  Fix a few bugs with the _gettemp() routine which implements mkstemp(),
  mkstemps(), and mkdtemp().
  - Add proper range checking for the 'slen' parameter passed to mkstemps().
  - Try all possible permutations of a template if a collision is encountered.
    Previously, once a single template character reached 'z', it would not wrap
    around to '0' and keep going until it encountered the original starting
    letter.  In the edge case that the randomly generated starting name used
    all 'z' characters, only that single name would be tried before giving up.
