Fix dump_modes when requesting multiple modes.
...
dump_modes() was re-using a loop index for a loop nested inside
the main one, so it would only output the struct for the first
one.

Energy quantization tuning.
...
Prediction coefficient now depends on the frame size. Also, the pdfs and means
have been adjusted and better quantized. This breaks compatibility of course.

...
by POSIX. The other _t types that are not part of the API are still there
for now. Also, got rid of all that was left of the 64-bit types.

creating the mode. This means that the same mode can be shared for mono and

to make sure that stereo coupling is done at the band level. Previously
the stereo coupling was done all at once, but there were all kinds of
interactions with the prediction and folding.
