Don't allocate a structure to handle ECC extensions when it is used for
default values.

Make supported curves configurable.

Add ctrls to retrieve shared curves: not fully integrated with rest of
ECC code yet.

ecparam utility and ECC method to recognise the NIST names for curves.

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.
