All vectors were tested against libsecp256k1, and all verification vectors were checked against OpenSSL. A check was also added to the verify specification to reject pubkeys with x or y coordinates greater than or equal to p, but output on valid input is unchanged.

See #2224.

BIP461: add test vectors and reference implementation

All vectors were tested against libsecp256k1, and
all verification vectors were checked against OpenSSL.
A check was also added to the `verify` specification
to reject pubkeys with x or y coordinates greater than
or equal to `p`.
