Cleanup XXXdir functions to eliminate global hash table of

telldir positions.  This will allow (future) locking on a
per-DIR basis (for MT-safety).  For now, this change does
the following:

  o Remove the hash table from telldir.c.  Recode to use queue
    macros.

  o Remove 'const' from 'telldir(const DIR *)'.

  o Remove 'register' variables as suggested in a recent
    thread.
