I had a play around with libsamplerate. It's easy enough to put into the Xcode
project and from there it's an easy step to add it to the Audacity dependency
list and remove libresample (making sure that the correct library is linked in).

The only reason that I haven't committed this yet is that I was having a certain
difficulty in getting libsamplerate to build cleanly (one test was also failing
but it's a bug with the test I think). I'll have another tinker with it this week and
see what happens. Now that the configure script is good things should be
easier.

Building native is fine but I'm going to have to modify config.h on the fly to deal
with universal binaries as the endian-ness changes. Not a problem, we do it for
other libraries but the PPC version always needs careful checking.

I presume that for the minute libresample is the preferred library of the two and
should be kept as the default?
