Changes between 1.0.0b and 1.0.1 [xx XXX xxxx]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
*) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
elliptic curve NIST-P224 with constant-time single point multiplication on
typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
