Anton Khirnov c3f0357bdf hevcdec: move the MD5 context out of HEVCSEIPictureHash back into HEVCContext
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.
