60819e694e 10l trocadero: Indeo 5 decoder did not free custom VLCs for macroblock and 
block decoding at exit, so prevent that memory leak now.

9068f36dcc Macroblock and block Huffman code sets are to be used by both Indeo 4 and 
Indeo 5, so make them global and move their initialization to the common place

used old way to do so.
