Summary:
Per https://www.php.net/manual/en/function.mb-convert-encoding.php, as of PHP 8.0.0, a ValueError is thrown if the value of `to_encoding` or `from_encoding` is an invalid encoding but a ValueError is not suppressed by the stfu operator ("@").
Origin of the function:
https://secure.phabricator.com/rPHU72ad8fd0f05b0d84f7d8efd7db62ad0b3ba4431f
Premising that Arcanist elevates warnings to exception, now we just try-catch.
Closes T15423
Test Plan:
On `/diffusion/edit/1/page/encoding/`,
* enter a valid encoding, such as "7bit", successfully changed encoding
* enter a valid encoding with random capitalization, such as "7biT", successfully changed encoding
* enter a valid alias encoding, such as "ISO-10646-UCS-2", successfully changed encoding
* enter a valid alias encoding with random capitalization, such as "isO-10646-uCS-2", successfully changed encoding
* enter an invalid encoding, such as "whatever", get error message "Repository encoding "whatever" is not valid: String conversion from encoding 'UTF-8' to encoding 'whatever' failed: mb_convert_encoding(): Argument #2 ($to_encoding) must be a valid encoding, "whatever" given"
In any case, no exception is shown anymore.

Summary:
Note that booleans are scalars. Full stop.
| is_scalar($v) | Result |
|------------------|--------|
| `"foo"` | true |
| `""` | true |
| `null` | true |
| `0` | true |
| `0.5` | true |
| `true` | true |
| `false` | true |
| `new stdclass()` | false |
| `array()` | false |
Note that phutil_nonempty_scalar() was designed just to tell
whenever a scalar is "empty" or not. So it must not explode
when receiving a valid scalar.
So the question is not whenever a boolean is a scalar or not,
but whenever is empty or not. But also this is a clear fact:
| `$v` | `is_scalar($v)` | `!is_empty($v)` | `if(strlen($v))`|
|---------|-----------------|-----------------|-----------------|
| `true` | `true` | `true` | `true` |
| `false` | `true` | `false` | `false` |
In short, now the function does not explode anymore with bool
values. Instead, it says whenever are empty or not.
In bold the exact changes:
| Value |`phutil_nonempty_scalar($v)`|
|-------------------|----------------------------|
| `"foo"` | true |
| `""` | false |
| `null` | false |
| `0` | true |
| `0.5` | true |
|`obj` with tostring| true |
|`obj` withno tostr.| Exception |
| `array()` | Exception |
| `true` | ~~Exception~~ **true** |
| `false` | ~~Exception~~ **false** |

Summary:
`strlen()` was used in Phabricator to check if a generic value is a non-empty string.
This behavior is deprecated since PHP 8.1. Phorge adopts `phutil_nonempty_stringlike()` as a replacement for string-alike variables.
Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If phutil_nonempty_stringlike() throws an exception in your
instance, report it to Phorge to evaluate and fix that specific corner case.

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
