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.
Based on the H264 SEI implementation.
This will be mainly useful once support for SEI messages that can be
used by the hevc parser are implemented, like Picture Timing.

This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.
Today, we track the short term RPS size for DXVA, but only if the
SliceHeader RPS is being used. Otherwise it's left uninitialized.
NVIDIA's VDPAU implementation requires that the size be accurately
tracked even if an SPS RPS is being used. In this case, it's really
counting the size of the RPS idx information, but you end up with
mangled output if the value is not accurate.
VDPAU also needs the size of the long term RPS.

ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.

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.
And use unsigned datatypes.
Otherwise it would overflow.
