db933d5466 Kernel: Improve keymap file loading 
Now you can include other files in keymaps and set which keys are
modifier keys

Only keys that are set in keymap file are actually updated

83ca469ed7 Kernel: Modifier keys are taken from current keyboard layout 
I used to assume where all modifiers were, but they are now taken
from keyboard layout.

961ab9768a Kernel: KeyEvent is now well known keycode 
Keycodes are easier to handle as you need only one keyboard layout
for keycodes. Otherwise you would need to implement keyboard layout
for every keyboard driver in every language.

d760239748 Kernel: Do a big rewrite of PS/2 code 
Command sending+response reading is now synchronized. This allows
bochs to properly initialize both mouse and keyboard simultaneously.

Also status register is checked EVERY time read/write to other IO
ports is performed.

extra buttons) from mouse and reads mouse packages.

d2d12d5281 Kernel: validate_{string,pointer}_access now return ErrorOr<void> 
Now that signals are only processed when returning to userspace,
address validation has to do an early return.

001e95f973 Kernel: Optimize sse saving/loading 
Only save and load sse when new thread is trying to execute sse
instruction. There is no need to do that every time we enter kernel.

9fa13079f2 Kernel: Implement supplementary groups 
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...

This allows users to open framebuffer/input files without root.

Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

2e858fddb5 Kernel: Remove obsolete Scheduler::is_valid_tid() 
This function was used when processes could die at any point in time.
Now that processes can only die in known spots, we can be sure they
are not holding any locks. This allows much more performant locking.

1c78671078 Kernel: Rework all signal code 
Signal handling code was way too complex. Now everything is
simplified and there is no need for ThreadBlockers.

Only complication that this patch includes is that blocking syscalls
have to manually be made interruptable by signal. There might be some
clever solution to combat this is make this happen automatically.
