76e69f2375 backends/native: Read color space and HDR metadata connector state
The HDR Static Metadata InfoFrame contents are described in CTA-861.3
and the kernel maintains a representation of that in `struct
hdr_metadata_infoframe` in `include/uapi/drm/drm_mode.h`.

33ee155630 kms-connector: Add "max bpc" property
This limits the bits-per-channel colour depth of the signal that
the connector is allowed to output.

feadaacfdd kms/connector: Add getter for preferred mode
This replaces a helper used in tests. The intention is to use it from
other tests, and seemed like a good fit to place it under the KMS
connector object itself.

43a1ba3432 tests: Add KMS device tests
As other KMS tests, depends on being DRM master and vkms being loaded.

Currently consists of a sanity check that checks for the expected set of
connectors, CRTCs, planes, etc.

47d7bc7a13 backends/kms: Implement privacy screen handling and setting
Privacy screen events on connector are handled as notification events
that won't cause any monitors reconfiguration but will emit monitors
changed on DBus, so that the new value can be fetched.

We monitor the hardware state so that we can also handle the case of
devices with hw-switchers only.

In case a software state is available it means we can also support
changing the state, and if so expose the state as unlocked.

e7ae1978f8 kms/connector: Don't use MetaConnectorType for connector type
Use uint32_t as that is what it is in the drm layer. MetaConnectorType
will be less suitable, as it will grow custom connector types that can't
be mapped.

ec7667fc31 kms/connector: Set DPMS and underscanning directly on the update
Instead of telling MetaKmsConnector fill a MetaKmsUpdate with connector
property changes, make the update itself aware of the changes, making
the impl side translate that to property changes.

f0d3201dab kms: Add MetaKmsMode abstraction
This contains a copy of a drmModeModeInfo, describing a mode. It also
has an unused pointer to the impl device it is associated with. It'll
later be used to get a blob ID for the mode.

7564c2f2e4 kms: Skip displays with 'non-desktop' property set
Detect displays marked as 'non-desktop' by the kernel and skip them when
creating the outputs. Mutter is not able to render images that are shown
properly on those devices anyway.

This avoids lighting up attached VR HMDs and showing the GDM login
screen between the eyes in a VR HMD instead of on the monitor.

75dff3e7c9 backend/native: Add and use transactional KMS API
This commit introduces, and makes use of, a transactional API used for
setting up KMS state, later to be applied, potentially atomically. From
an API point of view, so is always the case, but in the current
implementation, it still uses legacy drmMode* API to apply the state
non-atomically.

The API consists of various buliding blocks:

 * MetaKmsUpdate - a set of configuration changes, the higher level
handle for handing over configuration to the impl backend. It's used to
set mode, assign framebuffers to planes, queue page flips and set
connector properties.
 * MetaKmsPlaneAssignment - the assignment of a framebuffer to a plane.
Currently used to map a framebuffer to the primary plane of a CRTC. In
the legacy KMS implementation, the plane assignment is used to derive
the framebuffer used for mode setting and page flipping.

This also means various high level changes:

State, excluding configuring the cursor plane and creating/destroying
DRM framebuffer handles, are applied in the end of a clutter frame, in
one go. From an API point of view, this is done atomically, but as
mentioned, only the non-atomic implementation exists so far.

From MetaRendererNative's point of view, a page flip now initially
always succeeds; the handling of EBUSY errors are done asynchronously in
the MetaKmsImpl backend (still by retrying at refresh rate, but
postponing flip callbacks instead of manipulating the frame clock).
Handling of falling back to mode setting instead of page flipping is
notified after the fact by a more precise page flip feedback API.

EGLStream based page flipping relies on the impl backend not being
atomic, as the page flipping is done in the EGLStream backend (e.g.
nvidia driver). It uses a 'custom' page flip queueing method, keeping
the EGLStream logic inside meta-renderer-native.c.

Page flip handling is moved to meta-kms-impl-device.c from
meta-gpu-kms.c. It goes via an extra idle callback before reaching
meta-renderer-native.c to make sure callbacks are invoked outside of the
impl context.

While dummy power save page flipping is kept in meta-renderer-native.c, the
EBUSY handling is moved to meta-kms-impl-simple.c. Instead of freezing the
frame clock, actual page flip callbacks are postponed until all EBUSY retries
have either succeeded or failed due to some other error than EBUSY. This
effectively inhibits new frames to be drawn, meaning we won't stall waiting on
the file descriptor for pending page flips.

f2d9a11013 output/kms: Outsource connector state fetching to MetaKmsConnector
As with CRTC state, variable connector state is now fetched via the
MetaKmsConnector. The existance of a connector state is equivalent of
the connector being connected. MetaOutputKms is changed to fetch
variable connector state via MetaKmsConnector intsead of KMS directly.
The drmModeConnector is still used for constructing the MetaOutputKms to
find properties used for applying configuration.

f59d62bc8f kms: Add connector representation
Represents drmModeConnector; both connected and disconnected. Currently
only provides non-changing meta data. MetaOutputKms is changed to use
MetaKmsConnector to get basic metadata, but variable metadata, those
changing depending on what is connected (e.g. physical dimension, EDID,
etc), are still manually retrieved by MetaOutputKms.
