Currently the frame event gets lost: The touch focus is removed in the 'up'
event. So the focus is gone when the frame event arrives so it is never sent to
the clients.

To avoid this, keep the touch focus until the frame is handled.

This has undergone a change to avoid an ABI break, so rather than
hooking up a pending_touch boolean in weston_touch, keep a local list of
weston_touch_devices and have a pending_touch with each device to check
upon.
