deebfd99e3 backend-drm: get the drm device from the output
If we have multiple drm devices, we cannot use the drm device from the backend,
because we would only get the primary device and not the device of the output.

101c0f6b8b backend-drm: get the fb using the device instead of the backend
The fbs are specific to the device on which they will be displayed. Therefore,
we have to tell which device shall be used when we are creating the fb.

0d967bd7f4 backend-drm: extract device from backend
Extract the kms device from the backend to allow a better separation of the
backend and the kms device. This will allow to handle multiple kms devices with
a single drm backend.

00b74293e8 backend-drm: use pixel format to print gbm format
The gbm_format is the same as the drm format used by the pixel format.

Print the format name using the pixel format in the error message to make the
error message easier to understand for humans.

bb55d86300 backend-drm/drm-gbm: gbm_device_destroy on an invalid gbm device
When EGL initialization fails (failure to create a GLES3 or GLES2
context) we will end up calling gbm_device_destroy() twice, once
in init_egl() and once in the drm_backend_create() error path.

Given that we should also take care of properly destroying the gbm
device when we don't have any inputs for instance, mark the gbm device
as NULL to avoid calling gbm_device_destroy() once more when destroying
the DRM-backend.

567cc92797 backend-drm: add DRM_FORMAT_MOD_INVALID to modifier sets when no modifiers are supported
From now on, when we can't know the modifiers supported for a certain
format, we add DRM_FORMAT_MOD_INVALID to its modifier set.

There is some parts where nothing is being added an others where
DRM_FORMAT_MOD_LINEAR is being added, so fix them.

f767302729 backend-drm: fix slightly wrong comment about allocating with no modifiers
In create_gbm_surface() we may allocate with no modifiers in the
following situations:

1. old GBM version, so HAVE_GBM_MODIFIERS is false;
2. the KMS driver does not support modifiers;
3. if allocating with modifiers failed, what can happen when the KMS
   display device supports modifiers but the GBM driver does not, e.g.
   the old i915 Mesa driver.

The comment was only stating the third situation, so add the other two.

3459bad63d backend-drm: move code that creates gbm surface to a separate function
The function drm_output_init_egl() is too big, so move the code to
create the gbm surface to a separate function: create_gbm_surface().

Also made some minor style changes to the code that has been moved, in
order to improve readability.

7466309c12 backend-drm: start to use weston_drm_format in drm_plane
In commit "libweston: add struct weston_drm_format" struct
weston_drm_format and its helper functions were added to libweston.
Also, unit tests for this API have been added in commit "tests: add unit
tests for struct weston_drm_format".

Start to use this API in the DRM-backend, as it enhances the code by
avoiding repetition and ensuring correctness.

db6e6e1ec5 gl-renderer: Replace window-create args with struct
gl_rendererer's output_window_create has a lot of arguments now. Add a
structure for the options to make it more clear what is what.
This is in preparation for adding bare-integer arguments which are ripe
for confusion when passing positional arguments.
