xdg-shell: Specify the meaning of 0x0 window geometry in configure 

Some times the compositor needs to send a configure request but without
having any clue about what size the surface should have. Examples
include unmaximizing a surface that was mapped as maximized, or an
initial state which doesn't have any size expectations.

about how its surface should be resized in window geometry
coordinates. See set_window_geometry.
If the width or height arguments are zero, it means the client
should decide its own window dimension. This may happen when the
compositor need to configure the state of the surface but doesn't
have any information about any previous or expected dimension.
The states listed in the event specify how the width/height
arguments should be interpreted, and possibly how it should be
drawn.
