Bananymous a5cb4057f9 Kernel: Implement unified input files for device hot-plugging support
/dev/keyboard and /dev/mouse can be read for events from any attached
keyboard or mouse respectively. This makes device hot-plugging support
pretty much automatic for TTY, GUI, and whatever takes input.

Bananymous 9d7f97ccd5 Kernel: Implement DevFileSystem::remove_device
This function cleanly removes the devices from the whole filesystem.

USB devices are now removed from the filesystem as soon as they are
destroyed.

Bananymous a97a574718 Kernel: Rewrite the whole input system
PS/2 code is now kind of messed up, but it works. Keyboards and mice are
now an abstract class that is automatically exposed to userspace. This
will make adding USB input much nicer.

Bananymous bce16cdd6e Kernel: Fix how socket closing works
Sockets are now closed only when they are not referenced any more. This
allows child process to close socket and still keep it open for the
parent.

Bananymous ea7fc7f6c4 Kernel: Implement read-only FAT12/16/32 driver with long name support
You can now mount FAT filesystems! This code might not work perfectly
but my quick testing seemed to work on all (FAT12/16/32) variants.

Bananymous 0af74fccda Kernel/LibC: Rework dirent structure
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

Bananymous 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.

Bananymous 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.

Bananymous fdb6dc94ba Kernel: cast between inheritance with static_cast
using reinterpret_cast is not a good idea. preferably we would use
dynamic_cast, but that is not possible since kernel is compiled with
-fno-rtti.

Bananymous fd18071975 Kernel: Implement TerminalDriver for Framebuffer device
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.
