ecc: Add support for GOST R 34.10-2001/-2012 signatures
* src/cipher.h: define PUBKEY_FLAG_GOST
* cipher/ecc-curves.c: Add GOST2001-test and GOST2012-test curves
defined in standards. Typical applications would use either those
curves, or curves defined in RFC 4357 (will be added later).
* cipher/ecc.c (sign_gost, verify_gost): New.
(ecc_sign, ecc_verify): use sign_gost/verify_gost if PUBKEY_FLAG_GOST
is set.
(ecc_names): add "gost" for gost signatures.
* cipher/pubkey-util.c (_gcry_pk_util_parse_flaglist,
_gcry_pk_util_preparse_sigval): set PUBKEY_FLAG_GOST if gost flag
is present in s-exp.
* tests/benchmark.c (ecc_bench): also benchmark GOST signatures.
* tests/basic.c (check_pubkey): add two public keys from
GOST R 34.10-2012 standard.
(check_pubkey_sign_ecdsa): add two data sets to check gost signatures.
* tests/curves.c: correct N_CURVES as we now have 2 more curves.

Removed some comments from the new curve definitions in ecc-curves.c
to avoid line wrapping. Eventually we will develop a precompiler to
avoid parsing those hex strings. -wk
