b9f76d19d8 hevc_ps: make sure failing to decode an SPS always returns an error 
Some of the goto err clauses do not set the error code. It seems better
to fall back on INVALIDDATA instead of adding it everywhere explicitly.

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.

0625a38066 hevc_ps: check overflow and test alternate syntax 
Some streams were found to have what appeared to be truncated SPS.
Their syntax seem to be valid at least until the end of the VUI, so
try that syntax if the parsing would overflow the SPS in the
conforming syntax.
