  Log:
  Move the "- 1" into the RQB_FFS(mask) macro itself so that
  implementations can provide a base zero ffs function if they wish.
  This changes
    #define RQB_FFS(mask) (ffs64(mask))
    foo = RQB_FFS(mask) - 1;
  to
    #define RQB_FFS(mask) (ffs64(mask) - 1)
    foo = RQB_FFS(mask);
  On some platforms we can get the "- 1" for free, eg: those that use the
  C code for ffs64().
