better sleep management in cupsd.

backend/usb-unix.c:
  - print_device(): Set & clear connecting-to-device printer-state-reason.

backend/socket.c:
  - main(): Set & clear connecting-to-device printer-state-reason.

backend/lpd.c:
  - lpd_queue(): Set & clear connecting-to-device printer-state-reason.
  - Reformat conditional to allow editor brace matching.

backend/ipp.c:
  - main(): Set & clear connecting-to-device printer-state-reason.
  - compress_files(): Printf format warning.

  - cupsdUpdateSystemMonitor(): Add test for connecting-to-device when
looking at active printers.
