Map Touchscreen to Output: Allow clients to configure a relation between touchscreen and display outputs
When configured the touch contact coordinates will be mapped into the screen space occupied by the output. Previously the first output was used as default and orientation information was ignored. This default behavior is still in place - when not configured the builtin output on android devices will be used. Additionally the connection between input devices and outputs is used to disable input events from deactivated outputs. Fixes: https://bugs.launchpad.net/bugs/1349660.
