Summary:
This change fixes the command `arc look remotes` for PHP 8.1.
Without this change, the null value bubbles up to PhutilUTF8StringTruncator, reaching a strlen().
This control probably does not need to be done at this low level inside PhutilUTF8StringTruncator,
but it is right to be at this high level from the caller in ArcanistRefView.
Closes T15368
Test Plan:
- run "arc look remotes"
- still works in "old PHP" like 7.4
- start to work in recent PHP 8.1+

`array_fuse` in Arcanist is a wrapper for calling `array_combine($list, $list)`.
The latter doesn't accept passing `null` in PHP 8.2.
Going to `/conduit/method/project.create/`, entering a `name` but nothing as `members` (so we pass `null`), and calling this method, an exception is thrown.

Summary:
Mercurial 6.4 was recently released and showing up in package managers. With
the update to 6.4 using `arc land` would result in an exception indicating that
`expandpath` function does not exist.
The `ui.expandpath` function was deprecated in 5.8 and now removed in 6.4. The
functionality has been moved to `utils.urlutil.get_` functions (they are split
between getting pull, push, and clone paths).
This updates the script to try `utils.urlutil.get_clone_path` function if the
`ui.expandpath` function is not present.

Summary:
For some reason it may happen that a specific command line argument receives a null argument
from PHP, instead of just an empty string.
Nowadays, this null value probably breaks almost whatever GNU/Linux or FreeBSD or Microsoft Windows
etc. implementations since everyone expect to receive a string.
This used to work in the past since functions like strpos() or strlen() accepted null, but not
anymore. This generate a deprecation warning since PHP 8.1, that is elevated as exception from
Phabricator/Phorge and breaking features.
Without getting into implementation logics (which doesn't make sense to fix all of them) the
calling function should just be kind. So we normalize nonsense null values to an empty string.
Note: this was the expected behavior prior to PHP 8.1.
Now we do that normalization explicitly, in this early point.
After this fix, also T15368 should probably be fixed.

Summary:
Entering a malformed string (like `"pHoRgE rOcKs!!"`) into the "Raw Diff" field, Arcanist's `tryMatchHeader()` function is first called in `$ok = $this->tryMatchHeader($patterns, $line, $match)` with a non-null `$line` value (the first line entered in the "Raw Diff" field) being passed.
Afterwards, `tryMatchHeader()` is called for a second time after assigning `$line = $this->nextLineThatLooksLikeDiffStart()`.
This time `$line` is null and a RuntimeException is thrown, as `tryMatchHeader()` calls `preg_match()` which does not accept passing null as the $subject string parameter in PHP 8.1.
Thus add a `phutil_nonempty_string()` check if the `$subject` parameter (in this case, `$line`) is a non-empty string.
Arcanist's `tryMatchHeader()` function is not called outside of the file in which it is defined.
Thus catch the exception in the second call to `tryMatchHeader()` and not in the code of the `tryMatchHeader()` function itself.
Closes T15338

Summary:
Ref T13666. Currently, "PhabricatorRepository->newConduitFuture()" sometimes returns a real "ConduitFuture" (when repository clustering is configured) and sometimes returns a degenerate "ImmediateFuture" (when repository clustering is not configured).
To populate the "ImmediateFuture", the Conduit method is called inline without any special exception handling. This means that the two pathways have significantly different exception behavior:
- On the "ImmediateFuture" pathway, the "newConduitFuture()" method itself may raise an exception related to resolving the call (e.g., invalid parameters).
- On the "ConduitFuture" pathway, exceptions are raised only once the future is "resolve()"'d.
The second behavior is the correct behavior (and the primary behavior of upstream test environments, since all my stuff and the Phacility stuff is clustered).
Prepare to put both pathways on the second behavior by introducing a "MethodCallFuture", which can move the `$conduit_call->execute()` call (and thus its exception handling) to future resolution time.

`arc liberate` has been broken for a while because the `log` function attempts to call `fwrite` (whose third argument is an integer length) instead of `fprintf`. I think maybe PHP 5 was more lenient about this? Anyway, this bug makes other development somewhat tricky.
The arcanist source in general seems to be split between `fwrite(STDERR, $message."\n")` and `fprintf(STDERR, "%\n", $message)`; I decided to go with the latter.

- Grepped for callsites.
- Ran `arc patch --trace` in a Git working copy and saw the updated "git apply" in the trace output.
- Used this test script (changing the method and the command invoked) to confirm that success and error behavior is identical in "resolve()" and "execute()", except that "execute()" now emits a deprecation warning:
```
<?php
require_once 'support/init/init-script.php';
$err = id(new PhutilExecPassthru('lsx'))->execute();
var_dump($err);
```

Summary:
Currently there are a number of `--config extensions.blah=` sprinkled throughout the Mercurial APIs which aren't pleasant to look at. Additionally it turns out the `rebase` command requires the `rebase` extension which is not turned on by default. Uses of `rebase` should also be including this flag to enable the extension when it's in use.
This adds `ArcanistMercurialAPI::buildMercurialExtensionCommand()` which allows running a Mercurial command that requires an extension just by naming the extension instead of providing the full `--config..` argument.
It can be used e.g.
```lang=php
$api->execxLocalWithExtension(
'strip',
'strip --rev %s --',
$rev);
$api->execxLocalWithExtension(
'arc-hg',
'arc-amend --logfile %s',
$tmp_file);
```
Which produces
```lang=console
$ hg --encoding utf-8 --config 'extensions.strip=' strip --rev 82567759e2d703e1e0497f5f41363de3a1500188 --
$ hg --encoding utf-8 --config 'extensions.arg-hg=/Users/cspeckrun/Source/phacility/arcanist/support/hg/arc-hg.py' arc-amend --logfile /private/var/folders/cg/364w44254v5767ydf_x1tg_80000gn/T/6bwck66ccx0kwskw/89989-5F8JaL
```

Test Plan: I ran through several scenarios of running `arc diff` and `arc land` with uncommitted changes on non-head commits, while not having the `evolve` extension enabled. Using the `--trace` argument I verified that `rebase`, `strip`, `arc-amend`, and `arc-ls-markers` were all invoked and the corresponding `arc diff` and `arc land` commands succeeded. I also ran `arc land --onto-remote default` while `arc-hg.py` raised an exception for the "remote" case and verified that the error was caught by Arcanist and displayed the error and prevented further execution. I removed the error from `arc-hg.py` and re-ran the command and verified it succeeded.
