Now that we have full and stable HEVC uAPI, let's implement last big missing piece of HEVC in Cedrus - tiles support. This is done in last patch. Before that, there are bug fixes (patch 1 & 2, previously submitted separately in [1]), error handling improvements (patch 3, 4) and added helper for dealing with dynamic arrays (patch 5). These patches are based on top of [2]. Final fluster score with this series is 125/147. 11 bitstreams are MAIN10, which is not yet properly supported. 5 bitstreams need better memory management with auxiliary buffers (wip patches exists). 4 are too big and 2 probably fails due to ffmpeg implementation. Used ffmpeg source is in [3]. Note - Cedrus driver currently supports only one slice per request since HW takes data for 1 slice only. This can be improved by loading data for next slice automatically after HW signalled end of decoding. Something for later. Please take a look.
