This adds a new API, SSL_set_private_key_method, which allows the consumer to
customize private key operations. For simplicity, it is incompatible with the
multiple slots feature (which will hopefully go away) but does not, for now,
break it.
The new method is only routed up for the client for now. The server will
require a decrypt hook as well for the plain RSA key exchange.

To account for the changes in ticket renewal, Chromium will need to listen for
new_session_cb to determine whether the handshake produced a new session.
Chromium currently never caches sessions produced on a renegotiation. To retain
that behavior, it'll need to know whether new_session_cb is initial or not.
Rather than maintain duplicate state and listen for SSL_HANDSHAKE_DONE, it's
simpler to just let it query ssl->s3->initial_handshake_complete.

Platform crypto APIs for PKCS#1 RSA signatures vary between expecting the
caller to prepend the DigestInfo prefix (RSA_sign_raw) and prepending it
internally (RSA_sign). Currently, Chromium implements sign or sign_raw as
appropriate. To avoid needing both variants, the new asynchronous methods will
only expose the higher-level one, sign.
To satisfy ports which previously implemented sign_raw, expose the DigestInfo
prefix as a utility function.

Rather than write a dup function, serializing and deserializing the object is
simpler. It also fixes a bug in the original fix where it never calls
new_session_cb to store the new session (for clients which use that callback;
how clients should handle the session cache is much less clear).
The old session isn't pruned as we haven't processed the Finished message yet.
RFC 5077 says:
The server MUST NOT assume that the client actually received the updated
ticket until it successfully verifies the client's Finished message.
Moreover, because network messages are asynchronous, a new SSL connection may
have began just before the client received the new ticket, so any such servers
are broken regardless.

strangely, is only done for ECDSA ciphers.
