9a3c8e51e3 Sync functions checks 
Removed unused checks:
- mbsinit check removed, HAVE_MBSINIT removed (not used in php-src)
- mempcpy check removed, HAVE_MEMPCPY removed (not used in php-src anymore since
  560ed89bfb which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6 and
  not used.
- setpgid check removed since HAVE_SETPGID is not used

Moved to a central configure.ac:
- fpclass
- mbrlen moved to configure.ac (since the HAVE_MBRLEN is used accross the php-src)
- sigprocmask
- getcwd
- getwd
- glob
- strfmon
- nice

Duplicated checks removed:
- gethostname
- getlogin
- getpwuid_r
- socketpair

- mprotect check simplified

2079b09854 Clean headers checks 
Some headers were checked multiple times in the main configure.ac file
and in the bundled extensions or SAPIs themselves. Also many of these
checks are then used accross other extensions or SAPIs so a central
configure.ac makes most sense for these checks.

75fb74860d Normalize comments in *nix build system m4 files 
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
  favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now

9df6a1e4dd Add AS_HELP_STRING to *nix build configure options 
The Autoconf's default AS_HELP_STRING macro can properly format help
strings [1] so watching out if columns are aligned manually is not
anymore.

332b58f865 Fix bug #77361 (configure fails on 64-bit AIX when opcache enabled) 
In f904830012, support for GNU Hurd was added to the opcache and
the configure check to ensure the opcache knows the flock struct
layout prior to building was changed check for two cases: BSD layout
and Linux layout. All the existing hard-coded cases in
ZendAccelerator.h follow these two cases, except for 64-bit AIX.
This means that even though building on 64-bit AIX would work,
the configure script refuses to continue.

Add a new configure check for the 64-bit AIX case and a new
compiler definition HAVE_FLOCK_AIX64. Now that all the cases are
covered, simplify the ifdef logic around these three HAVE_FLOCK_*
macros:
- The macOS and the various BSD flavors fall under HAVE_FLOCK_BSD
- Linux, HP-UX, GNU Hurd, 32-bit AIX, and SVR4 environments
  fall under HAVE_FLOCK_LINUX
- 64-bit AIX falls under HAVE_FLOCK_AIX64

The only difference between the existing HAVE_FLOCK_LINUX and
the hard-coded Linux/HP-UX/Hurd case is that the latter
initialized the 5th member to 0, but since the C standard already
says that un-initialized members will be initialized to 0,
it's effectively the same.

4371945b8b Replace obsolete AC_TRY_FOO with AC_FOO_IFELSE 
Autoconf 2.50 released in 2001 made several macros obsolete including
the AC_TRY_RUN, AC_TRY_COMPILE and AC_TRY_LINK:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2

These macros should be replaced with the current AC_FOO_IFELSE instead:
- AC_TRY_RUN with AC_RUN_IFELSE and AC_LANG_SOURCE
- AC_TRY_LINK with AC_LINK_IFELSE and AC_LANG_PROGRAM
- AC_TRY_COMPILE with AC_COMPILE_IFELSE and AC_LANG_PROGRAM

PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version therefore systems
should be well supported by now.

This patch was created with the help of autoupdate script:
autoupdate <file>

8d3f8ca12a 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.

PHP should be configured and built with --enable-huge-code-pages, OS should be configured to provide huge pages.
It's possible to enable/disable this future in php.ini through opcache.enable_huge_code_pages=0/1.
The feature was tested on Linux and provided 2% improvement on real-life apps, because of 2-3 times reduction in number of iTLB misses.
