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

Bananymous af4af1cae9 Kernel/LibC: add mmap for private anonymous mappings
This will be used by the userspace to get more memory. Currently
kernel handles all allocations, which is not preferable.

Bananymous 40055f023c LibC: add wait and waitpid
Note that wait() doesn't work since only waiting for specified
pid is supported. wait() will just return -1 and set errno to
ECHILD.
