interrupts could be recursive since lapic_eoi() called before rti
...
so fast interrupts overflow the kernel stack
fix: cli() before lapic_eoi()

i think my cmpxchg use was wrong in acquire
...
nesting cli/sti: release shouldn't always enable interrupts
separate setup of lapic from starting of other cpus, so cpu() works earlier
flag to disable locking in console output
make locks work even when curproc==0
(still crashes in clock interrupt)
