89abaea141 Reimplement i2d_SSL_SESSION using CBB.
No more need for all the macros. For now, this still follows the two-pass i2d_*
API despite paying a now-unnecessary malloc. The follow-on commit will expose a
more reasonable API and deprecate this one.

180d1eb04c Remove SSL_get_shared_ciphers.
This removes the need to track the client cipher list in the SSL_SESSION. It
also eliminates a field in SSL_SESSION that wasn't serialized by
i2d_SSL_SESSION. It's only used to implement SSL_get_shared_ciphers which is
only used by debug code.

Moreover, it doesn't work anyway. The SSLv2 logic pruned that field to the
common ciphers, but the SSLv3+ logic just stores the client list as-is. I found
no internal callers that were actually compiled (if need be we can stub in
something that always returns the empty string or so).

5b33a5e0dd Merge the get_ssl_method hooks between TLS and SSLv3.
Remove one more difference to worry about switching between TLS and SSLv3
method tables.

Although this does change the get_ssl_method hook for the version-specific
tables (before TLS and SSLv3 would be somewhat partitioned), it does not appear
to do anything. get_ssl_method is only ever called in SSL_set_session for
client session resumption. Either you're using the version-specific method
tables and don't know about other versions anyway or you're using SSLv23 and
don't partition TLS vs SSL3 anyway.

Also remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is to allow for a buggy peer
which pads CBC with N bytes of value N rather than N+1 bytes of value N. This
quirk has been broken since CBC padding checks became constant-time, as
demonstrated by this attempt at a test. (Instead of just decrementing
padding_length, it needs to also keep track of a separate padding_value and not
decrement that one.)

https://boringssl-review.googlesource.com/#/c/1690/

(The quirk would also fall over anyway if the buggy client ever did a session
resumption; then the server speaks first rather than the client, and the quirk
triggered on reading the first encrypted record from the peer.)

No current cipher suites use SHA-224 or SHA-512 MACs. We can restore those
cases if that ever changes, but hopefully any future cipher suites we care

ed8270a55c Fix crash as server when resuming with SNI.
Thanks to Denis Denisov for noting that |host_name| could be used while
uninitialised in the resumption case.

While in the area, this change also renames |servername_done| to
something more reasonable and removes a documented value that was never
used. Additionally, the SNI ack was only sent when not resuming so
calculating whether it should be sent when processing ClientHello
extensions (which is after s->hit has been set) is superfluous.

Lastly, since SNI is only acked by servers, there's no need to worry
about the SNI callback returning NOACK in the client case.

6c7aed048c Client-side OCSP stapling support.
Remove the old implementation which was excessively general. This mirrors the
SCT support and adds a single boolean flag to request an OCSP response with no
responder IDs, extensions, or frills. The response, if received, is stored on
the SSL_SESSION so that it is available for (re)validation on session
resumption; Chromium revalidates the saved auth parameters on resume.

Server support is unimplemented for now. This API will also need to be adjusted
in the future if we implement RFC 6961.
