ECC private keys had two different constructors, one taking a group

and a random number generator, and the other taking a group and a
preset private key value. The DL private keys instead have on
constructor for this; if the x value is zero, then a new random key is
created. For consistency, do this with ECC as well.

ECDH actually didn't have one of these constructors, forcing you to
either load from PKCS #8 or else use a random key.

Rename EC_Domain_Params to EC_Group, with a typedef for compatability.
