f71c6e52f7 Add support for distinct certificate chains per key type and per SSL 
structure.

Before this the only way to add a custom chain was in the parent SSL_CTX
(which is shared by all key types and SSL structures) or rely on auto
chain building (which is performed on each handshake) from the trust store.
