Kernel: All processors use LAPIC timer when running with APIC
...
This makes scheduler preemption much cleaner as bsb does not have to
send smp messages to notify other processes about timer interrupt.
Also PIT percision is now "full" 0.8 us instead of 1 ms that I was using
before.

Kernel: Implement API for sending IPIs for only one processor
...
Also move the spin wait to check for pending IPI sends to the start of
ipi sending function. There is no need to wait for IPI send succeeding
right after it. It is enough to make sure there are not multiple IPIs
being sent at the same time.

Kernel: Rework interrupt mechanism
...
All interruptrable classes now inherit from Interruptable which
has methdo handle_irq which is called on a interrupt.

Kernel: rework the whole PageTable structure

We now have page table structure for kernel memory which is shared
between all processes.

All: rename every function from UpperCamelCase to snake_case
...
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

Kernel: Add actual register values to x86_64 kernel panic
...
Very hackish implementation, but we now get actual registers at the
time of the interrupt happening

Kernel: Replace PIC with APIC

If APIC/IOAPIC is not found, we fallback to PIC
Interrupts don't seem to work on real hardware (?)
