Add an implementation of GOST 34.10-2001 as described in

draft-dolmatov-cryptocom-gost34102001-06

Known problem: GOST's X.509 (and PKCS #8?) formats are different from
ECDSA. ECDSA uses compressed points, GOST uses a completely raw pair
of points (with, OF COURSE, no leading uncompressed pair identifier,
because using something that already exists would just be too much).
