h264: Add support for alternative transfer characterics SEI

Multimedia / Libav - Vittorio Giovara [gmail.com] - 10 August 2017 09:32 EDT

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.
