drm_hwcomposer: Tracking of the DRM FB objects using RAII DRM framebuffer objects must be kept registered in DRM/KMS while used for scanning-out (After atomic commit applied for processing by display controller and until next atomic commit is applied for processing). Existing logic for tracking current state is overcomplicated and needs to be redesigned. Also further developing of drm_hwc will require migration to asynchronous atomic commit, so additional asynchronous FB cleanup logic must be created. Buffer caching logic will also benefit from this. With the RAII all further changes will be less painful and more robust. By this commit I also renamed DrmGenericImporter to DrmFbImporter: 'Fb' word is present in most of existing composers (android and linux) so it will be easier to compare different implementations.
