/*!\brief Interface for AV1 mode search for an individual coding block
*
* \ingroup partition_search
* \callgraph
* \callergraph
* Searches prediction modes, transform, and coefficient coding modes for an
* individual coding block. This function is the top-level interface that
* directs the encoder to the proper mode search function, among these
* implemented for inter/intra + rd/non-rd + non-skip segment/skip segment.
*
* \param[in] cpi Top-level encoder structure
* \param[in] tile_data Pointer to struct holding adaptive
* data/contexts/models for the tile during
* encoding
* \param[in] x Pointer to structure holding all the data for
* the current macroblock
* \param[in] mi_row Row coordinate of the block in a step size of
* MI_SIZE
* \param[in] mi_col Column coordinate of the block in a step size of
* MI_SIZE
* \param[in] rd_cost Pointer to structure holding rate and distortion
* stats for the current block
* \param[in] partition Partition mode of the parent block
* \param[in] bsize Current block size
* \param[in] ctx Pointer to structure holding coding contexts and
* chosen modes for the current block
* \param[in] best_rd Upper bound of rd cost of a valid partition
*
* Nothing is returned. Instead, the chosen modes and contexts necessary
* for reconstruction are stored in ctx, the rate-distortion stats are stored in
* rd_cost. If no valid mode leading to rd_cost <= best_rd, the status will be
* signalled by an INT64_MAX rd_cost->rdcost.
