This makes the output compatible with that of pretty much any other
tool that calculates PSNR.

imc: Use correct position for flcoeffs2 calculation
See: 75fd5ce4c1
Merged-by: Michael Niedermayer <michael@niedermayer.cc>
flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
causing problems further down.
This seems to have been copied from imc_decode_level_coefficients in
commit 4eb4bb3 without updating the position.

It asserts that the frame linesize is larger than 37, but it can be
smaller and decoding such frames works.
Before commit cc884a35 src_stride > 7*MB_SIZE was necessary, because the
blocks were interleaved in the tmp buffer and the last block was added
with an offset of 6*MB_SIZE.
It was changed for src_stride <= 7*MB_SIZE to write the blocks
sequentially, hence the larger tmp_step.
After that the assert was only necessary to make sure that the buffer
remained large enough.
Since commit bd2b6b33 s->scratchbuf is used as tmp buffer.
As part of commit 86e107a7 the minimal scratchbuf size was increased to
256*7*MB_SIZE, which is enough for any src_stride <= 7*MB_SIZE.
Also add a comment explaining the tmp_step calculation.

Build system modified
There are several warnings occurring during build after this patch is
applied. The cause of most of these warnings is in that some definitions
needed here are logical part of sbr module and are added in later patches.
When this patches are applied these warnings stop occurring.
The only warning that is added here and is not fixed with later patches
is warning that warns that type mismatch for table ff_aac_eld_window_480.
The reason for this warning is in that ER AAC ELD 480 is not integrated in
to the fixed point implementation at this moment and there is no fixed point
version of this table.
