Makes the client's life much easier to identify between multiple remote
outputs. xdg_output is advertising (in later versions) the head name,
but in case we have different plug-ins or multiple remote
outputs created, it would only repeat/advertise the same name
for all (remoting) outputs.
This instead uses a string that uses both the connector and name to
derive a more easier identifier a client can choose from.

kiosk_shell_destroy() will free up weston_desktop, but still keeping
listeners set-up (keyboard/seat/caps), which will fire
when the the compositor is stopped/shutdown by clients still connected.
This patch maintains a list of seats and uses it to remove any listeners

appear to be using weston_desktop_destroy() in their respective destroy
parts.
This avoids an illegal access happening when calling one of the

As we've started to use Weston's default screenshooter

Until now we had two different protocol extensions: one for the
test suite screenshooter and other for the screenshooter client.
As they are identical and this won't change, make the test suite
use the same protocol that the screenshooter client uses.
Besides the cleanup, this change will also allow us to use the
DRM writeback screenshooter in the test suite, as the test suite
implementation is hardcoded to use a renderer based screenshooter.

We have two functions with the name weston_screenshooter_shoot():
1. screenshot protocol function that the screenshooter
client uses to request screenshots to the compositor
2. libweston function used by the compositor to take
screenshots as requested by the screenshooter client
Until now we had no problem with that, but in the next commits
we are going to use the screenshot protocol in the test suite,
which is also user of libweston. So rename screenshot protocol
function to weston_screenshooter_take_shot() to avoid the conflict.
For consistency, also rename screenshooter_shoot() to
screenshooter_take_shot() in compositor/weston-screenshooter.c

There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.
For instance, in the DRM backend we plan to add a writeback
connector screenshooter. In case it fails for some
reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

If weston.ini is not setting background-image path,
then desktop-shell sets ${DATDIR}/weston/pattern.png
as background. However in this case width and height
is set to 1 during background config and is being
scaled to avoid allocation of buffer.
This behavior is not right. Along with background-image
path, we should also check if background-color is set.
If background color is set, then only scale 1x1 buffer.
This would allow to set pattern.png as default wallpaper
of weston correctly, if background-color is also not set
in weston.ini file.

Ubunut Xenial is the only mentioned distribution that does not provide a

while ago.
Libdrm 2.4.95 also introduced DRM_CLIENT_CAP_ASPECT_RATIO,

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.

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.

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.
