be8a869d96 Fill in alg_bits for CHACHA20_POLY1305 ciphers.
Apparently we left those as zero. Oh well. This only affects
SSL_CIPHER_get_bits, but so long as we have the field, it ought to be correct.

ec4353498c Remove DHE_RSA_WITH_CHACHA20_POLY1305.
This made sense when the cipher might have been standardized as-is, so a
DHE_RSA variant could appease the IETF. Since the standardized variant is going
to have some nonce tweaks anyway, there's no sense in keeping this around. Get
rid of one non-standard cipher suite value early. (Even if they were to be
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.

b088331ec0 Simplify handshake hash handling.
Rather than support arbitrarily many handshake hashes in the general
case (which the PRF logic assumes is capped at two), special-case the
MD5/SHA1 two-hash combination and otherwise maintain a single rolling
hash.

5055c76709 Rename algorithm2 to algorithm_prf.
It's purely the PRF function now, although it's still different from the
rest due to the _DEFAULT field being weird.

b2a985bfb8 Fold away SSL_CIPHER_ALGORITHM2_VARIABLE_NONCE_INCLUDED_IN_RECORD.
It's a property of just algorithm_enc and hopefully AES-GCM will
continue to be the only true AEAD that requires this. Simpler to just
keep it in ssl_aead_ctx.c.

d1d8078025 Fold away certificate slots mechanism.
This allows us to remove the confusing EVP_PKEY argument to the
SSL_PRIVATE_KEY_METHOD wrapper functions. It also simplifies some of the
book-keeping around the CERT structure, as well as the API for
configuring certificates themselves. The current one is a little odd as
some functions automatically route to the slot while others affect the
most recently touched slot. Others still (extra_certs) apply to all
slots, making them not terribly useful.

Consumers with complex needs should use cert_cb or the early callback
(select_certificate_cb) to configure whatever they like based on the
ClientHello.

bb20f52383 Merge the RSA_ENC and RSA_SIGN certificate slots.
The distinction was not well-enforced in the code. In fact, it wasn't
even possible to use the RSA_SIGN slot because ssl_set_pkey and
ssl_set_cert would always use the RSA_ENC slot.

A follow-up will fold away the mechanism altogether, but this is an easy
initial simplfication.

85bc5601ee Add ECDHE-PSK-AES{128,256}-SHA cipher suites.
If we're going to have PSK and use standard cipher suites, this might be
the best that we can do for the moment.

1feb42a2fb Drop ECDHE-PSK-AES-128-GCM.
This is the best PSK cipher suite, but it's non-standard and nobody is
using it. Trivial to bring back in the future if we have need of it.

a1c90a5ce1 Further tidy up cipher logic.
With SSL2 gone, there's no need for this split between the abstract
cipher framework and ciphers. Put the cipher suite table in ssl_cipher.c
and move other SSL_CIPHER logic there. With that gone, prune the
cipher-related hooks in SSL_PROTOCOL_METHOD.
