Checks getrandom availability on solaris.

To fix part of GH-15381.
gcc nor clang provides a constant to distinguish illumos and solaris
not the system provides a kernel version stamp like the BSD.
thus, we simply check the symbol and remaing purposely conservative in
the existing logic, using it only for solaris to avoid unexpected
breakages for other systems. would need a different fix for higher
branches.

Normalize AC_CHECK_HEADER* arguments (#14723)

The m4_normalize is for Autoconf < 2.70 (on 2.70 and later versions a
blank-or-newline separated items can be expanded without using
backslash-newline). The order of headers in configure.ac is left as is
because the first few headers depend on checking other headers (for
those includes the 4th argument).

Rename HAVE_DECL_ARC4RANDOM_BUF to HAVE_ARC4RANDOM_BUF (#14565)

Rename HAVE_DECL_ARC4RANDOM_BUF to HAVE_ARC4RANDOM_BUF (#14565)

AC_CHECK_DECLS defines HAVE_DECL_ARC4RANDOM_BUF to 0 or 1. On Windows
this isn't defined to 0. To avoid the undefined state, the AC_CHECK_DECL
is used to manually define the HAVE_ARC4RANDOM_BUF to 1 if declaration
is found, otherwise undefined.

In the future on current platforms, also AC_CHECK_FUNCS can be used
instead since the arc4random_buf is located in default libraries (C)
with declaration available in headers.

random: Move CSPRNG API into php_random_csprng.h (#13290)

This allows consumers of just the CSPRNG to include a much smaller header. It
also allows to verify at a glance whether a source file might use non-secure
randomness.

This commit includes the new header wherever the CSPRNG is used, possibly
replacing the inclusion of php_random.h if nothing else is used, but also
includes it in the main php_random.h header for compatibility.

Somewhat related to 45f8cfaf104f504340b0073b9736bb50a88d70a1,
2b30f18708b4f73d2c1d29d3a92a606ebdc5ac4c, and

random: Split the uint128 implementation into its own header (#13132)

The implementation of `php_random_uint128_*` exists specifically for
pcgoneseq128xslrr66 and takes up a third of php_random.h. Split it into its own
header to keep php_random.h focused on the functionality directly related to
randomness.
