Qt/EL mouse and keyboard driver cleanup.

 * removed the vr41xx, yopy and sl5000 drivers (old PDAs)
 * removed the bus mouse driver (ISA days should be over)
 * renamed the LinuxIS mouse driver to LinuxInput (consistency with the key driver)
 * unified the LinuxInput mouse and key driver I/O handling
