Reverse the ordering of the FFT stage to optimize a degenerate radix-4 case.
...
This also happens to increase the accuracy since it appears that the new
ordering is optimal (at least for 20 ms frames), whereas the previous ordering
was pessimal.

Convert tabs to spaces in the opus and celt code.
...
Also reformat some, but by no means all, of the opus
code for line length and three-character indents.
