Add a new --backends command line option and a backends option to the
configuration file that both take a comma-separated list of backends,

The first backend is the primary backend and provides the renderer.

When multiple backends are loaded simultaneously, they all have
to register their own head change notification listener and
output configuration callback.
To avoid calling output configuration for heads created by other
backends, only iterate over heads that were created from the given
backend by comparing the weston_head::backend pointer to the one
stored in the head change notification listener.

Let backends declare the presentation clocks they can use with a
new bitfield weston_backend::supported_presentation_clocks and set
presentation clock after loading the backend in the compositor.
Make weston_compositor_set_presentation_clock() internal and replace
weston_compositor_set_presentation_clock_software() with an exported
weston_compositor_backends_loaded(), which is called by the compositor
after the backend is loaded.
In the future, this can be extended to determine the subset of clocks
supported by all backends.

On a desktop system, the expected behavior during a Weston start is that if any
monitor can be enabled, Weston starts up and enables the monitor. Outputs that
could not be enabled, stay disabled. This helps the user in debugging the failed
outputs.

If Weston fails to configure a DRM output for whatever reason, it will fail to
start. Depending on the use-case, this may or may not be the correct behavior.
Add the "require-outputs" option to allow configuring the error behavior on
missing outputs.
Add documentation of the possible options to the man page.

Currently Xwayland is cleaned up by a destroy listener. The problem with
this is that this is true for both libweston's Xwayland support as well
as the frontend's.
Add an explicit destroy step to Xwayland frontend which will cleanly
destroy the process as well as any other resources.

Every time we call wet_client_launch, we now allocate a new wet_process,
which is always cleaned up by the compositor core and not by the users.
In doing this, weston_client_launch is renamed to wet_client_launch,
since wet_ is for the frontend and weston_ is for libweston.

Instead of reusing an inline wet_process struct, allocate a new
wet_process every time we go to launch Xwayland.
Signed-off-by: Daniel Stone <daniels@collabora.com>
wet_process provides a cleanup function which can be called, but only
passes the process itself. This relies on the process struct being
inlined in something else meaningful, and means that we can't allocate
them on demand.
Add a 'data' argument which allows users to pass meaningful data to
their cleanup handler.

Hardcode the ad hoc EDID parser to always claim that only SDR is
supported. Even though libdisplay-info is not yet asked for HDR
capabilities, it shall be the only way to see them.
To be nicer to experimenters, main.c adds a note that you really need
libdisplay-info if you want to play with HDR.

Now that our process-launching internals are identical between the
(still-misnamed) weston_client_launch and the frontend's Xwayland
launcher, we can reuse the internals instead of open-coding it.
As a result, we now additionally prevent Xwayland from inheriting
Weston's signal mask, by clearing SIG_UNBLOCK on all signals. This
should have no observable effect as we do not depend on signal handling
within Xwayland, instead using the displayfd readiness mechanism since
c2f4201ed2.

weston_client_start() takes only a single path with no arguments,
forking a process to start that command line, and creating a client from

When we launch a child, we need to clear CLOEXEC on any FDs we want to

Add a separate PipeWire backend based on the PipeWire plugin. The backend
requires PipeWire 0.3.x.
The PipeWire backend can be used as a standalone-backend backend for streaming
and composing Wayland clients to PipeWire.
The backend supports the on-demand creation of heads via the
weston_pipewire_output_api_v1. It also supports per-output pixel format
configuration via a gbm-format option.
Multiple PipeWire outputs can be created by setting the num-outputs option in
the [pipewire] section.

Pass the backend instead of the compositor to the windowed output API
create_head() method and increment the API version.
That way the backend will not have to find the backend pointer from the
compositor. This is trivial now, but in the multi-backend case would
entail iterating over all backends to find the correct one.

Add the --additional-devices parameter to Weston to add secondary drm devices

We can only fail the repaint for the entire backend, but not for single

Push weston_coord into the notification functions instead of passing
