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.

Refactored the system to use the new Terminal interface. This will allow development of a better terminal providing stdin. Added new system calls settermmode(2) and gettermmode(2) declared in <sys/termmode.h>. They allow querying and changing the current mode of terminals (enabling raw keyboard data, signal handling, line buffering, UTF-8 encoding stdin, and more). However, all that is unsupported by the current terminal device driver. Added KBKEY_ENCODE and KBKEY_DECODE macros to <sys/keycodes.h> which allows encoding the kbkey format in UTF-32 characters.
