14533cdd25 libweston: make weston_renderbuffer refcounted
Add weston_renderbuffer_ref/unref() functions and use them to
eventually destroy the weston_renderbuffer. Drop the explicit
renderbuffer_destroy vfunc from the pixman renderer interface.

fc8d260ce3 libweston, backends: move GL renderer interface into weston_renderer
Move the struct gl_renderer_interface pointer from the backends into
the weston_renderer structure. The interface struct only contains
function pointers that never change, so make it const.

Load and initialize the GL renderer in libweston instead of in the
backends, using the new weston_compositor_init_renderer() function.

e96494801b compositor: Clarify if view is in a layer
As seen in some instances, subsurfaces do not have an entry in their
layer_link, as we bring them into existence rather directly in  the
view_list and not using the layer list approach.

This adds two messages to the debug scene graph to point out if the
views aren't really in any layer or if they're indirectly in the view
list using an ancestor (the main parent view actually).

Passing the backend as a parameter to the weston_backend function

Since all backends already store a pointer to the compositor instance,

7086b9eac2 libweston: Avoid using the surface's output when emitting a timeline
This is an odd corner case where the surface doesn't yet have an output
assigned -- noticed when starting up with the RDP backend and
fullscreen-shell, and we attempt to emit a timeline point for a surface
without an output assigned, causing weston to crash when that
happens.

Rather than trying to catch this in the timeline code, still emit the
flush damage timeline but instead of using the output the surface is on,
use the output that accumulates damage.

3700c78131 libweston: implement new screenshooting protocol base
This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.

See the previous commit "protocol: new screenshooter protocol" for why.

If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.

The DRM-backend no-damage optimization requires special handling here as
well. See also 7f1a113c89 .

This adds basic VNC protocol support using the Neat VNC library
(https://github.com/any1/neatvnc). Neat VNC depends on the AML main
loop library. The backend makes use of AML's integrated epoll backend
and connects AML via file descriptor with the Wayland event loop.

This implementation does not support authentication and hardcodes the
pixel format currently.

8636422309 libweston: add weston_renderer::resize_output()
Previously renderers were not told when the output (framebuffer they
need to draw) size changed. Renderers just pulled that information out
from weston_output::current_mode when they happened to need it. This
makes some things awkward, like resizing the shadow or intermediate
buffers. In fact, Pixman-renderer does not even support resizing its
shadow buffer, nor does GL-renderer. DRM-backend has to destroy and
re-create the renderer output state anyway, but rdp, x11 and wayland
backends would be natural users of resizing API.

This commit adds an API for resizing with empty implementations. Actual
implementations will be added in following patches for each renderer
while moving parts of resizing code from backends into the renderers.
No-op renderer needs no implementation.

Only wayland-backend has actual resizing code already, and that is made
to call the new API. Unfortunately, Pixman and GL renderers differ: one
does not blit them while the other does. In order to assert the
functionality of each renderer to keep the API consistent,
wayland-backend needs to lie to pixman-renderer. That's not new, it
already does so in wayland_output_get_shm_buffer() where the 'pm_image'
addresses only the interior area instead of the whole buffer.

3b3fdc52c3 backend-drm: improve atomic commit failure handling
When an atomic commit fails then the output will be stuck in
REPAINT_AWAITING_COMPLETION state. It is waiting for a vblank event that was
never scheduled.
If the error is EBUSY then it can be expected to be a transient error. So
propagate the error and schedule a new repaint in the core compositor.

This is necessary because there are some circumstances when the commit can fail
unexpectedly:
- With 'state_invalid == true' one commit will disable all planes. If another
  commit for a different output is triggered immediately afterwards, then this
  commit can temporarily fail with EBUSY because it tries to use the same
  planes.
- At least with i915, if one commit enables an output then a second commit for a
  different output immediately afterwards can temporarily fail with EBUSY. This
  is probably caused by some hardware interdependency.

The paint_node_z_order_list contains all views, not just the ones visible on the

This will be relevant with multiple backends: When an output without plane
support is rendered then the views of all other outputs are removed from
the current planes and the corresponding outputs will be repainted
unnecessarily.

So only reset the plane if the view is actually on the current output.
