89f77176b6 backend-drm: Rename mm_has_underlay to mm_underlay_only
Now that secondary planes can be both underlay and overlay, this flag's
meaning also changed. Update it for correctness.

ca894ab44f backend-drm: Use plane's zpos_min to check for underlay ability
Previously, whether a KMS plane is underlay-able is determined by
whether it's zpos_max is < the primary plane's zpos_min. In other words,
a plane will only be considered underlay-able if its entire valid zpos
range is under the primary plane's lowest zpos.

This is too restrictive - it's possible for planes to have a valid zpos
range that spans below and above the primary's zpos range.

Therefore, allow planes to be used as underlays if their zpos_min is <
the primary plane's zpos_min.

In addition, force rendering on a view if it contains alpha, and is
occluded by a rendered view. If such a view is overlaid, it would render
with incorrect zorder. If it's underlaid, it would render with incorrect
alpha-blending due to hole-punching. Therefore, it must be rendered.

Force rendering prevents the view from going into
`drm_output_find_plane_for_view()`, which serves as an optimization, but
is also observed to prevent dmabuf feedback (derived from
`try_view_on_plane_failure_reasons`) from ping-ponging between two
values, causing some apps (like weston-simple-egl) to constantly
reallocate its buffers.

Because a plane can now - if supported - be used as an underlay, an
overlay, or both, add a `enum drm_plane_subtype` to differentiate
between them. Then, print it's subtype and underlay/overlay assignment
once a decision is made.

v2:
* Squash w/ patch to force rendering on alpha view occluded by rendered
  view
* Bring back plane subtype enum to be more expressive about plane
  capabilities
* Correct need_hole != false when a view's assignment changes from
  underlay to overlay

b2b8dd6215 libweston: fix crash when a client binds to a destroyed output
When the head is already destroyed, its global resource still can be
accessible by the client, which leads to a UAF crash.

This sets the head's global resource's user data to null before the
head is destroyed, and when the `bind` request is being handled but the
object's user data is null, do what we do when the the head's output is
null.

3866ecc5d3 libweston: fix crash when a client queries a destroyed output
A client can call get_xdg_output() at any time. If the output was destroyed,
then all output resources are orphaned. This includes clearing the user data of
the resource.
This can happen, for example, when a monitor or HDMI switch quickly toggles the
HDMI hotplug pin.

So check if a head is associated with the resource. If not, just create the
resource and then return immediately.

bf7b2311e7 gl-renderer: Take direct-display into consideration
The buffer_init function added with commit 83b37c0ac4, "renderers: pull

Previously, gl_renderer_attach_dmabuf, wasn't being called when dmabuf's
direct-display  was turned on, but with commit 83b37c0ac4 this has been changed.

So with commit 83b37c0ac4, linux_dmabuf_buffer_get_user_data will never
return a valid gb (gl buffer state), causing a crash using
direct-display extension. This adds an explicit check to return early
when this happens.

4f2cc67fde compositor: Prevent startup crash when hdcp mode is set on display
We can startup with the display already in type1 content protection mode.
When this happens, we call weston_output_dirty_paint_nodes() on a display
that hasn't yet been enabled. The paint node list isn't initialized yet,
so we crash.

We don't actually need to touch the paint nodes here anyway, as
weston_output_damage() ensures a repaint if the ourput is enabled, and
weston_output_dirty_paint_nodes() just forces calculation of things
unrelated to protection, and we'll override most of that in
maybe_replace_paint_node() if necessary when we get there.

Just drop the weston_output_dirty_paint_nodes() call to stop the
crash.

89f3a8a71e Add support for FreeRDP 3.x
With this, Weston can build against either FreeRDP 3.x or 2.x depending
on what has been detected by meson (3.x takes priority).

The main source of changes is the settings are now opaque and require the
use of accessors. That was pretty mechanical and seems to work on 2.x as
well.

There are a few changes around constants getting a WINPR_ prefix, the UTF
conversion functions we used are obsolete, so use the proper "new" ones,
and other fairly minor things.

The key & cert management changed rather completely, libfreerdp won't load
files for us, we have to use the helpers to do so, and I *think* the RDP RSA
key and SSL key use the same setting location. Seems to work with SSL at
least.

There was also a minor glitch with keyboard input, KBD_FLAGS_DOWN is basically
never set. It appears to be an upstream FreeRDP change in 3.x, it was being
set incorrectly (always on any key down) while it should only be set on
repeats. However the fastpath input code has no way to set it from what I
can tell, so it's just loss. We instead ignore it.

Note that the screen size is odd (and different between freerdp client and
remmina), it also won't adjust dynamically when the window is resized. I
don't think this relates to my port though, I observe the same behaviour
with the packaged FreeRDP 2 based Weston, but I can try to look into it
later

d553333da8 frontend: Share a native output using 'mirror-of' keyword
This would allow to screen-share a particular output like the
following:

[output]
name=vnc
same-as=DP-5

[output]
name=rdp-0
same-as=DP-4

[output]
name=pipewire
same-as=eDP-1

Both 'vnc', 'pipewire' 'rdp-0' remote outputs would then be a
screen-share 'DP-5', respectively, 'e-DP1', or the 'DP-4' DRM output.

Currently, this is intended only for VNC, RDP and PipeWire remote outputs.

This patch exports weston_output_set_position(), and uses that for
overlapping a remote output with a native DRM one, rather than using
weston_output_move() as that has a side-effect when reflowing outputs
from shells.

Further more creating this remote output is driven entirely by compositor
signal events such that enabling an DRM native output would enable the
remote output, while disabling the native would have the same outcome
for the remote one.

003e529d46 compositor: Unmap views moved to layers outside of the scene graph
commit 5fe02dc68e partially resolved the issue in #937 by bringing back
the old band-aid solution for layer moves. However, since the events of
commit bf228370ff and following commits we have a problem with
subsurfaces leaving garbage behind when minimized - see #366 which was
probably fixed for a while then became broken again.

When we minimize a view that has subsurfaces, by moving it to a layer
outside of the scene graph, we need to be sure to handle the subsurface
views - which follow their parent's layer instead of having
weston_view_move_to_layer() explicitly called.

Do this by assuming layers with an empty link are not part of the scene
graph and unmapping views when they're moved to these layers. This will
recursively unmap the subsurface views.

We can now remove the band-aid paint node destroy, as the unmap process
will destroy paint nodes as appropriate.

a7e8bd4bea subsurface: don't forget to repaint after the first sub-surface commit
For the following sequence, weston will not trigger a repaint:

1. create the main surface
2. create another surface and attach it as a sub-surface to the main surface
3. set the sub-surface to desync
4. attach a buffer to the main surface and commit it
5. attach a buffer to the sub-surface and commit it

Step 5 should cause the sub-surface to become mapped. However, Weston fails to
schedule a repaint in that case, so the sub-surface will not appear until
something else causes a repaint on that output, e.g. the main window.

And sub-surfaces are special when it comes to mapping because
weston_surface_is_mapped() will not return true until the parent surface is
mapped as well. So right now, weston_surface_map() may be called multiple times
and it will send the map_signal each time.

So to fix all this and make it clearer:

1. define a separate weston_surface_start_mapping() function to make it clearer
   that the (sub-)surface may not be fully mapped at the end
2. check surface->is_mapped explicitly to ensure that the sub-surface is only
   mapped once.
3. call weston_view_update_transform() for all views of the sub-surface when the
   parent surface is already mapped to ensure that a repaint for all relevant
   outputs is triggered.

The new test checks this by waiting for a frame event for the first subsurface
commit. Without these changes, the test will block until it is killed by the
timeout.
