GStreamer can accept up to four planes for a buffer; gcc isn't _quite_

Simple client to test the dma-buf feedback implementation. This does not
replace the need to implement a dma-buf feedback test that can be run in
the CI. But as we still don't know exactly how to do this, this client
can be helpful to run tests manually.

In commit "libweston: add initial dma-buf feedback implementation" we've
added initial support to dma-buf feedback, but it was not using the
feedback from DRM-backend to add useful per-surface feedback.
In this patch we add this. The scanout tranche of the per-surface
feedback is based on the union of formats/modifiers of the primary and
overlay planes available. These are intersected with the
formats/modifiers supported by the renderer device.
Also, it's important to mention that the scene can change a lot and we
can't predict much. So this patch also adds hysteresis to the dma-buf
feedback. We wait a few seconds to be sure that we reached stability
before adding or removing the scanout tranche from dma-buf feedback and
resending them. This help us to avoid spamming clients and leading to
unnecessary buffer reallocations on their end.
Here's an example of what we want to avoid:
1. We detect that a view was not placed in a plane only because its
format is not supported by the plane, so we add the scanout tranche
to the feedback and send the events.
2. A few milliseconds after, the view gets occluded. So now the view
can't be placed in a plane anymore. We need to remove the scanout
tranche and resend the feedback with formats/modifiers optimal for
the renderer device. The client will then reallocate its buffers.
3. A few milliseconds after, the view that was causing the occlusion
gets minimized. So we got back to the first situation, in which the
format of the view is not compatible with the plane. Then we need to
add a scanout tranche and resend the feedback...

This adds the initial dma-buf feedback implementation, following the
changes in the dma-buf protocol extension.
The initial dma-buf feedback implementation gives support to send
default feedback and per-surface feedback. For now the per-surface
feedback support is very basic and is still not implemented in the
DRM-backend, what basically means that KMS plane's formats/modifiers are
not being exposed to clients. In the next commits of this series we add
the DRM-backend implementation.

Constraining the buffer size of an EGLConfig to 32 means that

Starting with commit 'desktop-shell: Embed keyboard focus handle code

weston_desktop_surface to be able to invalidate the activate surface.
Upon compositor tear down the shell destroy might invalidate seats
before removal of the weston_desktop_surface making the shell_seat
itself invalid. This wasn't apparent at that time because we're not

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.

Add API to set an output's color profile. This new function can also be
called while the output is enabled. This allows changing the output
color profile even at runtime if desired.
color-noop has no way of creating weston_color_profile objects, so it
just asserts that no color profile is set.
color-lcms does not yet implement taking the output color profile into
account, so for now it just fails everything if a profile is set.
weston_surface_color_transform_fini() was previously used only prior to
freeing the struct, but now it is used also to just clear the struct,
hence it needs to reset the fields.

Roughly speaking, a color profile describes the color space of content
or an output. Under the hood, the description includes one or more ways
to map colors between the profile space and some standard profile
connecting space (PCS).
This object is not called a color space. A color space has a unique
definition, while a color profile may contain multiple different
mappings depending on render intent. Some of these mappings may be
subjective, with an artistic touch.
When a source color profile and a destination color profile are combined
under a specific render intent, they produce a color transformation.
Color transformations are already preresented by weston_color_transform.
This patch adds the basic API for color profile objects. Everything
worthwhile of these objects is implemented in the color managers:
color-noop never creates these, and in color-lcms they are basically a
container for cmsHPROFILE, the Little CMS object for color profiles.
Color profile objects will not be interpreted outside of the color
managers, unlike color transformations.
For a start, the color manager API has one function to create color
profiles: from ICC profile data. More creation functions for other
sources will be added later.
The API has errmsg return parameter for error messages. These are not
simply weston_log()'d, because CM&HDR protocol will allow clients to
trigger errors and the protocol handles that gracefully. Therefore
instead of flooding the compositor logs, the error messages will
probably need to be relayed back to clients.
Color-lcms is expected to create a cmsHPROFILE for all kinds of color
profiles, not just for those created from ICC profile data. Hence,
color-lcms will fingerprint color profiles by the MD5 hash which Little
CMS computes for us. The fingerprint is used for de-duplication: instead
of creating copies, reference existing color profiles.
This code is very much based on Sebastian Wick's earlier work on Weston
color management, but structured and named differently.

When trying to get Weston to run on a new system I was building up bit
by bit, I encountered a problem: when I started weston-terminal, it
would close a split second later. This turned out to be because
weston-terminal defaults to trying to spawn /bin/bash, which my
busybox-based system didn't have.
I can configure the terminal to use a shell I do have, of course, but I
think /bin/sh is a much friendlier default, because it's more likely to
exist (POSIX requires it), and will save people just trying to get
started with Weston from the confusing experience I had. I think it's
better overall that somebody who specifically wants /bin/bash has to
configure that (if they even have to — depending on how they're running
Weston, $SHELL might already be /bin/bash) than somebody who just wants
to see the terminal working debug why it won't launch at all.
I realise there might be a (small) backward compatibility concern here
as well, but I hope I've made the case for a friendlier default.
