SecureRandom should try /dev/urandom first [Bug #9569]
* 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.
