This changes make FPM always decode SCRIPT_FILENAME when Apache
ProxyPass or ProxyPassMatch is used. It also introduces a new INI
option fastcgi.script_path_encoded that allows using the previous
behavior of not decoding the path. The INI is introduced because
there is a chance that some users could use encoded file paths in
their file system as a workaround for the previous behavior.

This fixes a ZEND_RC_MOD_CHECK() assertion failure when building with
"-DZEND_RC_DEBUG=1 --enable-debug --enable-zts". php_dl() is called after
startup, and manipulates the refcount of persistent strings, which is not
allowed at this point of the lifecycle.
The dl() function disables the ZEND_RC_MOD_CHECK() assertion before calling
php_dl(). This change applies the same workaround in FPM.

This functionality didn't actually work.
This was discussed on the mailing list [1] and no one objected.

On Windows, the cli and phpdbg SAPIs have variants (cli-win32 and
phpdbgs, respectively) which are build by default. However, the
variants share some files, what leads to duplicate build rules in the
generated Makefile. NMake throws warning U4004[1], but proceeds
happily, ignoring the second build rule. That means that different
flags for duplicate rules are ignored, hinting at a potential problem.
We solve this by introducing an additional (optional) argument to
`SAPI()` and `ADD_SOURCES()` which can be used to avoid such duplicate
build rules. It's left to the SAPI maintainers to make sure that
appropriate rules are created. We fix this for phpdbgs right away,
which currently couldn't be build without phpdbg due to the missing
define; we remove the unused `PHP_PHPDBG_EXPORTS` flag altogether.

The phpdbg issue is a real issue, although it's unlikely that harm can
be done due to stack alignment and little-endianess. The others seem
to be more cosmetic.
Internal function won't need their refcount increased as they outlive
the debugger session, and userland functions won't be unloaded either.
So no refcount management is necessary for registered functions.

The reason this breaks is because of a type mismatch.
The following line uses fields of the timeval struct which are both 8 bytes on
Alpine 32-bit, which results in a computed value of also 8 bytes:
https://github.com/php/php-src/blob/b09ed9a0f25cda8c9eea9d140c01587cd50b4aa8/sapi/fpm/fpm/fpm_status.c#L611
However, it is passed to a format string which expects 4 bytes
(`unsigned long` and thus the `%lu` format specifier is 4 bytes on Alpine 32-bit),
resulting in argument corruption.
Since the value is generally small, truncating to 4 bytes is sufficient to fix this.
Closes GH-17286.
For some reason, terminating the child process by sending CTRL+C won't
work under ASan instrumentation. Since termination via CTRL+BREAK
works, there is apparently nothing fundamentally wrong, so we just
skip the test.
Closes GH-17086.
