Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.

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 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 cb76f1ea75 Kernel: Add some functionality to disable TTY input/output
Userspace programs can call tty_ctrl() to disable/enable tty from
handling input and displaying output.

This API is probably going to change in the future to ioctl calls
but I'm not sure how ioctl is used and what functionality should it
have. I decided to create whole new function and syscall for now.

Next I will expose framebuffer in /dev/fb0 and then I can start work
on graphical environment! :D
