getrandom(2) and read(2) (from /dev/urandom) may return a random buffer
whose length is shorter than required. This change makes sure that they
get enough buffer by using a loop.

* random.c (InitVM_Random): rename Random.raw_seed to
Random.urandom. A quick search seems there are no practical use
of this method than securerandom.rb so I think it's OK to rename
but if there are users of it, this hunk is subject to revert.
* test/ruby/test_rand.rb (TestRand#test_urandom): test for it.
* lib/securerandom.rb (SecureRandom.gen_random): Prefer OS-
provided CSPRNG if available. Otherwise falls back to OpenSSL.
Current preference is:
1. CSPRNG routine that the OS has; one of
- getrandom(2),
- arc4random(3), or
- CryptGenRandom()
2. /dev/urandom device
3. OpenSSL's RAND_bytes(3)
If none of above random number generators are available, you
cannot use this module. An exception is raised that case.

glibc still does not define the SYS_getrandom alias for
__NR_getrandom in the Linux kernel. However, installing
up-to-date Linux kernel headers (linux-libc-dev >= 3.17 package
on Debian) will get the __NR_getrandom syscall number defined
properly without relying on glibc.
This allows users with a modern kernel+headers to use the getrandom
syscall without waiting on glibc support.

It is meaningless. If SYS_getrandom(GRND_NONBLOCK) return
EAGAIN, we eventually call fill_random_bytes_urandom() and
it block such as SYS_getrandom() without GRND_NONBLOCK.
