The GL renderer allows the PipeWire backend to allocate DMABUFs that can be used
as renderbuffers and passed to PipeWire. This allows to avoid a copy of the
rendered output when using PipeWire.
PipeWire negotiates DmaBuf buffers using the SPA_FORMAT_VIDEO_modifier property.
Currently, the PipeWire-backend only announces and handles
DRM_FORMAT_MOD_LINEAR, which allows to share DmaBufs with consumers that have
modifier support for linear buffers. Consumers which could consume DmaBufs but
don't support modifiers (DRM_FORMAT_MOD_INVALID) are not supported. Moreover,
consumers that would benefit from other formats with modifiers, for example
tiled or compressed, aren't not supported, too.
Modifier negotiation can be added by extending the list of announced modifiers
and selecting and checking the proposed modifiers in param_changed.

Instead of letting PipeWire allocate the buffers, allocate them in the PipeWire
backend. This allows the PipeWire backend to define the type of the allocated
buffers, which will ultimately allow to allocate buffers that can be rendered
to.

Support importing dmabuf buffers as renderbuffers and binding them to
FBOs. These can then be rendered to directly, or they can be blitted
into from the shadow render buffer.
How to best create those dmabuf buffers in the backend is an open

interfacing with.

The GL renderer uses the bottom left corner as origin. Therefore, the buffers
must be flipped when using ReadPixels to have a image in the correct orientation
for screenshots. If the rendered buffers are directly passed to a different
application without going through ReadPixels, the rendered buffer appears upside
down.
Flip the rendered image in the FBO to fix the orientation when directly using
the rendered buffer. Update read_pixels to not flip the image in these cases.

1. remove the restriction on underlay planes when finding plane.
Because the view on the underlay plane can be displayed by drawing
a through hole on primary plane, so we can try underlay planes.
2. Add step to check if the view is assigned on underlay plane, When
it is successfully placed on a HW plane. Because we need to set the
underlay view pnode->need_hole to true so that gl-renderer
will draw a hole for it when repainting.
3. Avoid assigning views to underlay HW planes when the backend format
is opaque and avoid assigning views with alpha to underlay HW planes.
4. when overlay plane is not enough, try to find underlay plane on
platform with both overlay and underlay plane.

On underlay platforms, the HW planes can be placed below the primary
plane, so some views that intersect with the renderer region can try
to be placed on the underlay planes. In order to assign these views
to underlay planes, the improvement is as follows:
1. Add current_lowest_zpos_overlay. Record the current lowest zpos
of the overlay planes.
2. Add current_lowest_zpos_underlay. Record the current lowest zpos
of the underlay plane. It is initialized to scanout_plane::zpos.
3. Add need_underlay to indicate whether to find underlay plane for
view.
4. The views that intersect with the renderer region and underlay
views should be assigned to underlay planes.

This reverts f843ba34d1 ("drm-backend: limit
reset/restart to output of a failed commit") and actually solves the problem
correctly.
The pending_state is no longer valid at this point, so it cannot be used to
determine the outputs of the current commit. So only clear will_repaint when
starting to repaint, so it can be used to determine which outputs of a device
were actually repainted and use it to reset/restart those outputs.

This prevents a potential abort yelling:

which happens because we never unregister the output, a mirror function
for nvnc_add_display().
Further more, we migrate nvc_close() to vnc_destroy() and check for
a valid output in vnc_client_cleanup(). Having a single caller in
vnc_shutdown() (which was migrated) we removed that entirely. Necessary
to avoid a use-after-free caused by nvc_close().

After c08a6ff8 moved attach to the render loop, we have a bad situation
when clients delete an attached shm buffer. We try to query the stride
at attach time, but the shm_buffer has been destroyed, and we crash.
Instead of carefully fixing that, I've instead stored the stride at
buffer creation time (as we already do with buffer width and height).
This lets attach succeed in the gl-renderer, keeping the old texture data
available for any upcoming rendering.
