- 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

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.

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
as if Sun wrote all of this :-)

EC_GROUP_{set_generator,get_generator,get_order,get_cofactor} are
implemented directly in crypto/ec/ec_lib.c and not dispatched to
methods.

Also fix EC_GROUP_copy to copy the NID.

be implemented differently soon).
