Werner Almesberger b4a6e8ef46 tools/: major overhaul of wait_for_interrupt; uses atrf_interrupt_wait now
- include/misctxrx.h (wait_for_interrupt), lib/misctxrx.c
  (wait_for_interrupt): replaced sleep_us*timeout limiting mechanism
  with a single timeout value in milliseconds
- lib/misctxrx.c (wait_for_interrupt): use atrf_interrupt_wait instead
  of polling
- lib/misctxrx.c (wait_for_interrupt): cleaned up control flow
- lib/misctxrx.c (run, die, wait_for_interrupt): renamed variable "run"
  to more specific "sigint"
- atrf-txrx/atrf-txrx.c (ping_rx, ping): pass timeout in milliseconds,
  not deciseconds
- atrf-rssi/atrf-rssi.c (sweep), atrf-rssi/gui.c (sweep),
  atrf-txrx/atrf-txrx.c (init_txrx, receive_message, receive_pcap,
  receive, transmit, transmit_pattern, ping_tx, ping_rx),
  atrf-xmit/atrf-xmit.c (init_tx, init_rx, xfer_one),
  lib/cwtest.c (enter_test_mode_230, start_test_mode_231):
  updated use of wait_for_interrupt
