This change updates 8a99cb29 to make the generation of (EC)DSA nonces
using the message digest the default. It also reverts the changes to
(EC)DSA_METHOD structure.

In addition to making it the default, removing the flag from EC_KEY
means that FIPS modules will no longer have an ABI mismatch.

This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

In EC_KEY_set_public_key_affine_coordinates include explicit check to see passed components do not exceed field order

the FIPS capable OpenSSL.

allow status of POST to be monitored and/or failures induced.

Move compression, point2oct and oct2point functions into separate files.

Add a flags field to EC_METHOD.

Add a flag EC_FLAGS_DEFAULT_OCT to use the default compession and oct
functions (all existing methods do this). This removes dependencies from
EC_METHOD while keeping original functionality.

NIST PKV tests.

seed to: this doesn't introduce any binary compatibility issues as the
function is only used internally.

The seed output is needed for FIPS 140-2 algorithm testing: the functionality
used to be in DSA_generate_parameters_ex() but was removed in OpenSSL 1.0.0

- hide the EC_KEY structure definition in ec_lcl.c + add
  some functions to use/access the EC_KEY fields
- change the way how method specific data (ecdsa/ecdh) is
  attached to a EC_KEY
- add ECDSA_sign_ex and ECDSA_do_sign_ex functions with
  additional parameters for pre-computed values
- rebuild libeay.num from 0.9.7

I've covered all the memset()s I felt safe modifying, but may have missed some.

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
