09ca4f32e2 secp256k1_fe_sqrt checks for success 
- secp256k1_fe_sqrt now checks that the value it calculated is actually a square root.
- Add return values to secp256k1_fe_sqrt and secp256k1_ge_set_xo.
- Callers of secp256k1_ge_set_xo can use return value instead of explicit validity checks
- Add random value tests for secp256k1_fe_sqrt

ba8fc0e28f Check signature nonces for validity 
The documentation implies that this check is happening, so make it so.
Without this check, passing an invalid nonce will trigger an internal assertion.
