0f8e4dfe6e Increase FF_INPUT_BUFFER_PADDING_SIZE to 64. 
The purpose of this is to give decoders a reasonable amount of buffer to work
with before needing to check for overreads.

c72625f299 Delay translating DCT tokens into coefficients until immediately before IDCT 
This is generally around 12% faster than the prior method of creating a
linked list for each block as tokens are read, but can be anywhere from
8% to 28% faster depending on file and CPU.

7a095ea6fb Do MC and IDCT in coding (hilbert) order 
This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.

This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.

8590e6d529 Strides in Indeo 5 reconstruction filter should be signed, 
this way it works on 64-bit archs too.

4e06acbde4 Fixed a segfault in the DCA decoder with corrupted streams. 
It happens when the number of channels defined by DCAContext:acmod is lower
than DCAContext:prim_channels. In this case, dca_subsubframe() will call
qmf_32_subbands() using s->channel_order_tab[] entries equal to -1.

4784b0922f Do not read beyond end of input in EA-TGV. This should avoid FATE test #362 
result depending on uninitialized data.

FATE result may change for this test.

59b5370f02 Simplify code to set cbp_* 
this seems 1 cpu cycle slower even though we practically just remove code.
Speed loss seems caused by the merge of if(left_type), iam commiting this
anyway as i cant imagine this to be anything but compiler messup.
