Summary: Move file formats into libsndfile

Initial Comment:
On quality we're behind the curve (libsndfile is widely used and has a better 
test suite than SoX). On quantity we're doing OK: we have several formats that 
libsndfile lacks (and vice versa).

libsndfile's author, Erik de Castro Lopo, has said he's happy for me to put the 
SoX formats into libsndfile, so I'm working on that.

There remains one obstacle to just using libsndfile: Erik won't accept 
proprietary or otherwise problematic formats like MP3, so we need to keep that. 
I'm hoping we can find a way to use the same libsndfile API so that we don't 
need to retain the SoX layer on top (although the way that SoX deals with 
effects and formats may still mean it's desirable to do that).

This is a moderately long-term project, but my goal is to have all the 
non-problematic formats run from libsndfile rather than SoX by the next major 
release; that alone will get rid of a lot of SoX code. libsndfile is about as 
portable as SoX and uses the same license, so it doesn't make extra problems 
for us.

Message:
Progress was that back in 2008 I moved WVE [sic] support into libsndfile.
There are plenty of other simple formats that could be moved, and of course
WAV support could be merged, by adding all WAV features that SoX has but
libsndfile lacks into libsndfile.

The main barrier is that Erik de Castro Lopo has very high standards, but
that means that the result is good, and likely to remain zero maintenance
for SoX devs.

Indeed, libsndfile is not being rapidly developed; that should make it
EASIER for SoX devs to get new formats moved into it.

Message:
Has there been any progress on this? Does anyone still want it?

libsndfile has FLAC/Ogg/Vorbis support since 1.0.18,
and it doesn't look like it will add others any time soon.
