaking changes
(unless someone named a const NU_LIBS_DIR for some reason).

Disable pipeline echo (#8292)
# Description

Change behavior of block evaluation to not print result of intermediate
commands.
Previously result of every but last pipeline in a block was printed to
stdout, and last one was returned

![image](https://user-images.githubusercontent.com/17511668/222550110-3f62fbed-432c-4b46-b9b1-4cb45a1f893e.png)
With this change results of intermediate pipelines are discarded after
they finish and the last one is returned as before:

![image](https://user-images.githubusercontent.com/17511668/222550346-f1e74f80-f6b6-4aa3-98d6-888ea4cb4915.png)
Now one should use `print` explicitly to print something to stdout

![image](https://user-images.githubusercontent.com/17511668/222923955-fda0d77b-41b4-4f91-a80f-12b0a1880c05.png)

**Note, that this behavior is not limited to functions!** The scope of
this change are all blocks. All of the below are executed as blocks and
thus exibited this behavior in the same way:

![image](https://user-images.githubusercontent.com/17511668/222924062-342c15de-4273-4bf5-8b39-fe6e3aa96076.png)

With this change outputs for all types of blocks are cleaned:

Escape will now escape paths with '=' in them (#8485)
# Description

Fixes the issue where there is no way to escape `FOO=BAR` in a way that
treats it as a file path/executable name. Previously `^FOO=BAR` would be
handled as an environment shorthand. Now, environment shorthands are not
allowed to start with `^`. To create an environment shorthand value that
uses `^` as the first character of the environment variable name, use
quotes, eg `"^FOO"=BAR`

updates a test to use testbin versus external echo (#8387)
# Description

In the past, I've seen this test
`takes_rows_of_nu_value_strings_and_pipes_it_to_stdin_of_external` fail
more than a few times. My only guess was that running external commands
in a cross-platform way can be tricky. This is the main reason we have
some `--testbin` commands, to avoid this situation. With that in mind,
this removes the `^echo` command from this one test and replaces it with
`nu --testbin cococo`, which I believe is our equivalent of echo.

Please comment below if you think this is the wrong strategy. There are
other `^echo` tests but I'm not sure if we can change all of them.

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.

Update the command 'version'. (#8312)
# Description

No real changes, just some cleanup while I was looking at the code of
the command.

# User-Facing Changes

Remove the attribute 'pkg_version', since it's already exposed through
'version'.

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

remove links to ShellError and ParseError docs - #8167 (#8193)
# Description

issue #8167

Remove the `(link)` to the docs for `ShellError` and `ParseError`. As
per discussion on the issue, the nu-parser version didn't update on the
docs causing deadlinks for those errors, which brought the usefullness
of these links into question and it was decided to remove all of them
that `derive(diagnostic)`.

# User-Facing Changes

`table` command now displays empty records and lists like a table with
text and correctly displays empty records inside tables and lists.

New behavior of displaying empty lists and records can be disabled using
`table.show_empty` config option.
