Cleanup of scheduler code

Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/

Small locking performance tweak.

Still better locking - does not hold global spinlock when
destroying cache.

Small fix in slab allocator for large-sized slabs.

Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems.

/kernel/trunk/generic/src/cpu/cpu.c
/kernel/trunk/generic/src/proc/scheduler.c

Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.

Added more granular locking to slab allocator and thus fix
hopefully last race condition.
/kernel/trunk/generic/include/mm/slab.h

Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.

Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.

Fix context_save, so that it works even with inlines disabled (-O0).
/kernel/trunk/generic/include/context.h

SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.
