Log Message:
Refactor interval timers to make it possible to support types other than
the BSD/POSIX per-process timers:
- "struct ptimer" is split into "struct itimer" (common interval timer
data) and "struct ptimer" (per-process timer data, which contains a
"struct itimer").
- Introduce a new "struct itimer_ops" that supplies information about
the specific kind of interval timer, including it's processing
queue, the softint handle used to schedule processing, the function
to call when the timer fires (which adds it to the queue), and an
optional function to call when the CLOCK_REALTIME clock is changed by
a call to clock_settime() or settimeofday().
- Rename some fuctions to clearly identify what they're operating on
(ptimer vs itimer).
- Use kmem(9) to allocate ptimer-related structures, rather than having
dedicated pools for them.
