[PATCH weston 2/6] input: Use a client id indexed array for input device resources

From: Rob Bradford <rob at linux.intel.com>
Replace the list of resources per pointer/keyboard/touch with an array
of pointers to lists of resources from that client.
For compatability with the existing code find_resource_for_surface has
been modified to return the resource associated with the first entry in
the list and this is used to fill the focussed resource member on
pointer, keyboard and touch.
