662a5b2370 Reorder intra4x4_pred_mode so that we can read/write 4 values at once. 
3-7 cpu cycles faster

5b0fb5244d Store intra4x4_pred_mode per row only. 
about 5 cpu cycles slower in the local code but should be overall faster
due to reduced cache use. (my sample though has too few intra4x4 blocks
for this to be meassureable easily either way)

e1c88a2138 Cut the size of mvd_table by yet another factor of 2. 
The code read/write code itself was 1 cycle faster, overall its
likely more due to cache effects

c4a90caae2 aac: Keep decode_band_types() from eating all padding at the end of a buffer. 
Due to a shortcoming in the AAC specification, if an all zero buffer is
fed to section data decoding it will never terminate. That means without
a buffer exhaustion check decode_band_types() will consume all input
buffer padding. Worse if a get_bits() implementation that returns zeros
when padding is exhausted is used, the function will never terminate.

The fixes that by added a buffer exhaustion check in the sectioning
decoding loop.

d2df291f73 ff_msmpeg4_decode_init() calls ff_h263_decode_init() which calls 
MPV_common_init(), so calling both is redundant and leads to memory
leaks in WMV3/VC-1 decoder. Thus use only the first function in
WMV3/VC-1 decoder initialization.

ff_combine_frame() is called, which allocates ParseContext->buffer if needed,

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.
