The aspect ratio definitions for 64:27 and 256:135 have been added with
libdrm 2.4.95. However, Weston currently depends on libdrm 2.4.89 or
higher. Define the definitions in Weston to support libdrm older than
2.4.95.

When the aspect-ratio-aware mode support was added to Weston, it was
done before the libdrm support was finalised and merged. Between it
being added to Weston and being merged, it changed to no longer provide
the offset for the bitmask.
Instead of using the mask and a compatible enum, if we update our
libdrm dependency, we can use the flag definitions directly from libdrm.
In 94e4068ba1, the libdrm dependency was bumped to 2.4.83, which
enabled us to remove a bunch of error-prone ifdefs by making atomic and
modifier support mandatory.
We determined in the discussion of !311 that it was safe to push the
dependency as high as 2.4.91, as that was what was available in major
distributions.
Bumping to 2.4.86 allows us to safely remove the ifdef and go with
upstream flags, as that was added in mesa/drm@0d889201d1.

In order to better optimize view assignment to HW planes, we construct
an intermediary zpos candidate list which is used aggregate all suitable
planes for handling scan-out capable client buffers.
We go over it twice: once to construct it and once to pick-and-choose a
suitable plane based its highest zpos position.
In order to maintain the view order correctly we track current zpos
value being applied to the plane state and use it when trying to place
a view into a plane.
Pass the computed zpos value to be applied to the plane state.

Functional no change, as nobody makes use of it. Only apply the zpos
value if the zpos property is mutable (that is, zpos_max and zpos_min
are not the same).

Due to an error in driving GitLab, this commit erroneously contained the
entirety of !267 (zpos support in the KMS backend) squashed into one
single commit, pushed into master.
In order to keep the history clean, this is being reverted; a rebased
version of !267 with the clear individual commits which were already
present will be applied in its place.
This reverts commit 95e3b0deae.
Make GBM optional in case GL renderer is disabled. This allows to

Move DRM virtual support into a separate file. Use the remoting
compile time option to disable DRM virtual support since this is the
only user of DRM virtual support currently. This will make it easier
to build the DRM backend without GBM support.

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.

drm_assign_planes() is called to separate views out and decide what will
be taken out for plane composition and what will be left for the
renderer to compose.
It calls drm_output_propose_state() in order to find a good
configuration, which itself has a number of helpers that it calls. Break
these out into a separate file.

Create a new file which handles most of the actual KMS API use. This
covers the property handling (in which we map between KMS properties and
our internal representations), as well as actually applying state
through atomic modesetting or the legacy SetCrtc/PageFlip/DPMS APIs.
