Document SSL_get_extms_support().

Modify behaviour of SSL_get_extms_support() so it returns -1 if the
master secret support of the peer is not known (e.g. handshake in progress).

Update master secret calculation to support extended master secret.
TLS 1.2 client authentication adds a complication because we need to
cache the handshake messages. This is simpllified however because
the point at which the handshake hashes are calculated for extended
master secret is identical to that required for TLS 1.2 client
authentication (immediately after client key exchange which is also
immediately before certificate verify).

Add and retrieve extended master secret extension, setting the flag
SSL_SESS_FLAG_EXTMS appropriately.

Note: this just sets the flag and doesn't include the changes to
master secret generation.

Rewrite ssl3_send_client_key_exchange to retain the premaster secret
instead of using it immediately.

This is needed because the premaster secret is used after the client key
exchange message has been sent to compute the extended master secret.
