dither.diff

Ok, here is the current version.

The only thing that needs improvement is the FIXME in gstaudioquantize.c at the
top.

For some reason when either doing dithering with integer as intermediate format
or dithering + noise shaping with double as intermediate format one gets
harmonics.
When doing dithering only with double as intermediate format (just change the
NS stuff in line 323 to NONE_FUNC for example) there are no harmonics and a
constant, white, noise floor. Does anybody know why this happens?

Would be nice if someone could review the patch :)
