- Major cleanup of USB keyboard driver:

Browse source 
* Remove huge hack, which is not needed anymore since 39912.
 * Put all global variables into device extension, allowing support for more than one USB keyboard.
 * Cleanup driver extension structure.
 * Remove unneeded endpoint finding code.
- Add test code for LEDs support (now puts three of them into ON state).
