Unexport EC_METHOD and all API using it

This is an implementation detail and there is no reason to leak it from
the library.

This removes EC_GFp_{mont,simple}_method(), EC_GROUP_{method_of,new}(),
EC_METHOD_get_field_type(), EC_POINT_method_of() from the public API.

EC_GROUP_copy() is now quite useless, so it will go as well.

ok jsing
