Refactor Zend/acinclude.m4 local macro

There is now only a single M4 macro in the legacy acinclude.m4 file. A
separate acinclude file was once used with a standalone Zend engine
building but with current build system this can be simplified a bit.

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.

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 PHP_PROG_BISON and PHP_PROG_RE2C

This patch refactors these macros to also checks for the required given
versions of bison and re2c.

- PHP_PROG_RE2C and PHP_PROG_BISON take optional args - minmimum version
required, and bison also excluded versions.
- Instead of caching values this uses manual checking and messaging
outputs.
- It looks like the minimum version of RE2C 0.13.4 is working ok so far.

The genfiles script improvements:
- Add make override in genfiles
- Move checkings from makedist to genfiles
- Refactored output messages
- Various minor enhancements

Remove legacy AC_CHECK_TYPE calls for uint and ulong

The AC_CHECK_TYPE was refactored in more recent versions of Autoconf
and the call with two arguments is obsolete and not recommended anymore.

This patch also refactors some leftovers of using ulong and uint which
are not standard nor common usages of types in C.

The ulong can be used as zend_ulong and uint usage is actually
`unsigned int`.

The usage of HAVE_ULONG removed since it is not used in current code
base.

Legacy edgecase for some legacy HPUX systems removed:
- sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is
not defined with current build system.

- flags are unsigned int
- max_allowed_packet changed to unsigned int

Remove obsolescent AC_HEADER_STDC and memcpy check

Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems anymore, including the `AC_HEADER_STDC`.

This macro checks if given system has C89 compliant header files such
as `<string.h>`, `<stdlib.h>`, `<stdarg.h>`, `<float.h>`,... and defines
the `STDC_HEADERS` symbol [2]. Case is that current systems should be
well supported with at least C89 standard headers [3].

Given headers are still additionally checked with the `AC_PROG_CC`
macro, yet not needed anyway.

Additionally, the HAVE_MEMCPY check has been removed. The memcpy
function is standardized by C89 and later.

Remove unused PHP_AC_BROKEN_SPRINTF and AC_ZEND_BROKEN_SPRINTF

The sprintf function has been normalized to php_sprintf via

This patch removes the checks to make a custom sprintf function

The ZEND_BROKEN_SPRINTF has been removed and the
hardcoded #define zend_sprintf sprintf is used.

The php_sprintf and zend_sprintf are now symbols to sprintf.

This patch now removes the custom PHP definitions of the php_sprintf and
zend_sprintf functions in favor of the C99 sprintf which is also
standardized in C89 already. Once, on some systems sprintf didn't behave
in same way.

The C89 standard and later defines the `<string.h>` header as part of
the standard headers [1] and on current systems it is always present.

Code included also `<strings.h>` header as an alterinative in some
files. This kind of check was relevant on some older systems where the
`<strings.h>` file included definitions for the C89 compliant
`<string.h>`. Today such alternative check is not required anymore. The
`<strings.h>` file is part of the POSIX definition these days.

Also Autoconf suggests doing this and relying on C89 or above [2] and [3].

This patch also cleans few unused `<strings.h>` inclusions in the libmbfl.
