Update the field returned by weston_head_get_display_info(). This makes
EDID di_info available to frontends.
Since EDID data has changed, then head device_changed must be true as
well, because di_info may expose all EDID information and not just what
we track in the backend.

This new public API is intended to deliver EDID etc. information to the
frontend. The use case here is display colorimetry, to help the frontend
craft output image descriptions (color profiles).
The frontend will need to link to and use libdisplay-info to make use of
this. This avoids having to replicate in libweston the high-level API
that libdisplay-info already has. The libdisplay-info API is also likely
to be extended, and it is not nice to play catch-up with it.
As a di_info can only be destroyed by calling into libdisplay-info,
libweston core can only ensure it has already been freed. There is not
enough reason to make libweston core depend on libdisplay-info, only the
DRM-backend is.
It will be up to DRM-backend to ensure display_info is updated and
device_changed is set only when necessary.

The #ifndef doesn't work with the built-in static_assert from C++11, so
it ends up getting redefined. It seems that there are other versions of
static_assert internally in some C++ standard library implementations
that have additional arguments, and these also get overwritten by the
two-argument version here.
Detect if we're using a suitably-recent version of C++ and avoid the
redefintion in that case.

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.

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

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.
