asterisk port tweaks:

- use getthrid to record TID (this is displayed following the opaque thread
id in "core show threads", and is useful to match against top -H output)

- provide a -kqueue package for res_timing_kqueue (previously @comment'ed
out). Normally a pthread-backed timer is used in the package; the kqueue-backed
timer is built by default but has had problems on OpenBSD in the past so is
@comment'ed out. I wouldn't consider this production ready on OpenBSD (lots
of "kqueue_timer_ack: [18]: Missed 1" at least on a kernel with standard HZ)
but I'd like to have it more easily available for experimentation, hence
adding the package.

+kqueue-backed timer module for Asterisk.
+
+Timing is a fundamental part of Asterisk. It has multiple timing
+modules available for various OS. For OpenBSD, the options are pthread or
+kqueue-backed timers.
+
+Normally, the pthread-backed timer performs best, and this is included
+in the main package.
+
+This package provides the kqueue timer to make it easier for those
+wishing to EXPERIMENT with it (possibly on a kernel built with a higher
+HZ value).
+
+Use the "timing test" cli command to investigate performance.
