Add set_group, set_public and set_private methods. An EC_KEY_METHOD can use
these to perform any appropriate operation when the key components are set,
such as caching data in some more convenient ENGINE specific format or
returning an error if the parameters are invalid or the operation is
not supported.

Add EC_KEY_METHOD. This is part of the EC revision and will make EC behave
more like other algorithms. Specifically:

EC_KEY_METHOD is part of EC_KEY.
It is part of ENGINE.
Default or key specific implementations can be provided to redirect some
or all operations.
