Gamepad-specific API is a separtate input path from standard "remote"
service. Specifically it adds:
- openGamepad that creates a virtual input device with
gamepad-specific suport
- send gamepad keys
- send gamepad axis updates, which support joysticks, analog triggers
and HAT axis (as an alternative to DPAD buttons).
