This doesn't even change behavior. Unlike local configuration, the peer
can never have multiple certificates anyway. (Even with a renego, the
SESS_CERT is created anew.)
This does lose the implicit certificate type check, but the certificate
type is already checked in ssl3_get_server_certificate and later checked
post-facto in ssl3_check_cert_and_algorithm (except that one seems to
have some bugs like it accepts ECDSA certificates for RSA cipher suites,
to be cleaned up in a follow-up). Either way, we have the certificate
mismatch tests for this.

This is a really dumb API wart. Now that we have a limited set of curves that
are all reasonable, the automatic logic should just always kick in. This makes
set_ecdh_auto a no-op and, instead of making it the first choice, uses it as
the fallback behavior should none of the older curve selection APIs be used.
Currently, by default, server sockets can only use the plain RSA key exchange.

There's multiple sets of APIs for selecting the curve. Fold away
SSL_OP_SINGLE_ECDH_USE as failing to set it is either a no-op or a bug. With

key generation from then on being uniform. Also clean up the interaction
between the three API modes in s3_srvr.c; they were already mutually exclusive

tls1_process_sigalgs now only determines the intersection between the peer
algorithms and those configured locally. That list is queried later to
determine the hash algorithm to use when signing CertificateVerify or
ServerKeyExchange.
This is needed to support client auth on Windows where smartcards or CAPI may
not support all hash functions.
As a bonus, this does away with more connection-global state. This avoids the
current situation where digests are chosen before keys are known (for
CertificateVerify) or for slots that don't exist.

CERT_PKEY_SIGN isn't meaningful since, without strict mode, we always fall back

This finally removes the sensitivity between valid_flags and selecting the

It doesn't depend on the cipher now that export ciphers are gone. It need only
be called once. Also remove the valid bit; nothing ever reads it. Its output is
also only used within a function, so make mask_k and mask_a local variables.
So all the configuration-based checks are in one place, change the input
parameter from CERT to SSL and move the PSK and ECDHE checks to the mask
computation. This avoids having to evaluate the temporary EC key for each
cipher.
The remaining uses are on the client which uses them differently (disabled
features rather than enabled ones). Those too may as well be local variables,
so leave a TODO.

Server-side support was removed in 77a942b7fe,
but client-side support was retained as it appeared NSS supported this.
However, this is not the case: ssl3_HandleServerKeyExchange only allows a
ServerKeyExchange message if hs.ws is in an appropriate state.
ssl3_AuthCertificate only sets it to allow ServerKeyExchange if it is a key
exchange that normally uses it or if is_limited is set. is_limited is only set
for the export cipher suites.
Thus we can safely remove this without waiting on gathering UMA data.

This is the first of reorganizing state between connection state and 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
