tools/: added interrupt_wait support to atnet and atrf-proxy (untested)
- atrf-proxy/PROTOCOL: WAIT is now implemented and takes a timeout argument - atrf-proxy/atrf-proxy.c (cmd_more): implemented WAIT command using atrf_interrupt_wait - lib/atnet.c (atnet_interrupt_wait, atnet_driver): added interrupt_wait (using WAIT)

The WAIT command is not answered until an interrupt or another command is

received. WAIT returns the interrupt status, just like POLL.

received. WAIT returns the value of the IRQ_STATUS register. If WAIT
|

times out before receiving an interrupt, it returns 0.
