Werner Almesberger bcd3691c8a The Great ATSPI Renaming, part 6: change atrf API from atspi_* to atrf_*
- include/atrf.h, lib/atrf.c (struct atspi_dsc): renamed to "struct
  atrf_dsc"
- include/atrf.h, lib/atrf.c (atspi_*): renamed all functions to atrf_*
- include/misctxrx.h, lib/misctxrx.c (wait_for_interrupt): updated for API
  name change
- atspi-id/atspi-id.c (show_usb_info, show_info, main),
  atspi-reset/atspi-reset.c (main), atspi-rssi/atspi-rssi.c (sweep, main),
  atspi-rssi/gui.h (gui), atspi-rssi/gui.c (sweep, gui),
  atspi-trim/atspi-trim.c (main), atspi-txrx/atspi-txrx.c (init_txrx,
  set_channel, set_power, receive, transmit, test_mode, main):
