   • 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
