3426832ac3 hevc: Add support for alternative transfer characterics SEI
The use of this SEI is for backward compatibility in HLG HDR systems:
older devices that cannot interpret the "arib-std-b67" transfer will
get the compatible transfer (usually bt709 or bt2020) from the VUI,
while newer devices that can interpret HDR will read the SEI and use
its value instead.

c3f0357bdf hevcdec: move the MD5 context out of HEVCSEIPictureHash back into HEVCContext
HEVCSEIPictureHash should store only the information extracted from the
bitstream and exported to the higher layer (the decoder or the parser).
The MD5 context is allocated, used and freed by this higher layer, so it
makes more sense for it to also be stored there.
