1747fd1cc6 Add support for ECDH KARI.
Add support for ECDH in enveloped data. The CMS ctrls for the EC ASN1
method decode/encode the appropriate parameters from the CMS ASN1 data
and send appropriate data to the EC public key method.

9c37519b55 Improve optional 64-bit NIST-P224 implementation, and add NIST-P256 and
NIST-P521. (Now -DEC_NISTP_64_GCC_128 enables all three of these;
-DEC_NISTP224_64_GCC_128 no longer works.)

48ce525d16 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).

62e3163b1b ECPublicKey_set_octet_string and ECPublicKey_get_octet_string
behaviour was not quite consistent with the conventions
for d2i and i2d functions as far as handling of the 'out'
or 'in' pointer is concerned.

This patch changes this behaviour, and renames the functions to
o2i_ECPublicKey and i2o_ECPublicKey (not 'd2i' and 'i2d' because the
external encoding is just a raw object string without any DER icing).

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 :-)

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).
