8750fe58f4 base64: fix underflow in EVP_EncodeBlock.
When I switched the base64 code to use size_t, I missed that one of the
loops was counting down, not up, and depended on the loop variable going
negative.

Additionally this change fixes a bug in NETSCAPE_SPKI_b64_encode where
the size of the result buffer was incorrectly calculated and a possible
memory leak.

449f16b947 Change ECDSA_METHOD's size() to group_order_size()
The |size| method was documented to return the same as |ECDSA_size| -
the max size of an ECDSA signature. However, this involves some ASN.1
calculations which is best done once. What custom implementations want
to give is the size of the group order on which the ASN.1 computations
are based.

This change switches the |size| method to allow that.

Also fix some DTLS cookie bugs. rcvd_cookie is never referenced after being
saved (and the length isn't saved, so it couldn't be used anyway), and the
cookie verification failed to check the length.

For convenience, add a CBS_mem_equal helper function. Saves a bit of

14c83e7d00 Refactor PSK logic in ssl3_get_client_key_exchange.
This avoids duplicating the code to build the final premaster in PSK and
ECDHE_PSK. It also ports it to CBB for an initial trial of the API. Computing
the premaster secret now proceeds in four steps:

1. If a PSK key exchange (alg_a), look up the pre-shared key.
2. Compute the premaster secret based on alg_k. If PSK, it's all zeros.
3. If a PSK key exchange (alg_a), wrap the premaster in a struct with the
   pre-shared key.
4. Use the possibly modified premaster to compute the master secret.

e8f3d666cc Be strict about expecting a server Certificate message.
Introduce a ssl_cipher_has_server_public_key to save the repeated
NULL/PSK/RSA_PSK[*] check. Don't allow skipping to ServerKeyExchange when
expecting Certificate; the messages expected are determined by the cipher
suite. The ssl3_get_server_public_key call is already guarded.

As the previous test demonstrates, this is safe because of the
ssl3_check_cert_and_algorithm call, but avoid the looseness in the parsing
there.

[*] NB: we don't implement RSA_PSK, and OpenSSL has never implemented it.

676d1e780e Separate client and server certificate_types.
This is the first of reorganizing state between connection state and handshake
state. The existing set are retained in cert_st for the server; they are server
configuration. The client gets a copy in s->s3->tmp alongside other handshake
state.

With other handshake state moved there, hopefully we can reset that state in
one go and possibly not even maintain it when there is no handshake in
progress.  Rather than currently where we sometimes confused connection state
and handshake state and have to reset as appropriate on renegotiate.

While I'm here, document the fields and name them something more useful than
'ctypes'.
