* lscpserver: we now only use one instrument loader thread; commands for
  loading instruments in the background wait in a queue to be processed one
  by one to avoid possible race conditions and to improve I/O efficiency
* fixed possible race condition while streaming with multiple disk threads
  by using an own decompression buffer for each disk thread
* libgig: fixed some memory leaks caused by non virtual base constructors
