Beyond generally eliminating unnecessary includes, eliminate as many
includes of headers that declare/define particularly error-prone
functionality like strlen, malloc, and free. crypto/err/internal.h was
added to remove the dependency on openssl/thread.h from the public
openssl/err.h header. The include of <stdlib.h> in openssl/mem.h was
retained since it defines OPENSSL_malloc and friends as macros around
the stdlib.h functions. The public x509.h, x509v3.h, and ssl.h headers
were not changed in order to minimize breakage of source compatibility
with external code.

As of our 82b7da271ff13a2878e921f0d262812d111a7b84, an SSL_SESSION created
externally always has a cipher set. Unknown ciphers are rejected early. Prior
to that, an SSL_SESSION would only have a valid cipher or valid cipher_id
depending on whether it came from an internal or external session cache.
See upstream's 6a8afe2201 and
c566205319 for more context.
Since we don't get ourselves into this strange situation and s->cipher is now
always valid for established SSL_SESSION objects (the existence of
unestablished SSL_SESSION objects during a handshake is awkward, but something
to deal with later), do away with s->cipher_id altogether. An application
should be able to handle failing to parse an SSL_SESSION instead of parsing it
successfuly but rejecting all resumptions.

There's not much point in retaining the identity hint in the SSL_SESSION. This
avoids the complexity around setting psk_identity hint on either the SSL or the
SSL_SESSION. Introduce a peer_psk_identity_hint for the client to store the one
received from the server.
This changes the semantics of SSL_get_psk_identity_hint; it now only returns
the value configured for the server. The client learns the hint through the
callback. This is compatible with the one use of this API in conscrypt (it
pulls the hint back out to pass to a callback).

Deprecate the old two-pass version of the function. If the ticket is too long,
replace it with a placeholder value but keep the connection working.

Doing some archeaology, since the initial OpenSSL commit, key_arg has been
omitted from the serialization if key_arg_length was 0. Since this is an
SSLv2-only field and resuming an SSLv2 session with SSLv3+ is not possible,
there is no need to support parsing those sessions.
Interestingly, it is actually not the case that key_arg_length was only ever
set in SSLv2, historically. In the initial commit of OpenSSL, SSLeay 0.8.1b,
key_arg was used to store what appears to be the IV. That was then removed in
the next commit, an import of SSLeay 0.9.0b, at which point key_arg was only
ever set in SSLv3. That is old enough that there is certainly no need to
parse pre-SSLeay-0.9.0b sessions...

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.

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.

This was done for the server when parsing a session ticket, but it
wasn't done in the parsing function itself. That caused problems when
high level code used the parsing function directly to set a session for
the client code.
