All three audio format handlers provided only a dummy function. Kill
these as well.

 0.?.? (to be announced) "neural discharge"
 ------------------------------------------
 
+The main change in this release is the major audio format handler
+cleanup which removes some similar/duplicate code and makes it easier
+to implement plugins for other audio formats. Of course, the usual mix
+of other improvements/changes/bugfixes also made it into the release.
+
+       - simplified audio format handlers (some of the handling functions
+         were moved one layer up to the virtual streaming system).
+       - repositioning of mp3 streams is much faster, in particular for
+       - jumping near the end of large mp3 files.
        - permission flags DB_READ,DB_WRITE have been renamed to AFS_READ
          and AFS_WRITE.
        - fix a bug in para_filter that caused decoding of aac files
