Tidy up keyblock and CCS logic slightly.
Move the actual SSL_AEAD_CTX swap into the record layer. Also revise the
intermediate state we store between setup_key_block and
change_cipher_state. With SSL_AEAD_CTX_new abstracted out, keeping the
EVP_AEAD around doesn't make much sense. Just store enough to partition
the key block.
