Allocate temporary PCRE match data using ZMM

Create a separate general context that uses ZMM as allocator and
use it to allocate temporary PCRE match data (there is still one
global match data). There is no requirement that the match data
and the compiled regex / match context use the same general context.

This makes sure that we do not leak persistent memory on bailout
and fixes oss-fuzz #25296, on which half the libfuzzer runs
currently get stuck.

Add pcre_get_compiled_regex_cache_ex() with local_aware flag

A new function `pcre_get_compiled_regex_cache_ex()` is introduced,
which allows to compile regexp pattern using the "C" locale instead
of a current locale.

This will be needed to replace setlocale() usage in fileinfo,
which is not thread-safe.

Remove mention of PHP major version in Copyright headers

Remove checks for locale.h, setlocale, localeconv

Remove checks for locale.h, setlocale, localeconv

The `<loccale.h>` header file, setlocale, and localeconv are part of the
standard C89 [1] and on current systems can be used unconditionally.

Since PHP 7.4 requires at least C89 or greater, the `HAVE_LOCALE_H`,
`HAVE_SETLOCALE`, and `HAVE_LOCALECONV` symbols defined by Autoconf in
configure.ac [2] can be ommitted and simplifed.

The bundled libmagic (file) has also been patched already in version
5.35 and up in upstream location so when it will be patched also in
php-src the check for locale.h header is still left in the configure.ac
and in windows headers definition file.

Don't create a new array for empty/null match every time

If PREG_OFFSET_CAPTURE is used, unmatched subpatterns will be either
[null, -1] or ['', -1] depending on PREG_UNMATCHED_AS_NULL mode.
Instead of creating a new array like this every time, cache it inside
a global (per-request -- could make it immutable though).

Additionally check whether the subpattern is an empty string or
single character string and use an existing interned string in that
case. Empty / single-char subpatterns are common, so let's avoid
allocating strings for them.

Remove unused Git attributes ident

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
