aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name.
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

79d46cbea6 Quant changes only once per MB so move the corresponding scale factor assignment
out of the block decoding loop. Indeo4 doesn't use any scale table but the quant
level itself as scale. Therefore access scale table only if its pointer != NULL.

so those can be shared by indeo4.

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.

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