Also switch to uint64_t as that's used on master and makes the code
simpler to fix.
Closes GH-20807.

Mirror the mdata_used protection pattern from php_pcre_replace_func_impl
in php_pcre_match_impl, php_pcre_replace_impl, php_pcre_split_impl,
and php_pcre_grep_impl.

Newer PCRE2 rejects \K in lookarounds at compile time, so the
negative-length match code path can no longer be triggered from
userland PHP. The PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK flag that would
re-enable it is only settable via the C compile context API.
Disable resource-heavy tests by default (>1GB of memory usage), unless the
RUN_RESOURCE_HEAVY_TESTS env variable is set.

Add support for new functions present in recent libsodium versions:
- Functions for IP address encryption:
- sodium_crypto_ipcrypt_*
- sodium_bin2ip/sodium_ip2bin helpers
- Extendable output functions:
- SHAKE128/SHAKE256
- TurboSHAKE128/TurboSHAKE256
Fix pcre2_code leak when pcre2_pattern_info() fails after a successful
pcre2_compile(), and fix match_sets/match_data/marks leak when
offsets[1] < offsets[0] in php_pcre_match_impl().

internal refactorings:
- pcntl_signal_get_handler() max signals handling simplification,
reusing the num_signals global.
- pcntl_alarm() accepts a zend_long (signed) but passes it to alarm(),
which takes an unsigned int. Negative values silently wrap to large
unsigned values, scheduling an alarm far in the future instead of
raising an error. Also reject large values above unsigned long
max value.

When a PCRE execution error occurs (e.g. malformed UTF-8 with /u
modifier), preg_grep() was returning a partial result array containing
only the entries processed before the error. All other preg_* functions
return false on execution errors.
After the match loop, check PCRE_G(error_code) and if an error
occurred, destroy the partial array and return false instead.
Fixes GH-11936
Since GH-15021 preloaded constants are propagated to compiled scripts. This is
problematic for file cache, which assumes all referenced zvals are either
persistently allocated or local to the current script. However, preloaded
constants live in shm as immutable, but not persistent.
To solve this, we'd need to duplicate propagated constants in the optimizer when
file cache is used. This is error prone given it needs to happen in many places.
It's debatable whether constant propagation is even correct in this case, as
running the preloaded script on a restart isn't guaranteed to produce the same
result.
Hence, avoid the issue for now by just not relying on preloaded symbols when
file cache is used.
