update libsndfile to 1.0.28

This updates libsndfile to 1.0.28, the latest release.
Sorry for being so late; thanks to naddy@ for the nudge.

* Add explicit ./configure --options (in --help order)
* Without CPPFLAGS="-I${PREFIX}/include", FLAC includes are not found
* Obsolete doc/dither.html was removed

On some platforms (macppc), the compiler does not understand -Wvla,
so we need a patch for these. Should the patch be made platform-specific?
I would very much like to avoid that, and just drop -Wvla from configure
everywhere, for simplicity.

Tested on current amd64, macppc and armv7; please test everywhere.

There have been a number of fixes since 1.0.28
- I intend to add those in a separate commit.

(Currently, it's 1.0.29pre1)
