Kernel: Implement SpinLock without CriticalScope
...
This actually is not even spinlock since it yields the current
thread. It will become one when I get to SMP though...

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

I used to assume where all modifiers were, but they are now taken
from keyboard layout.

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.

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.

This is realtively simple driver that queries extensions (scroll +
extra buttons) from mouse and reads mouse packages.

Now that signals are only processed when returning to userspace,
address validation has to do an early return.

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.

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.
