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.

Upstream originally sampled the Finished message's hash at ChangeCipherSpec,
but our patches to add messages between the two complicated this. Move DTLS to
this path, but use the new SSL_GET_MESSAGE_DONT_HASH_MESSAGE flag to avoid
special-casing message types in ssl3_get_message.

This replaces the special-case in ssl3_get_message for Channel ID. Also add
ssl3_hash_current_message to hash the current message, taking TLS vs DTLS
handshake header size into account.
One subtlety with this flag is that a message intended to be processed with
SSL_GET_MESSAGE_DONT_HASH_MESSAGE cannot follow an optional message
(reprocessed with reuse_message, etc.). There is an assertion to that effect.
If need be, we can loosen it to requiring that the preceeding optional message
also pass SSL_GET_MESSAGE_DONT_HASH_MESSAGE and then maintain some state to
perform the more accurate assertion, but this is sufficient for now.

The memory freelist maintained by OpenSSL claims to be a performance
optimization for platforms that have a slow malloc/free
implementation. This should not be the case on modern
linux/glibc. Remove the freelist as it poses a potential security
hazard of buffer-reuse that is of "initialized" memory that will not
be caught be tools such as valgrind.

(b) There is no pending handshake data at the point EXPECT_CCS is set.
