/*-
 * Computes the multiplicative inverse of x in the range
 * [1,EC_GROUP::order), where EC_GROUP::order is the cardinality of the
 * subgroup generated by the generator G:
 *
 *         res := x^(-1) (mod EC_GROUP::order).
 *
 * This function expects the following two conditions to hold:
 *  - the EC_GROUP order is prime, and
 *  - x is included in the range [1, EC_GROUP::order).
 *
 * This function returns 1 on success, 0 on error.
 *
 * If the EC_GROUP order is even, this function explicitly returns 0 as
 * an error.
 * In case any of the two conditions stated above is not satisfied,
 * the correctness of its output is not guaranteed, even if the return
 * value could still be 1 (as primality testing and a conditional modular
 * reduction round on the input can be omitted by the underlying
 * implementations for better SCA properties on regular input values).
