struct weston_test_surface in the test harness' compositor plugin had no
tear down code, which lead to ASan report on alpha-blending test:
Direct leak of 64 byte(s) in 2 object(s) allocated from:

While at it, let's do this properly for once:
- put the creation in a new function
- hook up to the weston_surface destroy signal so this actually gets
freed (fixes the leak)
- check that we don't overwrite another surface role
- check that committed_private actually is ours
- set the surface label func so it gets properly listed in debugs and
traces
- use the proper surface role setup call, so no-one stomps on anyones
toes if a test makes a mistake by using a wrong wl_surface

This new function is callable explicitly, unlike the old function that
used to have the same name.
This will be needed when tearing down what
weston_desktop_xwayland_init() puts up.
Since calling weston_desktop_client_destroy() for an external client
(one that has a wl_resource for this) is a bug, add asserts to prevent
it. This will only be needed for the internal client: XWM.

This function here is a wl_resource destructor, but we will need another

Rename the existing function, because the old name fits better the new

Layers did not have a fini sequence before, which means the compositor
layer list might have stale pointers temporarily when shutting down. A
bigger problem might be having views linger after the destruction of the
layer.
These problems were not observed yet, but if they exist, this patch
should help to find them and then fix them.
The check in weston_compositor_shutdown() is not an assert yet, because
it will trigger until all components call weston_layer_fini() correctly.
Some components do not even have a tear-down function to call it from at
all, like fullscreen-shell.
The same with the check in weston_layer_fini().

$FDO_CI_CONCURRENT is provided by in the CI environment by the fd.o
GitLab runners to tell us how many parallel processes would be 'good' to
use.
Use this to override the default Ninja invocation which uses as many
CPUs as available, and instead tell it to use as many parallel processes
as the runner thinks we should during the build process.
Tests are invoked using `meson test` inside a virtme/QEmu VM; whilst
Meson's test backend will use as many processors as availble, virtme
will by default create a single-CPU VM. So if we create a VM with as
many CPUs as we should have parallel processes, we can let it use all of
them. This also requires quadrupling the requested RAM so ASan doesn't
force us straight into OOM.

This patch creates a per-output paint node list in the same z-order as
the global view_list in weston_compositor.
The next step is to switch output repaints and backends to use the
z-order list instead of view_list.
Having a per-output paint node list for repaints allows including only
those paint nodes that actually contribute to the output image, so that
completely occluded and out-of-screen views can be ignored in libweston
core already.

This new object is created for every surface-view-output triplet. As
there is always exactly one surface for a view and it does not change
during a view's lifetime, this is really for a view-output pair or a
surface-output pair.
The object is created on-demand as a part of preparing for an output
repaint, so it applies only to surfaces that are going through repaint.
A prerequisite for that is that the surface is mapped, which means it
has a mapped view.
When any one of surface or view gets destroyed or output gets disabled,
all related paint nodes are destroyed.
In future, paint node will be useful for caching surface-output or
view-output pair dependent data:
- damage regions for overlapping outputs
- color transformations
- backend-specific bookkeeping (e.g. DRM KMS plane assigments)
- per-output repaint lists
- surface geometry transformed into output space

PS. The call in weston_view_destroy() to
weston_compositor_build_view_list() might be so that if the view has
sub-surfaces, rebuilding the view list removes those those too and
automagically deletes their views.

While this is harmless because gbm_bo_create_with_modifiers will just
fail, it's easy to misunderstand that gbm_bo_create_with_modifiers
accepts MOD_INVALID. Let's just keep modifiers_count to zero instead
and stop even trying to call that function with invalid input.
Stop using modifiers_count to decide whether the compositor supports a
format. Instead use a separate format_supported flag.

This change fixes the "touch-up" operation to clear "data_source"
by setting "seat" to NULL. This operation is done in the mouse button
release operation, but seems to have been forgotten in the "touch up"
case.
Forgetting this operation causes weston to send a "premature finish
request" error to the client which causes the client to exit.
This issue can be reproduced with the "weston-dnd" program by performing
a drag-and-drop operation with a touch input device. Once the drag
is released, the weston-dnd program will exit with an error.

Use address sanitizer to catch use-after-free and other errors when
running the test suite.
Leak detection is disabled, because currently there are too many leaks,
making almost all tests fail otherwise.
The atexit=1 is for verifying that ASan was actually used.
The default 128 MB of RAM in the qemu machine leads to oom-killer
killing most tests, so bump the memory size to 1 GB.

Fix UAF by resetting wl_resource user data, and ensuring it is valid
before used.
Setting seat->input_method to NULL may not be necessary since it is
being called from seat destroy listener, but added just in case.

Weston internals and Wayland clients assume that output presentation
clock cannot go backwards. Therefore require unconditionally that KMS
uses the monotonic clock.
The kernel unconditionally supports DRM_CAP_TIMESTAMP_MONOTONIC. See:

drm: vblank: remove drm_timestamp_monotonic parameter
That one removed the final possibility of DRM_CAP_TIMESTAMP_MONOTONIC
being false, by removing the module option. But even before that, all
drivers have been supporting monotonic, since

drm: add support for monotonic vblank timestamps
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
This drops the software presentation clocks that could jump backwards.
See the previous commit "libweston: assert frame times never go
backwards" for the rationale.

Adding this check was prompted by
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/609
There is no reason to allow frame times jump backwards, and apparently
we already have code that makes that assumption.
DRM KMS uses CLOCK_MONOTONIC as the vblank and page flip timestamps,
which by definition cannot go backwards. Other backends call
weston_compositor_set_presentation_clock_software().
Frame times are also reported directly to Wayland clients via
presentation-time extension, and clients too will not expect that the
timestamp could go backwards.
So make sure time can never go backwards.

As observed in #420 (Running Weston under Weston's kiosk shell with
multiple outputs causes the scrollback to go nuts), not
being able to cope with (a correct) resize of the parent surface would
cause the client weston instance to spin forever. If dispatching
failed, just exit.
Fixes#420

As an in-flight resize call might cause a call to
wayland_output_destroy_shm_buffers() to go over a list of free_buffers
list. Just initialize the lists before attempting to create the parent
surface to avoid it.

fb->format is *pixel_format_info, whereas fb->format->format is the
actual DRM/wl_shm format code we want to see here. Fix the drm_debug()
call accordingly.

In "backend-drm: simplify compile time array copy", ARRAY_COPY was
introduced to be used by the DRM-backend.
In this patch we expand its usage to other code where hardcoded arrays
are being copied.

In commit "backend-drm: simplify compile time array copy", the macro
ARRAY_COPY was introduced.
The macro STRING was accidentally introduced in the same commit, and as
it is completely unnecessary, remove it.
Also, memcpy was copying from src to dst, and it should do the opposite.
So fix it.

In drm_fb_get_from_dmabuf() we have some compile time array copies, and
multiple static_assert() calls are needed (for safety). This makes the
code unpleasant to read.
Add ARRAY_COPY macro, to simplify the code.

EGL implementations have no way to tell that implicit modifiers are not
supported. So Weston must consider that implicit modifiers are
supported. Always add DRM_FORMAT_MOD_INVALID to formats that we query
from EGL.
The implication is that clients using dmabuf extension may pick
DRM_FORMAT_MOD_INVALID to allocate their buffers, and so these buffers
will not be directly imported to KMS and placed in planes. See commit
"backend-drm: do not import dmabuf buffers with no modifiers to KMS" for
more details.
But we should not avoid advertising DRM_FORMAT_MOD_INVALID in the dmabuf
protocol just because we hope that the client don't choose it, it's not
our choice.

In commit "libweston: add struct weston_drm_format" struct
weston_drm_format and its helper functions were added to libweston.
The functions query_dmabuf_formats and query_dmabuf_modifiers are very
specific to GL-renderer and its internals. So instead of exposing them
in libweston, query and store DRM formats and modifiers internally in
GL-renderer. Also, add a vfunction to struct weston_renderer in order
to retrieve the formats.
