Here is an updated version of E-AC-3 spectral extension support.  I have
addressed the issues mentioned in Michael's review in ffmpeg-cvslog.

- should not be expoitable now
- uses smaller int types for context arrays
- got rid of unused variables
- the code to determine copy_sizes and wrapflag is 70% faster
- merged the 2 loops for notch filters
- moved multiplies outside the loop for signal & noise blending
