[FFmpeg-soc] AACEnc #if 0 block

[Alex Converse]

In aaccoder.c there is a large block of code like this:
#if 1
lots of code;
#else
similar code;
#endif

What is the purpose of all that else code. Are we trying to move to it? Did
we move away from it and leave it behind? It makes navigating the file much
more painful because it share several function names with the code that is
turned on.

Thanks,
Alex Converse
