From: Quentin Glidic <sardemff7+...@sardemff7.net>
This fixes a race between Xwayland committing the surface content via
the wl_surface, and the XWM setting the role of the surface.
We now keep track of the (first) content commit on the surface and
forward it to the shell when we finally get the role.
There is no need to track later changes, as the only way for Xwayland to
unmap a surface is to destroy it.
