Summary:
Correct PHPDoc when none of the method calls try to handle a return value.
Add missing fallback `return` statements (which may never be reached if previous condition checks were always true).
This reduces the amount of errors reported by static code analysis tools.
Test Plan: Carefully read the code and check all places in which a function gets called whether a return value is expected.

Summary:
As of February 2024, phurl.io (which is not run by Phorge.it) shows HTTP 503 errors instead of redirecting to the target URIs.
Thus replace any URIs pointing to phurl.io with the corresponding target URIs, based on the mapping listed on https://secure.phabricator.com/phurl/.

Summary: Ref T13588. See D21497. As of PHP 8, the XML entity loader is disabled by default and the `libxml_disable_entity_loader` function is deprecated. Thus suppress the deprecation warning for now; we could skip the function call, but this is safer.
Test Plan:
* Still works with PHP 7.
* No more deprecation message with PHP 8.

Summary:
Ref T13395. "libphutil/" was stripped for parts, but some documentation still references it. This is mostly minor corrections, but:
- Removes "Javelin at Facebook", long obsolete.
- Removes "php FPM warmup", which was always a prototype and is obsoleted by PHP preloading in recent PHP.

Summary:
Ref T13575. Since PHP builtin webserver support was added, the pathway for parsing request parameters became more complex. We now rebuild "$_REQUEST" later, and this rebuild will destroy any mutations made to it here, so the assignment to "__path__" is lost.
Instead of "validating" the request path, make this method "read" the request path and store it explicitly, so it will survive any later request mutations.
Test Plan:
- Submitted any POST form while running Phabricator under the builtin PHP webserver. Old behavior was an error when accessing "__path__"; new behavior is a working application.
- Loaded normal pages, etc.

Summary:
Ref T13507. See that task for discussion. This check appears to be obsolete in all common cases and misfires if the client submits compressed requests.
Since the cases where it could still trigger correctly are extremely rare and should still have plausible behavior, just remove it.

Fixes T13471. Recent versions of PHP raise a warning when this function is called.
We're only calling it so we can instantly fatal if it's enabled, so use "@" to silence the warning.

Summary:
Depends on D20137. Ref T13250. Ref T12101. In versions of PHP beyond 7, various engine errors are gradually changing from internal fatals or internal errors to `Throwables`, a superclass of `Exception`.
This is generally a good change, but code written against PHP 5.x before `Throwable` was introduced may not catch these errors, even when the code is intended to be a top-level exception handler.
(The double-catch pattern here and elsewhere is because `Throwable` does not exist in older PHP, so `catch (Throwable $ex)` catches nothing. The `Exception $ex` clause catches everything in old PHP, the `Throwable $ex` clause catches everything in newer PHP.)
Generalize some `Exception` into `Throwable`.
Test Plan:
- Added a bogus function call to the rendering stack.
- Before change: got a blank page.
- After change: nice exception page.

Summary:
Depends on D18987. See PHI343. Fixes T13060. See also T7339.
When the main process starts up with `LANG=POSIX` (this is the default on Ubuntu) and we later try to run a subprocess with a UTF8 character in the argument list (like `git cat-file blob 🐑.txt`), the argument is not passed to the subprocess correctly.
We already set `LANG=en_US.UTF-8` in the //subprocess// environment, but this only controls behavior for the subprocess itself. It appears that the argument list encoding before the actual subprocess starts depends on the parent process's locale setting, which makes some degree of sense.
Setting `putenv('LANG=en_US.UTF-8')` has no effect on this, but my guess is that the parent process's locale setting is read at startup (rather than read anew from `LANG` every time) and not changed by further modifications of `LANG`.
Using `setlocale(...)` does appear to fix this.
Ideally, installs would probably set some UTF-8-compatible LANG setting as the default. However, this makes setup harder and I couldn't figure out how to do it on our production Ubuntu AMI after spending a reasonable amount of time at it (see T13060).
Since it's very rare that this setting matters, try to just do the right thing. This may fail if "en_US.UTF-8" isn't available, but I think warnings/remedies to this are in the scope of T7339, since we want this locale to exist for other legitimate reasons anyway.
Test Plan:
- Applied this fix in production, processed the failing worker task from PHI343 after kicking Apache hard enough.
- Ran locally with `setlocale(LC_ALL, 'duck.quack')` to make sure a bad/invalid/unavailable setting didn't break anything, didn't hit any issues.

Summary:
Depends on D18702. Ref T13008. This replaces the old hard-coded single rate limit with multiple flexible limits, and defines two types of limits:
- Rate: reject requests if a client has completed too many requests recently.
- Connection: reject requests if a client has too many more connections than disconnections recently.
The connection limit adds +1 to the score for each connection, then adds -1 for each disconnection. So the overall number is how many open connections they have, at least approximately.
Supporting multiple limits will let us do limiting by Hostname and by remote address (e.g., a specific IP can't exceed a low limit, and all requests to a hostname can't exceed a higher limit).
Configuring the new limits looks something like this:
```
PhabricatorStartup::addRateLimit(new PhabricatorClientRateLimit())
->setLimitKey('rate')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(5);
PhabricatorStartup::addRateLimit(new PhabricatorClientConnectionLimit())
->setLimitKey('conn')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(2);
```
Test Plan:
- Configured limits as above.
- Made a lot of requests, got cut off by the rate limit.
- Used `curl --limit-rate -F 'data=@the_letter_m.txt' ...` to upload files really slowly. Got cut off by the connection limit. With `enable_post_data_reading` off, this correctly killed the connections //before// the uploads finished.
- I'll send this stuff to `secure` before production to give it more of a chance.
