Check for shm_open() in libroot to support Haiku

Resides on libroot (system runtime) on this platform.

Fail in `./configure` when no opcache shm backends exist

This can be seen when the `./configure` step fails to detect `HAVE_SHM_*`,
e.g. due to missing a necessary dependency to compile the test scripts.
(Run `./configure`, run `yum install libtool-ltdl-devel` for missing dependencies,
then run `make`, and php can end up built with 0 shared memory opcache caches)

Give a clearer error message than `unknown`
Searching for `opcache "Fatal Error Unable to allocate shared memory segment of"
"unknown: No such file or directory"` reveals issues such as

Remove unused HAVE_SHM_MMAP_ZERO and HAVE_SHM_MMAP_FILE

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
560ed89bfbb56526251e9bd2fbcb27e5932641d8 which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6911c785f698d724b2ff61e7aebb737 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

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

Little detection change proposal.

As pointed out, the further path is called by open rather than shm_open.

Don't build JIT if the host architecture doesn't support it

Also display in phpinfo() whether JIT is unavailable/disabled/enabled.

Avoid dependency on "struct flock" fields order.

Remove --disable-opcache-filecache option

This is no longer an experimental feature, and we have the ability

Fix bug #77361 (configure fails on 64-bit AIX when opcache enabled)

In f9048300123, 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.
