* random.c (random_s_bytes): new method Random.bytes, which is
equivalent to Random::DEFAULT.bytes. [Feature #4938]

FrozenError will be used instead of RuntimeError for exceptions
raised when there is an attempt to modify a frozen object. The
reason for this change is to differentiate exceptions related
to frozen objects from generic exceptions such as those generated
by Kernel#raise without an exception class.

* random.c (get_rnd, try_get_rnd): ensure initialized to get rid
of crash in forked processes. [ruby-core:82100] [Bug #13753]

* 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.

rand method, not to call toplevel rand method.

When you change this to true, you may need to add more tests.

construction bits to Init_RandomSeed2. Random::DEFAULT
and Ruby internal hashes are no longer shared their seed.
* random.c (Init_RandomSeed2): ditto. And, kill evil
rb_obj_reveal() stuff.
* random.c (init_hashseed): add MT argument.
* random.c: (init_siphash): ditto.
* test/ruby/test_rand.rb (TestRand#test_default_seed): new
test for Random::DEFAULT::seed.

precision of long may be larger than double.
