Implement seatop_touch

Atm we got issue with the touch position sent to the clients. While
holding contact, leaving the initial container will continue to send
motion event to the client but with the new local position from the new
container.

This seatop goal is to send the position of the touch event, relatively
to the initial container layout position.
