New 64-bit optimized implementation EC_GFp_nistp224_method().
...
Binary compatibility is not affected as this will only be
compiled in if explicitly requested (#ifdef EC_NISTP224_64_GCC_128).

ecc api cleanup; summary:
...
- 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

Deprecate the recursive includes of bn.h from various API headers (asn1.h,
...
dh.h, dsa.h, ec.h, ecdh.h, ecdsa.h, rsa.h), as the opaque bignum types are
already declared in ossl_typ.h. Add explicit includes for bn.h in those C
files that need access to structure internals or API functions+macros.

Allow EC_GROUP objects to share precomputation for improved memory
...
efficiency (EC_PRE_COMP objects are now constant once completed).
Extend 'extra_data' API to support arbitrarily many slots (although we
need only one at the moment).
Modify EC internal 'extra_data' API: EC_GROUP_[clear_]free_extra_data
now frees only a single slot (the previous functions are available as
EC_GROUP_[clear_]free_all_extra_data).

the new method names where _GF... suffixes have been removed.
Revert changes to ..._{get/set}_Jprojective_coordinates_...:
The current implementation for ECC over binary fields does not use
projective coordinates, and if it did, it would not use Jacobian
projective coordinates; so it's OK to use the ..._GFp prefix for all
this.
Add author attributions to some files so that it doesn't look
