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
allow us to drop drm_head pointer from drm_connector.

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.

Instead of calling drmModeObjectGetProperties() each time that we need

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.

This commit alters the way that Weston picks a Wayland display socket
name. Instead of using wl_display_add_socket_auto to look for the first
available name in wayland-0, wayland-1, .... to wayland-32, the code now
checks names wayland-1, wayland-2, .... up to wayland-32.
This change is a workaround for a suboptimal behavior of
libwayland-client. If a client program calls wl_display_connect(NULL) and
the WAYLAND_DISPLAY environment variable is not set, then the program will
by default try to connect to 'wayland-0'. This is a problem when a
computer has a running Wayland compositor but is being accessed in some
other fashion, such as through an X session on a different virtual
terminal, over ssh, etc. Client programs launched through those means may
attempt to connect to an unrelated compositor. Changing libwayland
behavior to remove the default would also work, but a) libraries have
stronger backward compatibility expectations b) that would likely break
more people's setups than just changing Weston would.

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.

Currently doesn't exist a standard way to write a weston.ini inside a test.
Here, two new functions `weston_ini_setup` and `cfgln` are introduced to
help the test writer to write a weston.ini file and load it to the test.
And `internal-screenshot-test` is converted to use the new method of write
a weston.ini. This conversion serves as example and initial API test.
The tester needs to call `weston_test_harness_execute_as_client` or
`weston_test_harness_execute_as_plugin` in the same way as before.
The `weston_ini_setup` will fill the setup->config_file with the
correct path to the weston.ini file.
The main design goal is to avoid pre-made or build-made weston.ini(s)
and keep the test as self-contained as possible.

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

After some changes in the exposay layout, the outer padding makes

by the exposay surfaces and to keep distance from the borders

We've been using an inner border of fixed size (80px), but this

Also, it creates a lot of unnecessary space, making the exposay

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).
