Make Command extend Shellbox's UnboxedCommand. Only a few MediaWiki-
specific features remain in the subclass.
Also add BoxedCommand abstraction and Shellbox client.
The Result alias didn't actually work, I just had to change the return
type hint.
Bug: T260330
Change-Id: Iff7428e4c5fe3959a5cda8e113f223caa0976fc1
Fixes executable paths with spaces in them, argument escapes,
and other strange behavior in Windows.
Also, fixes some shell tests on Windows. This is done by using
PHP scripts instead of native POSIX executables like "cat".
Behavior should be exactly the same on non-Windows servers.

Have ->restrict() overwrite any previous restrictions instead of adding
to the existing list. Multiple examples are provided on how this
function should be called going forward.
According to codesearch, all non-test uses of ->restrict() were already
expecting this behavior, passing values like:
Shell::RESTRICT_DEFAULT | Shell::NO_NETWORK
when trying to disable network access.
This is a breaking change, but IMO one that is going to fix more things
than it breaks.

Adds an intentionally failing test to demonstrate that calling
Command::restrict( Shell:RESTRICT_NONE ) is broken.

Anonymous pipe under Windows does not support asynchronous read and write[1],
and the default buffer is too small (~4K), the test will definitely block it.
Before T69870, anonymous pipe for Windows can no longer hold more than 4K of data.

This changeset implements T89432 and related tickets and is based on exploration
done at the Prague Hackathon. The goal is to identify tests in MediaWiki core
that can be run without having to install & configure MediaWiki and its dependencies,
and provide a way to execute these tests via the standard phpunit entry point,
allowing for faster development and integration with existing tooling like IDEs.
The initial set of tests that met these criteria were identified using the work Amir did in
I88822667693d9e00ac3d4639c87bc24e5083e5e8. These tests were then moved into a new subdirectory
under phpunit/ and organized into a separate test suite. The environment for this suite
is set up via a PHPUnit bootstrap file without a custom entry point.
You can execute these tests by running:
$ vendor/bin/phpunit -d memory_limit=512M -c tests/phpunit/unit-tests.xml

If the write buffer for a file descriptor is empty, don't try to write
to it. Just close it and continue on.

Right now they're treated as empty strings, however
this doesn't allow skipping parameters in the middle like
$params = [
'foo',
$x ? '--bar' : null,
'--baz',
];
In some cases this matters, e.g. `ls` works while `ls ''` doesn't.
Also, fix spacing problems the new tests uncovered:
* Extra space when using params()
* Missing space when combining params() and unsafeParams()

This function has gotten so unwieldy that a helper was
introduced. Instead, here's this class that makes
shelling out easier and more readable.
Example usage:
$result = Shell::command( 'shell command' )
->environment( [ 'ENVIRONMENT_VARIABLE' => 'VALUE' ] )
->limits( [ 'time' => 300 ] )
->execute();
$exitCode = $result->getExitCode();
$output = $result->getStdout();
This is a minimal change, so lots of stuff remains
unrefactored - I'd rather limit the scope of this commit.
A future improvement could be an ability to get stderr
separately from stdout.
Caveat: execution errors (proc_open is disabled/returned error) now
throw errors instead of returning a status code. wfShellExec() still
emulates this behavior though.

<legoktm> MaxSem: so you should continue working on your patch and I'll
probably refactor on top of it later after its merged :P
