<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks for the patch - there's a few other kqueue related issues floating around out there that this patch may help address.
I didn't review this for correctness, merely for coding guideline violations. Assuming someone else who can run res_timing_kqueue can confirm that it works and that the tests pass, I'll be happy to Ship It! once the guidelines are cleaned up.</pre>

This fixes issues with using the kqueue timing source on Asterisk 13
on FreeBSD 10.
res_timing_kqueue.c:
Remove support for kevent64(). The values used to support Asterisk
timers fit within 32bits and so can be handled on all platforms via
kevent().
Provide debug logging for, but do not track, unacked events. This
matches the behavior of all other timer implementations.
Implement continuous mode by triggering and leaving active, a user
event. This ensures that the file descriptor for the timer returns
immediately from poll(), without placing the load of a high speed
timer on the kernel.
In kqueue_timer_get_max_rate(), don't overstate the capability of
the timer. On some platforms, UINT_MAX is greater than INTPTR_MAX,
the largest integer type kqueue supports for timers.
In kqueue_timer_get_event(), assume the caller woke up from poll()
and just return the mode the timer is currently in. This matches
all other timer implementations.
Adjust the test code now that unacked events are not tracked.</pre>
