SSL test programs: stuff RNG context into a struct

Browse Source 
Group the random generation context (entropy and DRBG) into a struct.
This is in preparation for unifying the common RNG-related code of
ssl_client2 and ssl_server2, then generalizing that code to support
methods other than entropy+CTR_DRBG.
