Although unlikely, a 8192x4320 video (where macroblocks are 16x16), would contain 138240 macroblocks on a frame. As per the H264 specification, 'first_mb_in_slice' can be up to PicSizeInMbs - 1, so increase the size of the field to 32-bits. Note that v4l2_ctrl_h264_slice_params struct will be modified in a follow-up commit, and so we defer its 64-bit padding.

On SLICE_BASED mode, a single slice is expected per OUTPUT buffer, and therefore 'start_byte_offset' is not needed (since the offset to the slice is the start of the buffer).

The purpose of the redundancy is to make the codec fault-tolerant in network scenarios. This is of course not needed to be reflected in the V4L2 controls, given the bitstream has already been parsed by applications. Therefore, move the redundant fields to the per-frame decode parameters control (DECODE_PARAMS). Field 'pic_parameter_set_id' is simply removed in this case, because the PPS control must currently contain the active PPS. Syntax elements dec_ref_pic_marking() and those related to pic order count, remain invariant as well, and therefore, the fields dec_ref_pic_marking_bit_size and pic_order_cnt_bit_size are also common to all slices.

This is the case if SPS scaling_matrix_present_flag or PPS pic_scaling_matrix_present_flag are set, and should be handled by applications. On one hand, the PPS bitstream syntax element signals the presence of a Picture scaling matrix modifying the Sequence (SPS) scaling matrix. On the other hand, our flag should indicate if the scaling matrix V4L2 control is applicable to this request. Rename the flag from PPS_FLAG_PIC_SCALING_MATRIX_PRESENT to PPS_FLAG_SCALING_MATRIX_PRESENT, to avoid mixing this flag with bitstream syntax element pic_scaling_matrix_present_flag, and clarify the meaning of our flag.
