A longstanding pain point of the drm VOs is the relative lack of state sharing. While drm_common does provide some sharing, it's far less than other platforms like x11 or wayland. What we do here is essentially copy them by creating a new vo_drm_state struct and using it in vo_drm and context_drm_egl. Much of the functionality that was essentially duplicated in both VOs/contexts is now reduced simple functions in drm_common. The usage of the term 'kms' was also mostly eliminated since this is libdrm nowadays from a userspace perspective.
