Add ECDH support.
Additional changes:
- use EC_GROUP_get_degree() in apps/req.c
- add ECDSA and ECDH to apps/speed.c
- adds support for EC curves over binary fields to ECDSA
- new function EC_KEY_up_ref() in crypto/ec/ec_key.c
- reorganize crypto/ecdsa/ecdsatest.c
- add engine support for ECDH
- fix a few bugs in ECDSA engine support
