[RFC PATCH 06/12] tablet-shell: Applications can run on tablet

From: Juan Zhao <juan.j.zhao at intel.com>

Add a event in tablet-client. When a client is connected to server, the
set_fullscreen event would be sent. and client will call shell_surface's
set_fullscreen method to be fullscreen.

Client application like dnd clickdot can run on tablet-shell.
listener is added in window.c and that can be moved to application side.
And simple-egl is still not sure how to resize the egl surface, so this
version can't run fullscreen.
