This allows killing processes even when there does not exist a current
thread.

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
how the value would even be uninitialzed.

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.

Kernel: Perform access checks when creating a file or a directory
...
Also SYS_CREATE_DIR now uses correct relative path. It used to always
create files relative to root. And as no permission checks were tested,
file creation succeeded to root as long as path did not contain '/' :D

Kernel: Rework kernel-side ELF loading
...
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.
This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.

Kernel: Fix bugs in memory regions
...
MemoryRegion::initialize() required size to be page aligned, this is not
necessary.
MemoryBackedRegion::copy_data_to_region() required user-write
permissions for underlying data. This did not matter as memory backed
regions dont support COW memory, but it could lead to bugs later on.

1. only invalidate window once after rendering is done
2. if printing more than `rows()` newlines skip prior data
