tools/: the great removal of atrf_interrupt

- atrf-proxy/PROTOCOL, atrf-proxy/atrf-proxy.c (cmd_zero): removed the
  POLL command
- lib/atben.c (atben_driver): don't export atben_interrupt anymore (we
  still use it internally)
- lib/atnet.c (atnet_interrupt, atnet_driver): removed atnet_interrupt
- lib/atusb-common.h (atusb_interrupt), lib/atusb-common.h
  (atusb_interrupt), lib/atusb-spi.c (atusb_spi_driver),
  lib/atusb.c (atusb_driver): removed atusb_interrupt
- lib/driver.h (struct atrf_driver): removed "interrupt"
- include/atrf.h (atrf_interrupt), lib/atrf.c (atrf_interrupt): removed
