Although we already supported minor version 2 of the explicit sync
protocol, we couldn't advertise it previously, since it was not in any
released version of wayland-protocols. With the release of
wayland-protocols 1.18, which includes minor version 2 of this protocol,
and the recent update in weston to require 1.18, we can now safely
advertise minor version 2.

Commit 4fc5dd0099 ("compositor: add capability CAPTURE_YFLIP")
introduced a capability flag which indicates whether y-flipping is
necessary. As already indicated in that commit message, it seems
that pixman flipps the y-axis only due to historic reasons.
Drop y-flipping and use the WESTON_CAP_CAPTURE_YFLIP flag to
indicate that y-flipping is not necessary. This simplifies code
and improves screen share performance (on my test by about 3% down
to 18% CPU load on the sharing instance of Weston).

It is quite similar to the remoting plugin. It just exports the frames via
pipewire instead of the builtin GStreamer pipeline.
It implements the same virtual output API. Virtual outputs can be created
by adding 'pipewire-output' sections to weston.ini.
The generated frames can be accessed with any pipewire client. e.g. with
GStreamer:

Adds initial grouping for sphinx/breathe for the logging/debugging
framework. We add a few groups: log (public API), internal-log (private API,
not exported) and debug-protocol, specific to the weston
debug protocol.
In latest version of breathe, '\memberof' command is recognized as such.
But it conflicts with '\ingroup' command and can't be used in the same
time (leading to duplicate symbols), so we follow a simple rule: object
tagging with '\ingroup' then use '\memberof' command for the functions
that work on that object.
There's also a caveat here: we have objects that are private (opaque)
but the functions are public. For those cases we resort to using
'internal-log' for the object (class) and 'log' for the functions.

We have dedicated header for the internal parts of the logging
framework, use that for the set-up part instead of the libweston public
API header.
Further more this removes weston_vlog() from public header as well and
moves them to weston-log-internal.h file.

Logging should start as early as possible so create the log scope as
early as possible, before subscribing to it.
Open the logfile before creating the 'logger' subscriber, making sure
we're logging to the file properly.
Also migrate `weston_log_set_handler()` to avoid potential calls to
`weston_log` before installing the log handler.

Destroying the compositor after destroying the log scope will not print
out the messages in the tear down/clean-up phase of the compositor, so
add a new tear_down function which allows keeping a valid reference to
the compositor. This way we can destroy the compositor before destroying
the scope and keep the debug messages.
While at it remove the log context destroy part from the clean-up
of the compositor and make it stand on its own.

Rather than using 'begin_cb' rename it to a more suitable name.
Further more instead of using the scope use the subscription to pass as
an argument. The source scope is attached to the subscription when
creating it so we can access it that way.
This also adds a _complete and a _printf method for the subscription
such that the callbacks can use to write data to only _that_
subscription and to close/complete it, otherwise writing to a scope
results in writing to all subscriptions for that scope which is not
correct.
In the same time, the scope counter-parts of _write and _complete will
now use the subscription function as well.

This avoids duplicated bits, by calling the scopes's callback (if any)
and adding the subscription to the scope's subscription list. Further
more, the scope's name when creating the subscription is not needed so
removed that as well.
In mirror, also inline removing of subscription for scope's subscription
list. Fix a potential corner case when the user can request a
subscription to an invalid scope in stream_destroy().

As described in e10c9f89826bb: "weston-debug: Introduce...", the
subscriber object need further functionality to make use of it.
Current form of the weston-debug protocol would not need this, as it
creates underneath a new subscriber each time a client connects and
subscriptions are created/destroyed automatically with the help of
wayland protocol. For other types of streams, we require to manually
create a subscriber and to subscribe to log scopes.
This patch introduces the ability to create subscriptions, and
implicitly to subscribe to (previously created) scopes.
In the event the scope(s) are not created we temporary store the
subscription as a pending one: a subscription for which a scope doesn't
exist at the time of the subscription. When the scope for which the
subscription has been created we take care to create the subscription as
well.
While at it the documentation bits are modified accommodate the subscribe
method and its further functionality.
Lastly, it removes an unlikely case when a scope is not created so we
avoid any kind of dandling (pending) subscription in case there is
subscription to it. We can only do something about in the destroy part
of the scope.

Adds a minimalistic API for managing the subscription object. The
subscribe functionality will be brought in once we re-organize a bit
weston-debug-stream and split it properly. It extends the logging
context with a linked list of potential subscription and adds a linked
list of subscriptions in the log scope.
This patch represents the start of a logging framework for weston. It's
being built around weston-debug, with the intent to superseded it, and
make weston-debug a client of the framework. Further more the logging
framework should replace current logging handler and allow other types
of streams to be used.
Currently present in libweston under weston-debug we have log scopes, debug
streams and a logging context.
With this patch, two (internal) objects are being added: the concept of
a subscriber and the concept of subscription. The subscription object
is a ephemeral object, implicitly managed which is created each time one
would want to a subscribe to a scope. The scope will maintain a list of
subscriptions and will continue to be explicitly managed.
The streams will use the subscriber object as a base class to extend
upon. By doing so it allows to customize the stream with specific
functions that manipulate the underlaying storage. The subscriber object
will require a subscribe function and specific stream functions and like
the scope, will be explicitly managed.
