Kernel: Add timeout for device commands on PS/2 devices

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.

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.

Bootloader: Add support for ext2 blocks up to 4 KiB
...
This should work with blocks bigger than that, but my linux system
only supports up to 4 KiB, so I cannot test this.
This allows getting rid of forced block size in mkfs and let the
program select appropriately sized blocks.

Bochs int 0x10 seems to scrap full ebp and top bits in some

ebp is across all int 0x10 calls.

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.
