518d72a37b compositor: add color_characteristics weston.ini option
This adds an option to program basic display color characteristics from
weston.ini. In the future there will be a way to set this information
from EDID, but because EDID is unreliable that will probably not be the
default. An ICC profile will likely override most or all of this. The
main reason to add this option is to be able to characterise HDR
monitors.

An 'output' section can have a key 'color_characteristics' (string)
set to a name. The name refers to any 'color_characteristics' section
with 'name' set to the same string.

The 'name' key of a 'color_characteristics' section cannot contain a
colon ':'. Names with colon in 'output' section key
'color_characteristics' value are reserved for future use, e.g. to
indicate that the metadata is to be taken from EDID instead of a
weston.ini section.

In some cases it may be useful to override this to increase the rate

2f9319cef6 rdp: Allow specifying a listener fd on the command line
We already have a way for a single RDP client connection to be
passed from a parent process to a child using a combination
of environment variable (RDP_FD) and env var (--env-socket)

This patch allows a bound socket fd (as opposed to a client
connection) to be established in a parent process and provided
to the rdp backend. WSLg uses this to set up an AF_VSOCK
socket for communication between a Windows RDP client and a
weston compositor running under a hypervisor.

There are currently compatibility issues between FreeRDP's implementation

Perhaps this will be fixed in the future and this option can go away,

bb1d19dc5e compositor: Launch clients in their own session
When we launch clients they currently stay in the same session as
weston, and share its controlling terminal. This means hitting ctrl-c
in weston's controlling terminal will send SIGINT to the clients as
well. It also means SIGHUP will be propagated to our launched clients
if weston's controlling terminal is closed.

While generally not harmful, this behaviour is not beneficial, and
is present by default and not by design.

Problems arise when launching weston in a debugger, as a ctrl-c sent to
the debugger will be propagated not only to the debugger, but all the child
processes sharing weston's session. This results in weston-desktop-shell
being killed by the ctrl-c that was intended to stop weston for debugging.

If weston-desktop-shell is killed within 30 second of startup, it will
result weston performing a clean shutdown. This clean shutdown can
make debugging a little too surprising.

Ostensibly, clients launched via weston_client_launch will be wayland
clients that terminate cleanly on their own if weston is killed, so
there should be no need for them to remain in weston's session to
catch ctrl-c from its controlling terminal. Nor should they need a
controlling terminal for their general operation.

Use setsid() to move them to their own session, devoid of controlling
terminal, to make using a debugger a little less confusing in some
cases.

f32bcfef42 compositor: Use sigaction to trap SIGINT
signalfd interacts badly with gdb's signal trapping - when hitting
ctrl-c in a debugger attached to weston, weston will receive the
signal. This results in weston exiting cleanly when the intent
was to use gdb to interfere with its operation.

Trapping SIGINT was introduced in commit 50dc6989 which ensured we
would call wl_display_terminate() on SIGINT or SIGTERM to clean
up our socket.

Killing weston with SIGINT is quite common for several developers,
so it's important to preserve this clean shutdown behaviour, so
we can't naively stop trapping SIGINT entirely.

Instead, use the sigaction() function to trap SIGINT, and have
the SIGINT handler send weston SIGUSR2 (SIGUSR1 is already
used by xwayland). SIGUSR2 can be trapped in the proper wayland
way via wl_event_loop_add_signal(). This way we can properly
break our event loop and clean up on SIGINT, but we can also
have gdb intercept SIGINT.

There are other ways around this, but I'm hoping this one allows
people to continue using ctrl-c to stop weston, and doesn't
require additional project specific gdb knowledge.

2f71b3c3de compositor: Stop trapping SIGQUIT
We've been trapping SIGQUIT for a "clean shutdown" since commit 3cad436a

However, sources such as:
http://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html
indicate we probably shouldn't be trapping it at all, as the intent of
SIGQUIT is to leave a core file and debug artifacts from the run.

We should perform the minimal amount of clean up to ensure the system isn't
left in an unusable state - but these days that's performed by other
software such as logind.

We can safely stop trapping SIGQUIT entirely.

b3ba1becba libweston: remove fbdev backend
Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.

Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.

I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.

Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

a882794027 compositor: add icc_profile weston.ini option for outputs
This adds "icc_profile" key support in [output] sections for backends
headless, x11, wayland, and drm, and also for remoted and pipewire
outputs FWIW. On the other hand, RDP-backend does not use output
sections from weston.ini, and fbdev-backend does not deserve anything
new (it wouldn't support color management anyway due to no GL-renderer).

This allows one to configure an ICC v2 or v4 file to be used as an
output profile. However, color-lcms does not actually use output
profiles yet, so trying this will fail until support is implemented.

The parent_winsys_profile argument is reserved for using the color
profile from a parent window system where applicable, if nothing else is
set in weston.ini. None of the nested backends provide an output color
profile yet. It is more of a reminder of a missing feature than a
serious implementation.

Note: cms-static Weston plugin uses the exact same weston.ini key for
loading VCGT from ICC profiles. If "color-management" option is set to
false, this new use of "icc_profile" is disabled and the old behavior
with cms-static is kept.

81ef6d0ab3 compositor: add weston.ini option use-renderer-shadow
This adds an output section option use-renderer-shadow in weston.ini.
This option is only recognized with headless and DRM backends, because
it requires GL-renderer and does not support resizing outputs.

The option is called use-renderer-shadow because this is what it does
right now. In the future the same setting will be used to turn on more
complex image processing when operational pieces required for color
management land. Once color management is implemented, this option is
expected to be removed. This option allows developer testing of features
to be used to implement color management.

This is a rewrite of "weston.ini: introduce use-shadow-fbo in output
config" by Harish Krupo. The main.c code is structured differently, the
weston.ini option is renamed, and the man page paragraph is moved to
weston.ini.man with different content.

b5265af620 libweston: add color ops cap and bool renderer shadow buffer
This adds the libweston capability bit for "color operations" which
refers to a renderer's support for operations needed for color
management. GL-renderer will grow the support while Pixman-renderer will
not, which is why the cap is needed.

To make an example use of the cap, this also adds new API:
weston_output_set_renderer_shadow_buffer(). This is a temporary API to
enable future experimental features. The first such feature will be the
renderer internal shadow buffer, the boolean variable for it taken from
Harish Krupo's "weston.ini: introduce use-shadow-fbo in output config".

Obviously this patch does not implement the renderer shadow buffer. No
renderer sets WESTON_CAP_COLOR_OPS yet so trying to enable it will fail.

The documentation here is deliberately vague, because the bits needed
for color management will come in trickling for a long time until we can
call it color management in any sense. Until then, the temporary API
shall remain, perhaps poorly named.

32a5acde5b tests: add mechanism to change Weston's behavior when running certain tests
There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.

For instance, in the DRM backend we plan to add a writeback

reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

ae69381b6e compositor: avoid setting WAYLAND_DISPLAY=wayland-0
This commit alters the way that Weston picks a Wayland display socket
name. Instead of using wl_display_add_socket_auto to look for the first
available name in wayland-0, wayland-1, .... to wayland-32, the code now
checks names wayland-1, wayland-2, .... up to wayland-32.

This change is a workaround for a suboptimal behavior of
libwayland-client. If a client program calls wl_display_connect(NULL) and
the WAYLAND_DISPLAY environment variable is not set, then the program will
by default try to connect to 'wayland-0'. This is a problem when a
computer has a running Wayland compositor but is being accessed in some
other fashion, such as through an X session on a different virtual
terminal, over ssh, etc. Client programs launched through those means may
attempt to connect to an unrelated compositor. Changing libwayland
behavior to remove the default would also work, but a) libraries have
stronger backward compatibility expectations b) that would likely break
more people's setups than just changing Weston would.

After !383, this will result in configurations using the old definition
failing and exiting, rather than continuing on the wrong way around.

31af69d868 compositor: Fix default transforms when output section declared
Regardless of the default transform passed in, weston_parse_transform
would always return 'normal' if there was an output section. This is
because, if a section was declared for that output, it would ask
weston_config for the transform, with the default being 'normal'.

Fix it so we return the passed-in default transform when we have a
matching output section without a transform key. If the transform is
declared but invalid, we can remove the line resetting to the default
transform, because we've already set the default transform up top.

8060d826b7 Redefine output rotations
It was discovered in issue #99 that the implementations of the 90 and 270
degree rotations were actually the inverse of what the Wayland specification
spelled out. This patch fixes the libweston implementation to follow the
specification.

As a result, the behaviour of the the weston.ini transform key also changes. To
force all users to re-think their configuration, the transform key values are
also changed. Since Weston and libweston change their behaviour, the handling
of clients' buffer transform changes too.

All the functions had their 90/270 cases simply swapped, probably due to
confusion of whether WL_OUTPUT_TRANSFORM_* refers to rotating the monitor or
the content.

Hint: a key to understanding weston_matrix_rotate_xy(m, c, s) is that the
rotation matrix is formed as

  c -s
  s  c

that is, it's column-major. This fooled me at first.

Fixing window.c fixes weston-terminal and weston-transformed.

In simple-damage, window_get_transformed_ball() is fixed to follow the proper
transform definitions, but the fix to the viewport path in redraw() is purely
mechanical.  The viewport path looks broken to me in the presence of any
transform, but it is not this patch's job to fix it.

Screen-share fix just repeats the general code fix pattern, I did not even try
to understand that bit.

9aaaf96a6a compositor: destroy log context only after the destruction of subscribers
Before commit "weston-log: destroy subscriptions with
destruction of subscribers", we had to destroy subscribers
before the log context. Currently there's no required order,
both are valid.

But since we've created log context before the subscribers,
we can destroy it after them. This is a style change and
also a prove that now this order is valid as well.

1ded661aac weston-log: merge functions that destroy different types of subscribers
Log subscriber API is not type-safe. File and flight recorder
subscribers are created with functions that return
weston_log_subscriber objects. But there's a problem: to destroy
these objects you have to call the right function for each type
of subscriber, and a user calling the wrong destroy function
wouldn't get a warning.

Merge functions that destroy different types of subscribers, making
the log subscriber API type-safe.

ca640d5120 libweston: fold weston_compositor_tear_down() into weston_compositor_destroy()
The only reason why we have both weston_compositor_tear_down() and
weston_compositor_destroy() is that the only we had to destroy
the log context was keeping weston_compositor alive and calling
weston_log_ctx_compositor_destroy().

After commit "weston-log: replace weston_log_ctx_compositor_destroy()
by weston_log_ctx_destroy()", it's not necessary to keep a zombie
weston_compositor just to be able to call
weston_log_ctx_compositor_destroy().

Fold weston_compositor_tear_down() into weston_compositor_destroy(),
as this split is useless now.

4ec38d18b3 weston-log: replace weston_log_ctx_compositor_destroy() by weston_log_ctx_destroy()
The function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a
weston_log_context unlinked from a weston_compositor and currently there
is no way to destroy it.

Add function weston_log_ctx_destroy(), what makes the destruction of
weston_log_context independent of weston_compositor.

With this change, one could destroy a weston_compositor and keep the
related weston_log_context (since now weston_log_context can be destroyed
without the need of a weston_compositor). But if weston_compositor gets
destroyed it's also necessary to destroy weston_log_context::global,
as the debug protocol depends on the compositor. So a listener has been
added to the destroy signal of weston_compositor.
