This logic was buried deep inside FrameInvariants::new_inter_frame(), but we will need it elsewhere to make guess_frame_subtypes() work. Separate out the static configuration into InterConfig, and pass in the variable state as function parameters. This patch makes new functions to - Determine the index of an output frame in its reorder group - Get the order hint for a given output frame - Get the pyramid level of an output frame - Get the reference frame slot where a decoded frame will be stored - Get whether or not a given output frame will be shown - Get whether or not a given output frame is a Show Existing Frame Not yet converted: - Logic to select the references used by an inter frame This patch introduces no functional changes.
