lib: random utilities
Add a random number(s) generator specific file. The intial functions are based
on what libuuid provide. I did some modifications like avoid WIN32 checks - this
is util-LINUX.
[kzak@redhat.com: - move jrand_seed to lib/randutils.c
- use TLS for jrand_seed (like original code from libuuid)
- use size_t for buffer sizes
- add close() to random_get_bytes]
