Bananymous 79851394b3 Kernel/LibC/Userspace: Add SYS_POWEROFF + cli tool
You can now shutdown/reboot banan-os with the poweroff cli tool.

Reboot doesn't seem to work on qemu.

Bananymous 8d5369fafe 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 fee3677fb9 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 9e4a87021c Kernel: Fix directory permissions
We did not care about X bit in directories and instead used only the
R bit for search/read.

Bananymous cbb9f47ee5 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.
