sortix--sortix/sortix/keyboard.h
Jonas 'Sortie' Termansen ead0e1523f Refactored the kernel keyboard API, but kept system calls compatible.
Caps lock now works as caps lock, not as shift lock.

This new design will allow implementing a working tty, such that stdin is
the only way to access the keyboard, instead of the current hacky way of
using a special system call to read from the keyboard.

Added a new system header file <sys/keycodes.h> defining the constants for
every key on the keyboard. This will be used in future APIs.

The main change is to split the keyboard driver into a class that reads
from the keyboard, while another class handles the translation into
printable characters (if possible). This allows a terminal driver based
on logical key presses and printable characters, instead of a terminal
driver based only on unicode-ish codes.
