readdir_r() is deprecated in modern glibc versions. readdir() is
thread safe in practice, as long as there are no concurrent accesses
on the *same* directory stream.
This is only relevant for the gcrypt backend, which is no longer in
use. I couldn't find any hard info on when exactly gcrypt support was
dropped, but nette is the default since 2.11.1. Most code that still
has the gcrypt handling is checking against < 2.12. In either case,
those versions were released in 2010/2011.
We're not using this anywhere, and it causes warnings, so I'm
dropping it. If we do end up needing this, it should be reintroduced
with a ZEND_ prefix.
We're not checking the return value and the NTS version of this
generates warnings. If we want to handle lock failures, we should
do a hard abort inside tsrm_env_lock() itself.
Fix pgsql use after free trying to reuse closed connection
When a connection is closed, we also need to remove the hash entry
from the regular_list, as it now points to freed memory. To do this
store a reverse mapping from the connection to the hash string.
It would be nicer to introduce a wrapping structure for the pgsql
link resource that could store the hash (and notices), but that would
require large changes to the extension, so I'm going for a more
minimal fix here.

Remove duplicated substitude for Makefile
The substitution is already done in the CLI's config.m4 file. Current
SAPIs only provide one PHP_EXECUTABLE variable, i.e. PHP CLI so the one
in the configure.ac can be removed.

Remove HAVE_STRERROR
Checking for the strerror function presence is no longer needed since it
is part of the C89 standard [1] and can be safely assumed that all
current systems have it.
Check in the configure.ac and Windows defined symbol are still left
until the file library (libmagic) will be updated.
Added range options to the float validation filter
php_filter_int (called via the constant FILTER_VALIDATE_INT) has the options min_range
and max_range. they allow the user to not only test if a value is a double but also if
the value is inside a specific range. php_filter_float (called via the constant
FILTER_VALIDATE_FLOAT) didn't provide this yet, making validation of numeric but
not-only-int values more complicated for the user.
this commits implements the options min_range and max_range for the function
php_filter_float to fix this inconsistency.

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.

Remove HAVE_SIGNAL_H
The `<signal.h>` header file is part of the standard C89 headers [1] and
on current systems can be included unconditionally.
Since file requires at least C89 or greater, the `HAVE_SIGNAL_H` symbol
defined by Autoconf in Zend.m4 [2] can be ommitted and simplifed.
The bundled libmagic (file) also ommits the usage of HAVE_SIGNAL_H since
5.35 however current version in PHP is very modified 5.34 version and
will be refactored separately. Check for HAVE_SIGNAL_H is therefore
still done in the configure.ac.

Remove HAVE_LIMITS_H
The `<limits.h>` header file is part of the standard C89 headers [1]
and on current systems can be included unconditionally.
Since PHP requires at least C89 or greater, the `HAVE_LIMITS_H` symbol
defined by Autoconf in configure.ac [2] can be ommitted and simplifed
however due to bundled file library (libmagic) and timelib still using
it, the removal there was omitted and done only in Zend.m4 file.
Current bundled libraries libtime, oniguruma, and libmagic still include
partial `HAVE_LIMITS_H` usage and will be more refactored when this is
possible.

Refactor AC_INIT in configure.ac and PHP versions
Since Autoconf 2.53 the AC_INIT call with only a single argument has
been made obsolete and now includes several other optional arguments to
make installation experience a bit better by providing program version
and links to the project in the `./configure -h` output. This patch also
updates win build version. The phpize.m4 AC_INIT has been updated with
the call without arguments.
Always use ZEND_SECURE_ZERO() when cleaning up data
Optimizing compilers have an annoying tendency to throw out
memsets over data that they think aren't used anymore. Apply secure
zero-out in cases where this has potential to happen.
Commit 6a624c1[1] mostly replaced `COMPILER_NAME` with
`COMPILER_NAME_LONG` and `COMPILER_NAME_SHORT`, but not all
occurrences, what broke the Clang ASAN configuration. We fix this by
getting rid of `COMPILER_NAME` altogether.
