Fix DTLS_ANY_VERSION and add tests.
This fixes bugs that kept the tests from working:
- Resolve DTLS version and cookie before the session.
- In DTLS_ANY_VERSION, ServerHello should be read with first_packet = 1. This
is a regression from f2fedefdcaf62f10b566f55858c25f35112072ea. We'll want to
do the same for TLS, but first let's change this to a boolean has_version in a
follow-up.
Things not yet fixed:
- DTLS code is not EVP_AEAD-aware. Those ciphers are disabled for now.
- On the client, DTLS_ANY_VERSION creates SSL_SESSIONs with the wrong
ssl_version. The tests pass because we no longer enforce the match as of
e37216f56009fbf48c3a1e733b7a546ca6dfc2af. (In fact, we've gone from the server
ignoring ssl_version and client enforcing to the client mostly ignoring
ssl_version and the server enforcing.)
- ssl3_send_client_hello's ssl_version check checks for equality against
s->version rather than >.
