With it add also a function which can be used in an assert()-like
situation to display the contents of the ring buffer. Within gdb
this call also be called if the program is loaded/still loaded into
memory.
The global variable will be used in a later patch to be accessed from a
python gdb script.

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

Since version 7 clients must use MAP_PRIVATE to map the keymap fd so we
can use memfd_create in os_ro_anonymous_file_get_ref using
RO_ANONYMOUS_FILE_MAPMODE_PRIVATE, for older version we use
RO_ANONYMOUS_FILE_MAPMODE_SHARED to be compatibile with MAP_SHARED.

Use the surfaceless platform in the headless backend to initialize the
GL-renderer and create pbuffer outputs. This allows headless backend to use
GL-renderer, even hardware accelerated.
This paves way for exercising GL-renderer in CI and using the Weston test suite
to test hardware GL ES implementations.

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.

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.

Depending on system loading, weston-launcher could drop the drm
master access before the compositor and all the clients receive
the notification. In this case, some commit could be sent to the
drm driver too late and get refused with error EACCES.
This error condition is not properly managed and causes weston to
hang.
Change the return type of start_repaint_loop() and repaint_flush()
from void to int, and return 0 on success or -1 if the repaint has
to be cancelled.
In the callers of start_repaint_loop() and repaint_flush() handle
the return value and cancel the repaint when needed.
In backend-drm detect the error EACCES and return -1.
Note: to keep the code cleaner, this change inverts the execution
order between weston_output_schedule_repaint_reset() and
repaint_cancel().
No need to wait for suspend or for any notification; in case the
weston reschedules a repaint, it will get EACCES again.
At resume, damage-all guarantees a complete repaint.
This fix is for atomic modeset only.
Legacy modeset suffers from similar problems, but it is not fixed
by this change. Since drm_pending_state_apply() never returns
error for legacy modeset, this change has no impact on legacy
modeset.

The protection requested for a given surface, must reach through the
weston_surface::pending_state, in the commit-cycle for the
weston_surface, so that it gets updated in the next commit.
As some protection is requested for a given weston_surface, it means
protection must be set for each of the outputs which show the surface.
While setting the protection of a weston_output, care must be taken
so as to avoid, degrading the protection of another surfaces, enjoying
the protection. For this purpose, all the weston_surfaces that are
shown on a weston_output are checked for their desired protection.
The highest of all such desired protections must be set for the
weston_output to avoid degrading of existing protected surfaces.
A surface requesting protection for a lower content-type can still be
provided protection for a higher type but the converse cannot be
allowed.
This patch adds support to set content-protection for a suface, which
inturn sets the content-protection for each of the outputs on which
it is shown, provided, none of the existing surface's protection
request is downgraded.

The actual protection status for a given weston_head depends upon the
corresponding drm_head's connector HDCP properties. On the other hand,
the actual protection for a weston_output is the minimum of the
protection status of its attached heads.
As a head's protection changes, the current protection of the output
to which the head is attached is recomputed.
This patch adds the support to keep track of the current
content-protection for heads and the outputs.
