• Implements the above two methods via FFI.
• Adds OpenSSL::OpenSSLError exception class.
• Allows spec/ruby/1.8/library/openssl/random/*_spec.rb to pass.

Note that the behaviour of #pseudo_bytes does not quite match that of ext/openssl as distributed with MRI:

According to man RAND_bytes(3), the return value of RAND_bytes indicates if an error occurred. However, the return value of RAND_pseudo_bytes indicates if the returned bytes are cryptographically secure or not.

ext/openssl appears to treat both cases the same -- raising an OpenSSLError if the return value is 0. For the RAND_pseudo_bytes case, this return value indicates that the returned bytes are not cryptographically secure -- which is reasonable, as the user has specifically requested this!

I think that the behaviour of MRI's ext/openssl is a bug; however, I don't think I have access to a system where RAND_pseudo_bytes returns cryptographically insecure bytes against which to check...

The specs which this patch passes are in the RubySpec repository, but are not yet in the frozen Rubinius specs.
