Remove unnecessary ifdefs for DRM_MODE_CONNECTOR_DSI, DRM_MODE_CONNECTOR_DPI.
They are both provided by libdrm and were introduced long before 2.4.83 (the
lowest version we currently support).

Since commit 28d26483 ("build: bump libdrm requirement to newer version
(2.4.83)"), all supported libdrm versions provide modifier formats,
atomic API and blob formats. Remove ifdef checks (HAVE_DRM_ADDFB2_MODIFIERS,
HAVE_DRM_ATOMIC, HAVE_DRM_FORMATS_BLOB) to improve the code and make it
simpler.

Mode change from mixed-mode to renderer-only means we should no longer
try to place views in HW planes (as we composite everything into the
primary plane) thus we should avoid that whenever that happens.
In the same time we need to be able to place in mixed-mode/renderer-only
mode the cursor view into the cursor plane (if one is available).
This patch adds a further check to skip plane assignment when disabling
overlay support (when we switch to renderer-only mode), when drivers do
not have atomic-modeset or it has been disabled intentionally.

Adds a further assert() to make sure we're not checking against invalid
values. This was seen in the wild when the kernel rejects the commit for
overlay resulting in a check for invalid zpos values.

when switching to mixed-mode of compositing
This way we avoid an (incorrect) duplicate check of zpos values. Also,
this would be needed because the renderer needs have the lowest zpos value
available as we don't (yet) properly support underlays, the primary
plane serves as our renderer.
Adds also a check to see if we try to assign a view to a plane with
a lower zpos value than the one assigned to the primary when switching
to mixed-mode of compositing.

This is necessary for the test harness to be able to execute the compositor
multiple times in the same process. As we never unload opened modules, the
first compositor iteration will leave them all loaded and following compositor
iterations will then have them already loaded.

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

As we avoid importing the buffer in the GPU, when attaching the buffer
we'll not have a valid image to retrieve it from, and as such we'll
avoid touching and setting the surface state shader.
This adds also 'direct_display' to the surface state and with it, sets the
surface state 'direct_display' member whenever the imported buffer will
have the direct-display member set.

Adds a new callback 'can_scanout_dmabuf' in weston_backend, which
can be set by the back-end do determine if the buffer supplied can be
imported directly by KMS.
This patch adds a wrapper over it, 'weston_compositor_dmabuf_can_scanout'
which is called before importing the dmabuf in the GPU if the
direct_display dmabuf is being set. If that's true and the check
failed, we refuse to create a wl_buffer.
This patch avoids importing in the GPU.

This comment was added in 230f3b1bf8 with the
intent that if we had an information table about pixel formats (which we do
have today), we could implement more sanity checks like ensuring that width
pixels fit into stride.
Daniel Vetter said on #dri-devel IRC recently:
< danvet> since userspace shouldn't look at stride for buffers with
modifiers, only pass it around unchanged
I asked for clarification. It was expected that userspace would not do any kind
of sanity checks as modifiers could change everything.
Let's remove the misleading code comment so that people don't get the idea of
adding more well-intended but ill-advised sanity checks. If more checks are
added, they must take the modifier into account, which the existing checks do
not do.
After 5 years, it is far too late to remove our existing sanity checks, but we
can attempt to not cause any more damage that would restrict what people can do
in the kernel.

In this manner we will allow views to reach the overlay (or underlays)
even if the damage tracking will detect that the new view will
occlude the view underneath it.
Renames occluded_region to planes_region, and uses occluded_region
to represent the region where we add each view's visible-and-opaque region.
Sprinkle some comments about each region.
Re-uses the view's clipped region to determine visible-and-opaque region
which is accumulated (for both renderer and HW planes cases) into
occluded_region. The current view's clipped_region is then checked against
occluded_region.

We can determine if the pixel format used by the clients buffer is
scan-out capable much sooner, so do it when constructing the zpos
candidate list. It also removes the checks in their respective
prepare_ functions.
Avoids the situation where we'd need to retrieve the DRM framebuffer each time
when checking the pixel format.

In order to better optimize view assignment to HW planes, we construct
an intermediary zpos candidate list which is used aggregate all suitable
planes for handling scan-out capable client buffers.
We go over it twice: once to construct it and once to pick-and-choose a
suitable plane based its highest zpos position.
In order to maintain the view order correctly we track current zpos
value being applied to the plane state and use it when trying to place
a view into a plane.
Pass the computed zpos value to be applied to the plane state.

This is based on the assumption that overlays are in between cursor and

Due to an error in driving GitLab, this commit erroneously contained the
entirety of !267 (zpos support in the KMS backend) squashed into one
single commit, pushed into master.
In order to keep the history clean, this is being reverted; a rebased
version of !267 with the clear individual commits which were already
present will be applied in its place.
This reverts commit 95e3b0deae.

timeline subscription
When subscribing over the command line to the 'timeline' scope we hit
the situation where we could emit a timeline message but without the
weston_output object being (fully) enabled. The timeline subscription
object requires to install its own callback on the 'destroy_signal' but
at that time, the 'destroy_signal' is not initialized.
This moves 'destroy_signal' initialization before timeline has a chance
to emit a timeline subscription message for that weston_output.
While at it, move also 'frame_signal' initialization before any function
call to keep them nicely organized.

New in version 6 are touch shape, touch orientation and axis source
wheel tilt. Weston doesn't support any of them yet but simply not
sending the new events and new enum value is sufficient to claim to
support this version.
Also bump the Wayland requirement to 1.17 to ensure both version 6 and 7
definitions are in the XML.
The reason for bumping to v6 without implementing the new features is
that we must support v7 to make use of struct ro_anonymous_file
introduced in the previous commit.
