7eb18f1237 Simplify handling of named curves: get rid of EC_GROUP_new_by_name(), 
EC_GROUP_new_by_nid() should be enough.  This avoids a lot of
redundancy.

 - 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

14a7cfb32a use a generic EC_KEY structure (EC keys are not ECDSA specific)

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 :-)

5dbd3efce7 Replace 'ecdsaparam' commandline utility by 'ecparam' 
(the same keys can be used for ECC schemes other than ECDSA)
and add some new options.

Similarly, use string "EC PARAMETERS" instead of "ECDSA PARAMETERS"
in 'PEM' format.

Fix ec_asn1.c (take into account the desired conversion form).

b6db386ffd Change internals of the EC library so that the functions 
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.

4f69172d25 Completely remove mont2 stuff. 
It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).
