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

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
as well. And fix static VLC initialization, as ff_ivi_create_huff_from_desc()
used old way to do so.
