[PATCH 4/7] compositor: add a way to disable picking of client surfaces

[Ander Conselvan de Oliveira]

Surfaces like drag'n'drop icons shouldn't receive events as a normal
surface but are still created by the client so add a way for the
compositor to enable or disable the picking of a client surface.
