When a view is destroyed then the views of subsurfaces remain until the view
list is rebuilt for the next repaint.
During that time view->parent_view contains an invalid pointer and weston will
crash when it tries to access the view.
This happens for a surface with subsurfaces with views on two different outputs
with the ivi-shell:
When the surface is destroyed then the destroy handler of the ivi-shell
(shell_handle_surface_destroy()) may be called first. It will (indirectly)
destroy the view of the main surface with weston_view_destroy().
Next the surface destroy handler of the subsurfaces
(subsurface_handle_parent_destroy() is called. It will unmap the first view of
the subsurface. Here weston_surface_assign_output() is called which tries to
find the output of the second view and accesses the now invalid
view->parent_view in the process.
There are probably other ways to trigger similar crashes.
To avoid this, clear view->parent_view when the parent view is destroyed.

A config event with width == 0 or height == 0 from the shell is a hint
to the client to choose its own dimensions. Since X11 clients don't
support such hints we make a best guess by trying to use the last saved
dimensions or, as a fallback, the current dimensions.
This hint is mainly used by libweston/desktop shells when transitioning
to a normal state from maximized, fullscreen or after a resize [1].
Without support for this hint the aforementioned transition causes
xwayland surfaces to be configured to a 1x1 size.
To be able to use the last saved dimensions with xwayland surface, the
shell needs to first set the maximized/fullscreen state and only then
set the new size, which is currently the case for desktop-shell.
Otherwise, if the new size is set first, then the last saved dimensions
will be set to the fullscreen/maximized values and won't be useful when
restoring to a normal window size.
[1] Recently we've introduced ba82af938a87ff088b4aacff3b8ac1b6bb461be2
"desktop-shell: do not forget to reset pending config size after
resizes". As we were not handling the 0x0 size hint, resizing X
applications started to fail. This patch fixes that.

During interactive resizes, we progressively change the size of the
client surface and send config events with these sizes to the client.
After that, the toplevel->pending.size keeps the size of the last config
event that we've sent, i.e. the surface size after the resize is over.
Later, if the client spontaneously resize (by attaching a buffer with a
different size or setting the viewport destination, for instance), their
surface size will change, but toplevel->pending.size continues being
that old size from after the resize. If something happens and Weston
decides to send a config event, clients may re-allocate to that old
size, resulting in a sudden resize.
This does not happen when a client goes from fullscreen/maximized to
windowed mode because in such cases we are resetting
toplevel->pending.size to zero. So in the next config event that clients
receive they are allowed to attach buffers with the size that they
prefer.
So do the same after a resize: set the pending config size to zero.

Starting with commit 4cde507be6 "backend-drm: fix plane sorting" the
plane list will have a descending order of the planes rather than ascending.
This reversed order had the side-effect of exposing the fact that we
don't set-up a plane index when creating the drm_plane using the DRM
virtual API. Without settting a plane index for that drm_plane we
effectively overwrite the plane index which has the 0 (zero) entry.
This wasn't an issue before commit 4cde507be6 "backend-drm: fix
plane sorting" as it seems we never picked up that plane index as
being a suitable one due to the fact that those were assigned to primary
planes, but after that commit, the cursor plane will be one getting
the 0 (zero) plane index.
Finally, this would trip over because we attempt to place a (cursor)
view on a primary plane (where it would've normally be a cursor
plane) and we end up with no framebuffer ref.
This is fixed trivially by assigning a plane index, different than the
ones already created by create_spirtes().

cases because the primary plane is usually first and there is often only one

With the help of a newly introduced function, weston_desktop_surface_set_orientation(),
this patch adds missing tiled states from the xdg-shell protocol.
The orientation state is passed on as a bitmask enumeration flag, which the
shell can set, allowing multiple tiling states at once.
These new states are incorporated the same way as the others, retaining
the set state, but also avoiding sending new configure events if nothing
changed since previously acked data.

Changing the mode will destoy the GBM surface for the output. As a result all
corresponding BOs are deleted regardless of the drm_fb refcount.
While a commit is pending, the last_state may contain a reference to such a BO.
So delay the mode switch until the commit is finished and the reference is
release.

The README for the IVI-shell is completely outdated.
Update the documentation, add some more information on the IVI-shell use cases
and explain how to use and customize the IVI-shell. Also convert the file to rst
and move it to doc directory next to the kiosk-shell documentation.
