Subject: [PATCH 0/7] media: cedrus: h265: Implement tiles support

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.

Best regards,
Jernej
