* rocDecode/HEVC parsing: Implemented correct logic to set active VPS, SPS and PPS: start from slice header and up. Added video image size change detection. Fixed slice_segment_address bits calculation in slice segment header parsing. * rocDecode/HEVC: Changed variable naming to Google style. * rocDecode/HEVC: Added VPS, SPS, PPS, and slice segment header content logging functions for debug purposes. * rocDecode/HEVC: Compacted opening bracket lines to keep coding style consistency. * * rocDecode/HEVC: Fixed an issue in profile-tier-level parsing where 44 bits are skipped in an incorrect way using ReadBits() which can only consume 32 bits max. Also formated SPS parsing code by using pointer instead of array element. * * rocDecode/HEVC: Fixed the incorrect array size for sps_max_dec_pic_buffering_minus1, sps_max_num_reorder_pics and sps_max_num_reorder_pics in SPS structure define. * * rocDecode/HEVC: Modified scaling list parsing to make sure we explicitly follow the spec. * * rocDecode/HEVC: Added a few syntax elements to short team RPS structure, updated RPS parsing function and logging function. * * rocDecode/HEVC: In PPS parsing function, use structure pointer instead of structure array element to improve coding clarity. * * rocDecode/HEVC: Compacted the opening bracket lines. No functional changes.
