Apparently the initial interrupt count lapic[TICR]
...
must be set *after* initializing the lapic[TIMER] vector.
Doing this, we now get clock interrupts on cpu 1.
(No idea why we always got them on cpu 0.)
Don't write to TCCR - it is read-only.

Mainly delete unused constants and code.
Move mp_startthem to main.c as bootothers.

Clean up lapic code.
...
One initialization function now, not three.
Use #defines instead of enums (consistent with other code, but sigh).
Still boots in Bochs in SMP mode.

run without lapic and ioapic, if they are not present
...
if no lapic available, use 8253pit for clock
now xv6 runs both on qemu (uniprocessor) and bochs (uniprocessor and MP)
