Don't panic if the other end of std{out,err} is closed (#4179)
* fix #4161

println! and friends will panic on BrokenPipe. The solution is to use
writeln! instead, and ignore the error (or do we want to do something else?)

* test that nu doesn't panic in case of BrokenPipe error

* fixup! test that nu doesn't panic in case of BrokenPipe error

* make do_not_panic_if_broken_pipe only run on UNIX systems

Sanitize arguments to external commands a bit better (#4157)
* fix #4140

We are passing commands into a shell underneath but we were not
escaping arguments correctly. This new version of the code also takes
into consideration the ";" and "&" characters, which have special
meaning in shells.

We would probably benefit from a more robust way to join arguments to
shell programs. Python's stdlib has shlex.join, and perhaps we can
take that implementation as a reference.

* clean up escaping of posix shell args

I believe the right place to do escaping of arguments was in the
spawn_sh_command function. Note that this change prevents things like:

^echo "$(ls)"

from executing the ls command. Instead, this will just print

$(ls)

The regex has been taken from the python stdlib implementation of shlex.quote

* fix non-literal parameters and single quotes

* address clippy's comments

* fixup! address clippy's comments

Create errors from tables. (#3986)
```
> [
  [          msg,                 labels,                      span];
  ["The message", "Helpful message here", ([[start, end]; [0, 141]])]
] | error make

error: The message
  ┌─ shell:1:1
  │
1 │ ╭ [
2 │ │   [          msg,                 labels,                      span];
3 │ │   ["The message", "Helpful message here", ([[start, end]; [0, 141]])]
  │ ╰─────────────────────────────────────────────────────────────────────^ Helpful message here
```

Adding a more flexible approach for creating error values. One use case, for instance is the
idea of a test framework. A failed assertion instead of printing to the screen it could create
tables with more details of the failed assertion and pass it to this command for making a full
fledge error that Nu can show. This can (and should) be extended for capturing error values as well
in the pipeline. One could also use it for inspection.

For example: `.... | error inspect { # inspection here }`

or "error handling" as well, like so: `.... | error capture { fix here }`

However, we start here only with `error make` that creates an error value for you with limited support for the time being.

nu-path crate refactor (#3730)
* Resolve rebase artifacts

* Remove leftover dependencies on removed feature

* Remove unnecessary 'pub'

* Start taking notes and fooling around

* Split canonicalize to two versions; Add TODOs

One that takes `relative_to` and one that doesn't.
More TODO notes.

* Merge absolutize to and rename resolve_dots

* Add custom absolutize fn and use it in path expand

* Convert a couple of dunce::canonicalize to ours

* Update nu-path description

* Replace all canonicalize with nu-path version

* Remove leftover dunce dependencies

* Fix broken autocd with trailing slash

Trailing slash is preserved *only* in paths that do not contain "." or
"..". This should be fixed in the future to cover all paths but for now
it at least covers basic cases.

* Use dunce::canonicalize for canonicalizing

* Alow cd recovery from non-existent cwd

* Disable removed canonicalize functionality tests

Remove unused import

* Break down nu-path into separate modules

* Remove unused public imports

* Remove abundant cow mapping

* Fix clippy warning

* Reformulate old canonicalize tests to expand_path

They wouldn't work with the new canonicalize.

* Canonicalize also ~ and ndots; Unify path joining

Also, add doc comments in nu_path::expansions.

* Add comment

* Avoid expanding ndots if path is not valid UTF-8

With this change, no lossy path->string conversion should happen in the
nu-path crate.

* Fmt

* Slight expand_tilde refactor; Add doc comments

* Start nu-path integration tests

* Add tests TODO

* Fix docstring typo

* Fix some doc strings

* Add README for nu-path crate

* Add a couple of canonicalize tests

* Add nu-path integration tests

* Add trim trailing slashes tests

* Update nu-path dependency

* Remove unused import

* Regenerate lockfile

Allow environment variables to be hidden (#3950)
* Allow environment variables to be hidden

This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.

Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.

This is a workaround for issues like #3920.

Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.

One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.

An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.

* Remove unused import

* Allow all primitives to be convert to strings

Support equals sign in shorthand environment variable values (#3869)
Some environment variables, such as `RUST_LOG` include equals signs. Nushell
should support this in the shorthand environment variable syntax so that
developers using these variables can control them easily. We accomplish this by
swapping `std::str::split` for `std::str::splitn`, which ensures that we only
consider the first equals sign in the string instead of all of them, which we
did previously.

Closes #3867

Add the load-env command (#3484)
* Add the load-env command

load-env can be used to add environment variables dynamically via an
InputStream. This allows developers to create tools that output environment
variables as key-value pairs, then have the user load those variables in using
load-env. This supplants most of the need for an `eval` command, which is
mostly used in POSIX envs for setting env vars.

Fixes #3481
