08b65f4e31 Enabling 0-RTT on new Session Tickets.
This adds support for setting 0-RTT mode on tickets minted by
BoringSSL, allowing for testing of the initial handshake knowledge.

6f600d6bae Add experimental TLS 1.3 short record header extension.
This extension will be used to test whether
https://github.com/tlswg/tls13-spec/pull/762 is deployable against
middleboxes. For simplicity, it is mutually exclusive with 0-RTT. If
client and server agree on the extension, TLS 1.3 records will use the
format in the PR rather than what is in draft 18.

eff1e8d9c7 Adding RSA-PSS signature algorithms.
[Rebased and tests added by davidben.]

In doing so, regenerate the test RSA certificate to be 2048-bit RSA.
RSA-PSS with SHA-512 is actually too large for 1024-bit RSA. Also make
the sigalg test loop test versions that do and don't work which subsumes
the ecdsa_sha1 TLS 1.3 test.

For now, RSA-PKCS1 is still allowed because NSS has yet to implement
RSA-PSS and we'd like to avoid complicated interop testing.

13414b3a04 Implement draft-ietf-tls-chacha20-poly1305-04.
Only ECDHE-based ciphers are implemented. To ease the transition, the
pre-standard cipher shares a name with the standard one. The cipher rule parser
is hacked up to match the name to both ciphers. From the perspective of the
cipher suite configuration language, there is only one cipher.

This does mean it is impossible to disable the old variant without a code
change, but this situation will be very short-lived, so this is fine.

Also take this opportunity to make the CK and TXT names align with convention.

standardized as-is, it's not clear we should implement new DHE cipher suites at
this point.)

Chrome UMA, unsurprisingly, shows that it's unused.

e518f65d2c Update references to RFCs.
Some code predated the RFCs themselves, but the RFCs now exist. Also remove
now obsolete comments and some unused #defines.

See upstream's cffeacd91e70712c99c431bf32a655fa1b561482. (Though this predates
it; I just remembered I never uploaded it.)

d1681e614f Remove SSL_set_session_secret_cb (EAP-FAST)
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.

b398d16c1d Remove SSL_check_chain and unexport CERT_PKEY flags.
Both of these are newly-exported in OpenSSL 1.0.2, so they cannot be used by
current consumers.

This was added in upstream's 18d7158809c9722f4c6d2a8af7513577274f9b56 to
support custom selection of certificates. The intent seems to be that you
listen to cert_cb and use SSL_check_chain to lean on OpenSSL to process
signature algorithms list for you.

Unfortunately, the implementation is slightly suspect: it uses the same
function as the codepath which mutates and refers to the CERT_PKEY of the
matching type.  Some access was guarded by check_flags, but this is too
complex. Part of it is also because the matching digest is selected early and
we intend to connect this to EVP_PKEY_supports_digest so it is no longer a
property of just the key type.

Let's remove the hook for now, to unblock removing a lot of complexity. After
cleaning up this area, a function like this could be cleaner to support, but
we already have a version of this: select_certificate_cb and
ssl_early_callback_ctx.
