50e735f9e5 Re-align some comments after running the reformat script. 
This should be a one off operation (subsequent invokation of the
script should not move them)

dbd87ffc21 indent has problems with comments that are on the right hand side of a line. 
Sometimes it fails to format them very well, and sometimes it corrupts them!
This commit moves some particularly problematic ones.

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.

8a99cb29d1 Add secure DSA nonce flag. 
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.

-DEC_NISTP224_64_GCC_128 no longer works.)

84b08eee4b Reorganise ECC code for inclusion in FIPS module. 
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.

198ce9a611 Add additional parameter to dsa_builtin_paramgen to output the generated 
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

9dd8405341 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

ba729265a8 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).

35b73a1f20 Rename implementations of method functions so that they match 
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 :-)
