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
primary plane and it is required to be able to assign views to planes,
even if the driver doesn't not expose such property.
As we hard-code them as immutable the commit part would not need any
further modifications.

Functional no change, as nobody makes use of it. Only apply the zpos

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.

We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

An object based on 'weston_timeline_subscription' will be created for
each subscription created. It contains the next object ID and list of
'weston_timeline_subscription_object'.
It will automatically be cleaned by the logging framework when the
subscription gets destroyed, or use the object destroy signal to trigger
the destruction of the timeline subscription (@pq), when the object
itself is being destroyed.
This class will hanged-off the subscription, such that we can
retrieve it when going over all the subscriptions.
An object based on 'weston_timeline_subscription_object' will help
maintain the state of the objects seen and will be created when a new
object will be emitted for a particular 'weston_timeline_subscription'.
Adds wrappers for ensuring the timeline subscription object is created
or has to be searched in order to be found, as to avoid duplicated code.

Rather than try to be clever in invoking weston_layer_set_mask, just build the
maximal mask explicitly.
weston_compositor_build_view_list can reconstruct the view_list without a view which was
previously in it. The existing pointers in view->link are left unchanged, which could
lead to corruption or access to released memory in wl_list_remove, depending of the
order of destruction of the views.
This can happen at least with the black view created by the desktop shell for fullscreen
surfaces, when it is hidden in lower_fullscreen_layer.

Use the surfaceless platform in the headless backend to initialize the
GL-renderer and create pbuffer outputs. This allows headless backend to use
GL-renderer, even hardware accelerated.

Since the RDP backend allocates regular memory already as hw buffer
anyway, a shadow buffer is not required. The read_pixels interface
anyway renders directly into the hardware buffer, hence this does
not make a performance difference in practise. It avoids allocating
an unnecessary buffer.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
When all shared/ headers are included in the same way, we can drop unnecessary
include seach paths from the compiler.
This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.
The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'
