Recognize writeback connectors and add 'struct drm_writeback'
objects in order to store them.
These objects are created and stored in a list by the time
that DRM-backend is initialized. This list is updated if a
writeback connector dynamically appears or is disconnected.

Instead of directly creating heads for the connectors in functions
drm_backend_create_heads() and drm_backend_update_connectors(),
add drm_backend_add_connector() that will handle this.
This split makes the code look better and will also make our lives
easier when we introduce writeback connectors.

The function drm_connector_assign_connector_info() should
not be calling functions to handle drm_head, as connectors
and heads are not the same thing after patch "drm-backend:
move connector data from struct drm_head to struct drm_connector".
Move drm_head specific calls to drm_head_update_info(). This
is more in line with the hierarchy of the objects and also

Instead of calling drmModeGetConnector() in drm_head_create()
and drm_head_update_info(), it is better to call it in
drm_backend_create_heads() and drm_backend_update_heads().
Then we can pass the drmModeConnector object as parameter.
This does not change the behavior of the code, but help us
to avoid unnecessarily calling drmModeGetConnector().
Besides that, in the future we will have support for writeback
connectors. And so drm_backend_create_heads() will be reworked
to also populate a list of writeback connectors. To make this
work, we are going to need to know if a connector is of the
writeback type or not, to know if we should call drm_head_create()
or drm_writeback_create(). We can only tell the type of connector
if we have the drmModeConnector object.

This is the first step in order to add support for writeback
connector in Weston. We don't want writeback connectors data
to be stored in 'struct drm_head' objects, as these objects are
used to output content and we should not use writeback connectors
for this purpose.
The writeback connectors will be stored in a new 'struct
drm_writeback', but the connector data is common between
'struct drm_head' and 'struct drm_writeback'.
So move connector data from 'struct drm_head' to 'struct
drm_connector'. This helps to avoid code duplication and makes
the code clearer.

In commit c1e89ba2 "compositor-drm: move connector fields into
drm_head" the function drm_head_assign_connector_info() was
introduced. By that time it was being used only at drm_head
creation, and not to handle connector changes.
In d2e6242e "compositor-drm: create heads for all connectors"
it started to be used also to handle connector changes. In
this scenario we replace old connector props with newer data.
Before doing this, free the old connector data to avoid memory
leak.
Note that as drm_property_info_free() is safe to be called on
a zero-initialized struct, we can call it even in the case where
the head is being created and there are no props yet.

Now that we have a CRTC list in the DRM-backend, we can
iterate through it and look for the CRTCs that do not have
assigned outputs in order to find unused CRTCS.
So we can drop unused_crtcs from struct drm_backend and also
drop the functions drm_backend_update_unused_outputs() and
wl_array_remove_uint32().

There are no 'struct drm_output' for CRTCs that are not active.
Also, CRTC data lives in 'struct drm_output'. This is causing
us some trouble, as the DRM-backend needs to program those
unnactive CRTCs to be off.
If the DRM-backend had the reference for every CRTC (being
active or not), it would make certain functions (e.g.
drm_pending_state_apply_atomic()) more simple and efficient.
Move CRTC data from 'struct drm_output' to 'struct drm_crtc',
as this is the first step to allow the DRM-backend to have
references for every CRTC.
Also, add list of CRTCs to DRM-backend object. Now the
DRM-backend is responsible for allocating/deallocating the CRTC
objects. The outputs will only reference, init and fini the CRTCs
in this list.

We used to use planes_region for the output regions which were being

dpms is turned off in update_complete").

It seem that we skipped to put back in TEXT mode the tty, in case a DRM
device node wasn't present at that time, or it isn't present at all. This
orders the destroy part correctly as to handle that case as well.
As a side effect, as the tty will still be set to GRAPHICS mode we will
require a manual change of the tty number, which might be not possible
on all systems. Properly putting back the tty to TEXT mode should avoid
that, and allows to re-use the same tty no in case the DRM device has
been created at a later point in time.

When dissociating a universal plane from a crtc, we currently don't
reset the current state of the plane (plane->state_cur). When attempting
to use this plane in the future, we can run into invalid memory accesses
due to left over associations with potentially freed drm backend
objects. This commit resets the state of the scanout and cursor
universal planes associated with a crtc.
The following scenario exhibits the problem:
1. Start a (fullscreen) client that is suitable for and assigned to
the scanout plane. The plane's state_cur->output value is set.
2. Unplug the monitor: the scanout plane is "released" but still
maintains the state_cur->output association.
3. Replug the monitor: the plane is deemed unavailable due to an
existing, albeit invalid, state_cur->output value. Note the memory
errors trying to access the drm_output which was freed at step (2).

compositor_accumulate_damage() is called for each output during repaint.
The DRM backend will only set keep_buffer for the surfaces that are visible on
the current output. So a buffer_ref is released that may still be needed. When
the output that shows the surface is repainted, the buffer_ref is gone and the
surface cannot be put on a plane.
Ignore all surfaces that are not visible on the current output to avoid this.

Currently the debug output for 'drm-backend' can be confusing. In the output of
debug_scene_view_print() views may be listed as 'not opaque' but later, during
plane assignment, other views underneath such a view is reported as 'occluded on
our output'.
This happens because weston_view_is_opaque() has some extra checks to determine
if a view is fully opaque, such as 'is_opaque' provided by the renderer for
formats that have no alpha channel.
Use weston_view_is_opaque() in debug_scene_view_print() as well to get more
accurate results.

This moves the creation of the blob to be earlier, to when the damage is

In the test suite we may want to run a DRM-backend test on a
non-default seat, which may not have a input device associated.
Weston's default behavior is to not open if input devices are
not found, as it may cause troubles. For instance, Weston can
open but if no input device is set than the user can not
interact or leave it.
Add flag --continue-without-input to DRM-backend so we can run
these types of tests with no input. Notice that this won't force
the compositor to skip opening a input device if it finds it on
the non-default seat.

All timeline event timestamps are in CLOCK_MONOTONIC already. DRM KMS
timestamps are practically guaranteed to be CLOCK_MONOTONIC too, even though
presentation clock could theoretically be something else. For other backends,
the presentation clock is likely CLOCK_MONOTONIC_RAW due to
weston_compositor_set_presentation_clock_software().
This patch ensures that the recorded vblank timestamp is in CLOCK_MONOTONIC.
Otherwise interpreting the timeline traces might be difficult to do accurately,
since it would be hard to recover the relationship between the presentation
clock and timeline event timestamps.
The time conversion routine is the simplest possible, I don't think we need any
more accurate conversion for timeline purposes. Besides, DRM-backend is the
only backend where the timings actually matter, the other backends are
software-timed anyway.
Since the clock domain of the "vblank" attribute potentially changes, the
attribute is renamed. Wesgr never used this attribute.

If a surface has subsurfaces then the surface itself is in the subsurface
list. To avoid printing it again there is a check to skip the child view,
if it is the same as the current view.
However, this fails when a surface with subsurfaces has two (or more) views:
The check to skip the parent fails for the other view and the two views are
printed again and again until a stack overflow occurs.
So instead check if the parent view of the subsurface view is the current
view. This way, any view that does not belong to a real subsurface is
skipped.
As a side effect, this ensures that each view of the subsurfaces is only
printed once at the correct place in the hierarchy.
