I think you're probably right that weston_drm_backend_output_config
could hold a pointer to the enum rather than the string.  I've moved
weston_drm_backend_output_config to be a private struct in
compositor-drm.c so this should be doable.

But I think I'm going to opt to leave this change to Giulio as follow-up
work, as I think it needs deeper thought than I'm going to be able to
give it in this patchset.  There was also some discussion about whether
WESTON_DRM_BACKEND_OUTPUT_PREFERRED should be renamed, in which case it
would make sense to do the change in conjunction with that.
