Currently, if a head is detached, the entire state of the device is invalidated
to make sure that the connector is disabled on the next atomic commit. Side
effect of the invalid state is that all planes are disabled on the next commit.
This includes planes that are used with a different head that is not part of the
next atomic commit. Disabling the planes of unrelated outputs causes a blanking
of these outputs until output is repainted and the plane is reenabled.
Store the detached heads in a list on the output and disable the connectors for
all heads in this list in the next atomic commit.

The assumption that a previously unmapped view is valid already leads to the

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.

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().

As things are, even when mode=current is specified on the .ini file,

The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

Surface views that are not assigned to a layer are not going to be
rendered, and thus should not participate in determining the outputs the
surface is on.
There are other view properties that may determine if the view should be

for this currently breaks tests. Such additional checks are left for
future fixes or reworkings of the view infrastructure.

The planes in the plane_list must be sorted from largest zpos_max to smallest.
Currently the plane order is only correct when the planes are already ordered
and added starting with the smallest zpos_max. This works accidentally in most
cases because the primary plane is usually first and there is often only one
overlay plane or the zpos is sufficiantly configurable.
To fix this, insert a new plane before the first plane with a smaller zpos_max.
And if none is found, insert it at the end of the list.

When an atomic commit fails then the output will be stuck in
REPAINT_AWAITING_COMPLETION state. It is waiting for a vblank event that was
never scheduled.
If the error is EBUSY then it can be expected to be a transient error. So
propagate the error and schedule a new repaint in the core compositor.
This is necessary because there are some circumstances when the commit can fail
unexpectedly:
- With 'state_invalid == true' one commit will disable all planes. If another
commit for a different output is triggered immediately afterwards, then this
commit can temporarily fail with EBUSY because it tries to use the same
planes.
- At least with i915, if one commit enables an output then a second commit for a
different output immediately afterwards can temporarily fail with EBUSY. This
is probably caused by some hardware interdependency.

As wayland-backend is blitting the output decorations into the output
buffer itself, it pretends towards the pixman-renderer that there is no
decorations area. The pixman_image_create_bits() call wraps the
previously allocated buffer with an offset so that pixman-renderer will
paint in the right position.
The bug is that this pixman image was using the original buffer width
and height, instead of the composited area width and height. So the
pixman image looks too big to pixman-renderer, but the renderer didn't
care. The image being too big does risk access out of bounds in
pixman-renderer.
I found this when I was making renderers explicitly aware of the
frambuffer size and resizing, added asserts, and they surprisingly
failed. This fixes that.

Everywhere we are standardising to drm_fourcc.h pixel format codes, and

standardisation, convert weston_compositor::read_format to
pixel_format_info.
Pixman formats are defined CPU-endian, while DRM formats are defined
always little-endian. OpenGL has various definitions. Correctly mapping
between these when the CPU is big-endian is an extra chore we can
hopefully offload to pixel-formats.c.
GL-renderer read_format is still defined based on Pixman format, because
of the pecualiar way OpenGL defines a pixel format with
GL_UNSIGNED_BYTE. That matches the same Pixman format on big-endian but
not the same drm_fourcc.

When an output is destroyed then the output state is freed immediately. In this
case, the plane state is only partially destroyed because it is the currently
active state. This includes the buffer reference.
Without the output, the plane will not be updated any more until it is used by a
different output (if possible) or the output returns and the plane is used
again.
As a result, the buffer reference is kept for a long time. This will cause some
applications to stall because weston now keeps two buffers (the one here and
another one for a different output where the application is now displayed).
To avoid this, do a synchronous commit that disables the output. The output
needs to be disabled anyways and this way the current state contains no
buffers that would remain.
`device->state_invalid = true` in drm_output_detach_crtc() is no longer
needed, because drm_output_detach_crtc() is called only when initialization
failed and the crtc was not yet used or in drm_output_deinit() when the
crtc was already disabled with the new synchronous commit.
