ca567a03ad Fix overly lenient comparisons: 
- EC_GROUP_cmp shouldn't consider curves equal just because
      the curve name is the same. (They really *should* be the same
      in this case, but there's an EC_GROUP_set_curve_name API,
      which could be misused.)

    - EC_POINT_cmp shouldn't return 0 for ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED
      or EC_R_INCOMPATIBLE_OBJECTS errors because in a cmp API, 0 indicates
      equality (not an error).

same structure is used by DH and ECDH.

190c615d43 Make `safe' (EC)DSA nonces the default. 
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.
