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.

random: Move the CSPRNG implementation into a separate C file (#10668)

The CSPRNG is a delicate and security relevant piece of code and having it in
the giant random.c makes it much hard

random: Move the CSPRNG implementation into a separate C file (#10668)

The CSPRNG is a delicate and security relevant piece of code and having it in
the giant random.c makes it much harder to verify changes to it. Split it into
