Kernel: Fix interrupt system
...
I had not understood how MSIs work and I was unnecessarily routing them
through IOAPIC. This is not necessary and should not be done :D
Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.

Kernel: Allow SYS_EXEC to fail at any point
...
This patch builds new executable image to another pml4 structure and
only after everything is validated will current context be replaced.
This allows exec to fail "late" where previously it would panic the
kernel or kill the process. This allows graceful handling of exec
failures in userspace!

Terminal: Do scrolling in putchar if necessary

I overlooked that handling *newline* scrolls would be enough. You can
definitely scroll more if printing a lot of text which wraps to the next
line.

This warning is only generated when compiling with UBSAN and I don't see

BuildSystem: Use -O2 for all libraries

I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.

Kernel: Allow parallel LAPIC timer initialization with HPET
...
HPET supports reading LAPIC counter without locks, so it can be done in
parallel. This makes booting much faster. Previously initializing every
timer took 100 ms, so 16 CPUs took total of 1.6 seconds. This allows
doing it all in 100 ms.

Also SYS_CREATE_DIR now uses correct relative path. It used to always
