It may fail because the BIO_write to the memory BIO can allocate.
Unfortunately, this bubbles up pretty far up now that we've moved the handshake
hash to ssl3_set_handshake_header.

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.

(Imported from upstream's fe78f08d1541211566a5656395186bfbdc61b6f8)
Not sure this is reachable (upstream's PR references custom engines), but
better be tidy. Note this is slightly different from upstream's: EVP_Cipher is
documented to return -1 on failure, not 0.

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.

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.

Based on an original patch by Joel Sing (OpenBSD) who also originally
identified the issue.
(Imported from upstream's 728bd41a159ea16a60111e7c1120ec2a005507b3)
This patch removes support for empty records (which is almost
universally disabled via SSL_OP_ALL) and adds optional support for 1/n-1
record splitting.
The latter is not enabled by default, since it's not typically used on
servers, but it should be enabled in web browsers since there are known
attacks in that case (see BEAST).
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
