d82e1adc20 hevc: move splitting the packet into NALUs into a separate function 
This function is independent of the decoding context, so we'll be able
to use it in the parser.

ae05b48655 hevc: eliminate the second call to hls_nal_unit() 
Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

This will allow splitting this code for reuse by the parser.

b11acd5732 hevc: remove HEVCContext usage from hevc_ps 
Factor out the parameter sets into a separate struct and use it instead.

This will allow us to reuse this code in the parser.

fd124d8357 hevc_ps: split the code for parsing the SPS and exporting it into the context 
This will be useful in the later commits, where we want to parse an SPS
without having a whole decoding context.
