Less effective than the approach in vf_tonemap_opencl because there
is no peak detection, but it's still a good idea to implement this.

The two functions are identical. Use the shared LumaCoeffients type too.

When there is no metadata attached to a frame, take into account both
the PQ and HLG transfers, and change the HLG default value to 10:
the value of 12 is the maximum range in scene referred light, but
the reference OOTF maps this from 0 to 1000 cd/m² on the ideal HLG
monitor.

This matches what vf_tonemap_opencl does.

Valid range is [0,8] as stated in aom.git:aom/aomcx.h

Alternatively the parser could be re implemented / redesigned so as to better

This code came originally from gstreamer, where it was added in [1]
as a work-around for the Tegra 3. (The alignment was changed in [2]
as a response to [3], from 32-bit to 16-bit).

gstreamer only used this workaround in the case where the decoder
didn't return a slice-height property, but when the code was copied
into avcodec the conditional got lost. This commit restores the guard
and prefers the slice-height from the decoder when it is available.

This fixes segfaults decoding 1920x1080 h264 and mpeg2 videos on the
NVidia SHIELD after upgrading to Android Oreo.

Fixes some SVQ3 encoded files which fail to decode correctly after 6d6faa2a.
These files exhibit lots of artifacts and logs show "Media key encryption is not implemented".
However they decode without artifacts before 6d6faa2a.
The attatched patch allows these files to successfully decode, but also reject media key files.
