[ardour-dev] latest CVS commit

[Paul Davis]

 * a major CVS commit that includes the first pass of changes
   to fix some serious errors in the way ardour handles threads when
   exiting. it also includes a significant fix to make export work when
   sync'ed with JACK

 * I'd appreciate some early testing feedback to confirm that things
   still appear to work. No new functionality is present, just fixes
   for crashes/hangs during exit and silent exported audio files.

 * ardour/gtk: 0.532.0
   libardour: 0.833.0
