2d09cdbaf2 indeo5: check tile size in decode_mb_info().
This prevents writing into a too small array if some parameters changed
without the tile being reallocated.

00a1cdd264 Place some START_TIMER invocations in separate blocks.
This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement.  START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

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.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as
hidden.

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.
