49ecee098d tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't work 
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;)

This change adds inevitable extension to have different sized hashes and AES key sizes.
In libbb, md5_end() and shaX_end() are extended to return result size instead of void -
this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

target can't, then it needs the memcpy anyways.
