* remotes/kraxel/tags/pull-input-20160928-1:
  ps2: do not generate invalid key codes for unknown keys
  ps2: use QEMU qcodes instead of scancodes
  ps2: allow keycode translation for all scancode sets
  ps2: correctly handle 'get/set scancode' command
  ps2: reject unknown commands, instead of blindly accepting them
