ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

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