Don't pollute the embedder's namespace with a session_ctx macro. It looks like
the difference was that, without TLS extensions, session_ctx was ctx rather
than initial_ctx. Now it's always initial_ctx. Retain the semantics of
switching SSL_CTX's out after the fact, until/unless we decide to replace that
with something less scary-sounding.

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.

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.

09bd58d1f1 flipped a condition. Doing that
memset in the DTLS case breaks retransmits across a CCS and fails to memset in
the TLS case.
Strangely, it didn't break any tests, but I think that's a function of us
lacking renego tests. The sequence number doesn't seem to be used in the
initial handshake for TLS, so it stayed at zero. After a renego, that codepath
is relevant.

beautiful due to the "standard" that it's trying to implement. (See

The references from the PKCS#8 code to various ciphers have digests have
been made into function pointer references rather than NIDs so that the

A bug that crashed OpenSSL/BoringSSL when parsing a malformed PKCS#8

the BER support is removed from them and moved to a separate function

To align with what Chrome sends on NSS, remove all 3DES cipher suites except
RSA_WITH_3DES_EDE_CBC_SHA. This avoids having to order a PFS 3DES cipher
against a non-PFS 3DES cipher.
Remove the strength sort which wanted place AES_256_CBC ahead of AES_128_GCM
and is not especially useful (everything under 128 is either 3DES or DES).
Instead, explicitly order all the bulk ciphers. Continue to prefer PFS over
non-PFS and ECDHE over DHE.
This gives the following order in Chromium. We can probably prune it a bit
(DHE_DSS, DH_*) in a follow-up.
