 * Replacement implementation of getopt.
 *
 * This is a replacement implementation for getopt based on the my_getopt
 * distribution by Benjamin Sittler.  Only the getopt interface is included,
 * since remctl doesn't use GNU long options, and the code has been rearranged
 * and reworked somewhat to fit with the remctl coding style.
