Fix the aligned variable attribute check (#14211)

By default compilers may not treat attribute warnings as errors when
encountering an unknown __attribute__, unless some error option is
provided (-Werror=attributes, -Werror=unknown-attributes, -Werror...).
This fixes the check and wraps it into a separate M4 macro to be
extendable in the future if needed. It checks if conftest.err file was
generated by the compilation check when warnings appear. Also, PHP check
is a bit customized by using __alignof__ keyword, so it is left in there
for now to not break existing checks.

Use AC_SEARCH_LIBS for socketpair, gethostname and gethostbyaddr (#14116)

Use AC_SEARCH_LIBS for socketpair, gethostname and gethostbyaddr (#14116)

The socketpair():
* C library: Solaris 11.4 and most other systems
* libsocket: Solaris <= 11.3 and illumos
* libnetwork: Haiku

The gethostname() check is moved to AC_CHECK_FUNCS:
* C library: most systems
* libnsl: none
* libnetwork: Haiku (which is already checked in the libraries section)

The gethostbyaddr():
* C library: most systems, Solaris 11.4
* libnsl: Solaris 11.3, illumos
* libnetwork: Haiku

This also removes redundant unused symbols:
- HAVE_GETHOSTBYADDR
- HAVE_LIBNETWORK
- HAVE_LIBNSL

The outdated comment about -lnsl and -lsocket linking has been removed
because these systems are long not supported anymore and this issue is
not relevant anymore like mentioned. The initial solution was different
than the one with the PHP_CHECK_FUNC macros at the current versions.
See commit a188fac946a65f4dcc2c6a0f37b0799d74500741 where the
gethostbyaddr() was checked conditionally based on the gethostname()
availability in libc. Main issue was mostly related to the redundant nsl
library being always linked because of the AC_CHECK_LIB.

Refactor root build directories (#13785)

This adds all root build directories in one call. PEAR directory is
created only when enabled and duplicated Zend directory creation is
removed, because it was intended for the zend_config.h when building
out-of-source or using the config.status manually before the
PHP_ADD_BUILD_DIR was introduced in the build system.

Make `--enable-embed` libs respect `--libdir`

And make locatable by via `php-config`. Prior to this, `libphp.*`
would always install to `$prefix/lib`. After this, they will install
to `$libdir`.

In practice, this will make it so that programs embedding libphp can
use `php-config` to determine appropriate compile flags without
guessing.

In `configure.ac`, it seems `$libdir` is mutated in some instances.
Ideally the mutated version would be stored in `$phplibdir` or
something. Instead of tracking down all uses of that variable, I
introduced another variable `$orig_libdir` that holds the original
value passed to the configure script.

This is a no-op for users unless they are compiling with `--libdir`
set to something other than `$prefix/lib`, the default.

Create modules directory in a centralized location (#13411)

Shared objects of extensions during the *nix build are copied to the
`modules` directory. It is a practice established since the early days
of the PHP build system. Other build systems may have similar concept of
"library destination directory". On Windows, they are put into the root
build directory. Such directory simplifies collection of the shared
extensions during testing, or when running the cli executable at the end
of the build process.

This change ensures that the directory is consistently created in a
single location, for both the primary PHP build process and when
utilizing `phpize` within community extensions.

The AC_CONFIG_COMMANDS_PRE is executed at the end of the configuration
phase, before creating the config.status script, where also build
directories and global Makefile are created.

The pwd is executed using the recommended $(...) instead of the obsolete
backticks. Autoconf automatically locates the proper shell and
re-executes the configure script if such case is found that $(...) is
not supported (the initial /bin/sh on Solaris 10, for example).

Check major, minor and makedev with Autoconf's AC_HEADER_MAJOR (#13706)

The non-standard major(), minor(), and makedev() can be defined as
macros. These are usually used together with the Autoconf macro
AC_HEADER_MAJOR, which defines the MAJOR_IN_MKDEV if sys/mkdev.h is
available, or MAJOR_IN_SYSMACROS if sys/sysmacros.h is available.

On Solaris/illumos they are in the sys/mkdev.h header (macro defined to
libc implementation) and in sys/sysmacros.h (macro defined with binary
operators and bits shifting). On systems with musl and glibc 2.28 or
later they are defined in sys/sysmacros.h, in glibc 2.27 and earlier
they were in sys/types.h. On BSD-based systems and macOS they are in the
sys/types.h.

Autoconf 2.70 has fixed the AC_HEADER_MAJOR macro, so it detects the
headers properly due to glibc 2.25 throwing deprecation warnings when
using the macros from sys/types.h. With Autoconf 2.69 and earlier the
ac_cv_header_sys_types_h_makedev cache variable can skip the
improper sys/types.h check in the macro.

This change syncs the usage within the ext/fileinfo/libmagic bundled
library and ext/posix.

When sys/mkdev.h header is available, code includes that, otherwise
it conditionally includes the sys/sysmacros.h. The ext/posix has
additional check whether linker sees the makedev, otherwise it checks
if makedev is declared within the given set of headers accoring to the
AC_HEADER_MAJOR logic. Previously the AC_CHECK_FUNCS didn't detect it.

Implement fcontext handling for sparc64_sysv_elf.

This was tested on OpenBSD sparc64 and all fiber related tests pass.
On OpenBSD stackghost prevents the modification of the return address
and therefor an extra trampoline is needed in make_fcontext(). This
should not matter on other OS implementing sysv ABI and the trampoline
should work there as well.
