The split looks good to go in now.

For the other two, I think it would be nice to have some
measurements/justification. We have the resampler test to do CPU
measurements (and I see that poljar already did some comparisons that
show soxr to be favourable in the int case at least), but I think we
need to also have a justification based on quality. Any thoughts on
measuring that?

I should also add that for libavresample to be the default
implementation, it needs to be easily available in distributions, and I
think this might be a concern unless the packaging is split off (at
least on my Fedora box, this comes from rpmfusion and not offcial Fedora
packages).
