Original commit message from CVS: * ext/soundtouch/Makefile.am: * ext/soundtouch/gstbpmdetect.cc: * ext/soundtouch/gstbpmdetect.hh: * ext/soundtouch/plugin.c: (plugin_init): Add BPM detection plugin based on SoundTouch's libBPM. * ext/soundtouch/gstpitch.cc: Allow sample rates until MAX instead of only 48kHz and remove the buffer-frames field from that caps. Clear the remaining samples completely when necessary to get into a clean state again.
