Currently, the idle task for updating surface protection is scheduled
in case of change in the output mask of a surface or in case of change
in protection status of an output.
This patch adds a function for reusing the code to schedule the
idle-tasks, that can be called whenever there is a chance of a change
in the protection status of a surface.

The member disable_planes of weston_output signifies the recording
status of the output, and is incremented and decremented from various
places. This patch provides helper functions to increment and decrement
the counter. These functions can then be used to do processing, before
and after the recording has started or stopped.

Currently drm-layer supports HDCP1.4 using connector property:
Content Protection. This property if available for a platform, can be
read and set for requesting content-protection.
Also, the patch series [1] adds HDCP2.2 support in drm, and patch [2]
adds support to send udev events for change in connector properties,
made by the kernel.
This patch adds these HDCP connector properties in weston, and exposes
the content-protection support to the client for drm-backend.
It adds the enums to represent 'Content Protection' and 'Content Type'
connector properties exposed by drm layer. It adds a member
'protection' in drm_output_state, to store the desired protection
from the weston_output in the drm-backend output-repaint cycle. This
is then used to write the HDCP connector properties for the drm_heads
attached to the drm_output.
The kernel sends uevents to the user-space for any change made by it
in the "Content Protection" connector property. No event is sent in
case of change in the property made by the user-space.
It means, when there is a change of the property value from "DESIRED"
to "ENABLE" i.e. successful authentication by the kernel, a uevent
will be generated, but in case of userspace requesting for disabling
the protection by writing "UNDESIRED" into the property, no uevent
will be generated.
This patch also adds support for handling new udev events for HDCP
connector property changes. Any such change, triggers change in the
weston_head's current_protection.

62626cbfec ensures that the GL render will not render a view's content
to the screen when the surface has requested a higher content-protection
level than the output currently offers.
When the HDCP MR was split into the core content-protection support in !83
and specific DRM support for HDCP in !48 (not yet landed), this opened a
hole where the DRM backend could promote a view to a hardware plane,
even if the output offered a lower protection level than the surface
wanted to enforce.
In the DRM backend, check the desired protection level, and refuse to
promote the view to a hardware plane if the output does not offer
sufficient protection. This will lead to presentation falling back to
the renderer, which may censor the content, reduce quality, etc.

The function pixman_blt may return false in case there is no

This has been observed on Weston compiled for aarch64. In currrent

aarch64 available.
Use pixman_image_composite32 instead which is guaranteed to have a

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

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.

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.
