Code checking if the needle string `$value` is somewhere in the haystack `"\0"` makes no sense for a single byte (if it did, then `strcmp` instead of `strpos` should have been used) and the created exception output implies that it's supposed to check that a string does not contain NULL bytes.
Thus switch the order of arguments passed to `strpos()` to be correct.

This bug happens at least when Arcanist does not find any related Revision ID.
It seems there is a method that always normalizes the Revision ID, but sometime that is unknown (null).
And so, NULL ends inside a preg_replace(). It's probably OK to have a normalize method that accept wild

When using `proc_open()` with `'bypass_shell' => true` on Windows,
file extensions other than .exe will not be resolved. Various linters
therefore don't work, such as `jshint`, which is actually `jshint.cmd`.
The problem was already observed and fixed in some places (e.g.
ArcanistGitAPI trying to run `git`), but not in ArcanistExternalLinter.
Changes:
* Fix `Filesystem::resolveBinary()` to actually only resolve executable
files on Windows, and not any other files with no extension or with
an extension listed in %PATHEXT%. Those files can be executed by
typing their name in the cmd.exe shell, but not directly by low-level
Windows functions, and we're using `'bypass_shell'` to bypass the
shell.
* Fix `ArcanistExternalLinter::getBinary()` to call
`Filesystem::resolveBinary()` on Windows.
Test Plan:
Run `arc lint` on the Phorge repository while on Windows.

| `new stdclass()` | false |

Note that phutil_nonempty_scalar() was designed just to tell
whenever a scalar is "empty" or not. So it must not explode
when receiving a valid scalar.
So the question is not whenever a boolean is a scalar or not,
but whenever is empty or not. But also this is a clear fact:
| `$v` | `is_scalar($v)` | `!is_empty($v)` | `if(strlen($v))`|
|---------|-----------------|-----------------|-----------------|
| `true` | `true` | `true` | `true` |
| `false` | `true` | `false` | `false` |
In short, now the function does not explode anymore with bool
values. Instead, it says whenever are empty or not.

`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.
Thus make `array_fuse` accept null and return an empty list in such cases.
Closes T15393
Test Plan: Applied this change; afterwards "Method Call Result" page at `/api/project.create` correctly displayed in the web browser.

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.

Test Plan:
I updated my latest mercurial install to 6.4 and verified with `hg --version`.
I created a diff in a mercurial repo and used `arc land` to successfully land
the revision without any exceptions.

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.
Closes T15367
Test Plan:
- run "arc patch <something valid>"
- to you it must continue to work
- (to @ton it starts working right now)

Summary:
After PHP 8.1 the function `rawurlencode()` does not accept anymore the `null` value.
Thus return an empty string when the input parameter is null instead of passing the input parameter to `rawurlencode()`.

Passing `null` to the `$string` parameter of `mb_convert_case()` is deprecated in PHP 8.1.
This is one of the exceptions which block rendering the "Browse Projects" overlay dialog.

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
Test Plan: After adding the additional check, `/differential/diff/create/` showed the expected `Diff Parse Exception` instead.

Summary:
Conduit responds to requests with either `ERR-INVALID-SESSION` or `ERR-INVALID-AUTH` if the request wasn't sufficiently authenticated. Arcanist's `patch` workflow can automatically attempt to recover from situations in which Conduit responds to unauthenticated requests with `ERR-INVALID-SESSION` (by resending an authenticated version of the request), but not `ERR-INVALID-AUTH` - recover from `ERR-INVALID-AUTH` in the same way.
Closes T15333
Test Plan: The company I work for has been running a local clone of Arcanist containing this change in production for over 18 months now with no problems.
