If we don't have the surfaceless_context extension, we create a pbuffer as a
dummy surface to work with. If we also don't have configless_context, then it
is possible the config used for creating the context does not support pbuffers.
Therefore, if both conditions apply, we need to pick a config that supports
both window and pbuffer surfaces.
This makes the "base" config compatible, but it does not yet guarantee that we
actually pick it again when creating the pbuffer surface. Fixing that is
another patch.

Now that all backends pass in a list of acceptable DRM formats, that is used to
determine if the EGLConfig has an alpha channel or not. Therefore the
opaque_attribs and alpha_attribs are now useless, and we can remove the whole
config_attribs argument from the API.
gl_renderer_get_egl_config() uses an internal attrib list that matches at least
the union of the opaque_attribs and alpha_attribs matches.
Overall, behaviour should remain unchanged.
The new attribute array becomes variable in the future, so it is left
non-const.

Define a specific DRM format for the GL-renderer to render in. It goes through
fuzzy matching in egl-glue.c which ensures we get exactly the number of bits
for each channel, but does not require an exact format match.
This ensures we get the bit depth we expect instead of the first arbitrary
EGLConfig.
This should not change the current behaviour, because Mesa EGL takes care to
order the configs as apps expect.

Implement fuzzy EGLConfig pixel format matching, where we ensure that R, G, B
and A channels have the expected number of bits exactly. This is used on EGL
platforms where the EGLConfig native visual ID is not a DRM format code. On EGL
GBM platform, the old exact matching of native visual ID is kept.
As only the DRM backend uses a DRM format list for picking a config, this patch
should not change any behaviour.

Using arrays of pixel_format_info instead of just DRM format codes is useful
for fuzzy matching of formats with EGLConfigs in the future. The immediate
benefit is that we can easily print format names in log messages.
We should never deal with formats we don't have in our database, so discarding
unknown formats should be ok. Using unknown formats would become hard later,
too.

These fields are necessary when looking for an EGLConfig matching a pixel
format, but the configs do not expose a native visual id. Such happens on the
EGL surfaceless platform where one does not actually care about the exact pixel
format, one just cares it has the right number of bits for each channel and the
right component type.
FP16 formats are coming, so this paves way for them too, allowing them to be
described.
The FIXED/FLOAT terminology comes from EGL_EXT_pixel_format_float.

In an attempt to pull more of EGLConfig choosing into one place, refactor code
into the new gl_renderer_get_egl_config(). The purpose of this function is to
find an EGL config that not only satisfies the requested attributes and the
pixel formats if given but also makes sure the config is generally compatible
with the single GL context we have.
All this was already checked in gl_renderer_create_window_surface(), but
gl_renderer_create_pbuffer_surface() is still missing it. This patch is
preparation for fixing the pbuffer path.

Some drivers support EGL_EXT_image_dma_buf_import_modifiers for format
enumeration, but don't have any modifiers. In this case, on platforms where
malloc(0) returns non-NULL, we would leak that allocation to the caller.
Handle this by noticing when the number of supported modifiers is 0 and

In case of enforced protection mode, the renderer takes care of

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.

Fixes: 4b6e73d617 ("libweston: Add support to set content-protection for a weston_surface")
This was caused by weston_wm_handle_xfixes_selection_notify() calling
weston_seat_set_selection() with a NULL source, apparently only
sometimes when closing an Xwayland window.
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.

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).

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.

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

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.

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.
