This is a bit of cleanup that probably should have been done at the same time
as 30ddb434bf.
For now, version negotiation is implemented with a method swap. It also
performs this swap on SSL_set_session, but this was neutered in
30ddb434bf. Rather than hackishly neuter it,
remove it outright. In addition, remove SSL_set_ssl_method. Now all method
swaps are internal: SSLv23_method switch to a version-specific method and
SSL_clear undoing it.
Note that this does change behavior: if an SSL* is created with one
version-specific method and we SSL_set_session to a session from a /different/
version, we would switch to the /other/ version-specific method. This is
extremely confusing, so it's unlikely anyone was actually expecting it.
Version-specific methods in general don't work well.

This is only used for EAP-FAST which we apparently don't need to support.
Remove it outright. We broke it in 9eaeef81fa by
failing to account for session misses.
If this changes and we need it later, we can resurrect it. Preferably
implemented differently: the current implementation is bolted badly onto the
handshake. Ideally use the supplied callbacks to fabricate an appropriate
SSL_SESSION and resume that with as much of the normal session ticket flow as
possible.
The one difference is that EAP-FAST seems to require the probing mechanism for
session tickets rather than the sane session ID echoing version. We can
reimplement that by asking the record layer to probe ahead for one byte.

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 fixes version mismatches on resumption without rewriting the entirety of
OpenSSL's version negotiation logic. (Which still badly needs to happen.)

It was added in OpenSSL 1.0.2, so nothing can be depending on it yet. If we
really want a Suite B profile, it seems better to generate a configuration for
the rest of the system rather than pepper the codebase with checks.

Without SSLv2, all cipher suite values are 2 bytes. Represent them as a
uint16_t and make all functions pass those around rather than pointers.
This removes SSL_CIPHER_find as it's unused.

Accepting them as a server is still necessary, but this code is unreachable.
Without SSLv2 support, none of the cipher suites are SSLv2, so
ssl23_no_ssl2_ciphers always returns true and we send a V3ClientHello.

Some of the limit checks reference p rather than ret. p is the original
buffer position, not the current one. Fix those and rename p to orig so
it's clearer.
