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.

It doesn't depend on hevcdec anymore.

Use ff_hevc_decode_extradata() instead, which correctly only tries
to decode parameter set NAL units and not any other NAL that may be
present in extradata.

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.
