b088331ec0 Simplify handshake hash handling.
Rather than support arbitrarily many handshake hashes in the general
case (which the PRF logic assumes is capped at two), special-case the
MD5/SHA1 two-hash combination and otherwise maintain a single rolling
hash.

5375fd594b Switch the handshake buffer from memory BIO to BUF_MEM.
A memory BIO is internally a BUF_MEM anyway. There's no need to bring
BIO_write into the mix. BUF_MEM is size_t clean.

9550c3ac8b Decouple the handshake buffer and digest.
The handshake hash is initialized from the buffer as soon as the cipher
is known. When adding a message to the transcript, independently update
the buffer and rolling hash, whichever is active. This avoids the
complications around dont_free_handshake_buffer and EMS.

4841ce49a0 Fix EVP_Cipher error-handling.
Turns out the EVP_CIPH_FLAG_CUSTOM_CIPHER ciphers (i.e. legacy EVP_CIPHER
AES-GCM) have a completely different return value setup than the normal ones
which are the standard one/zero. (Except that they never return zero; see
TODO.)

Fix checks in ssl/ and remove remnants of EVP_CIPH_FLAG_CUSTOM_CIPHER in ssl/
as we're using EVP_AEAD now.

better be tidy. Note this is slightly different from upstream's: EVP_Cipher is
documented to return -1 on failure, not 0.

69a01608f3 Add malloc failure tests.
This commit fixes a number of crashes caused by malloc failures. They
were found using the -malloc-test=0 option to runner.go which runs tests
many times, causing a different allocation call to fail in each case.

(This test only works on Linux and only looks for crashes caused by
allocation failures, not memory leaks or other errors.)

This is not the complete set of crashes! More can be found by collecting
core dumps from running with -malloc-test=0.

854dd654d1 Refactor server-side CertificateVerify handling.
This moves CertificateVerify digest processing to the new
SSL_GET_MESSAGE_DONT_HASH_MESSAGE flag. It also refactors it similarly to
ssl3_send_cert_verify and moves that logic to a common ssl3_cert_verify_hash
function to compute the handshake hash.

This removes a large chunk of duplicate (and divergent!) logic between TLS and
DTLS. It also removes TLS1_FLAGS_KEEP_HANDSHAKE.
