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.

kbapidapter.h
|
|
This class is a hack connecting the Keyboard and Keyboard layout classes
|
|
with the older and really bad Keyboard API. This class is intended to be
|
|
replaced by a real terminal driver working over /dev/tty descriptors.
