I was actually not disabling system timer (HPET, PIT) when using lapic
timers for scheduling. This made BSB get too many timer interrupts :D

Kernel: Optimize AML interpreter stack usage

There is a very hacky no-inline hack that I am not proud of but it drops
the stack usage of few functions A LOT.
Previously Virtual Box could not boot with our 8 page stack, but these
changes allow it to boot on 5!

Kernel: Remove kernel processes

Kernel can just use raw threads, pretty muchs the only thing that
process provides is syscalls which kernel threads of course don't
need.
Also this makes init process have pid 1 :D

Kernel: Increase PS2 timeout to 300 ms, load PS2 in separate thread
...
PS/2 seems to hit command timeout sometimes on slow emulation so
increase the timeouts.
Also move PS/2 device initialization to a different thread because
device indentification waits for timeouts.

Kernel: Rewrite ThreadBlocker
...
This gets rid of a very old bug where kernel panics when thread is being
woken up and unblocked at the same time on different cores. This
required adding a new lock to SchedulerQueue::Node and adding a cap to
how many threads a threadblocker can simultaneously block. I don't think
I ever block more than five threads on the same ThreadBlocker so this
should be fine.
