Paul Ferrand	8ee4105b39	Deep change of the background loadingThe goal was to reduce the number of background threads in big sessions (multiple instances) and avoid loading the same file alot on repeated notes (e.g. drum tracks).- All instances use a common thread pool- Each instance has a dispatching job that starts background loader, and a garbage job that clears data that has been unused for some time- The "FilePromise" object has disappeared. Upon request, Voices get a very thin reference-counting handler to the file data. When the handler is released the reference count is decreased and a "last used" timestamp is added to the file.- The background file loading job checks i) if the file is already loaded, or ii) if some other thread is already loading it. If any case is validated, it exits assuming the background loading is already happening.- The garbage job has to be triggered regularly by e.g. the synth. In the RT thread the triggerGarbageCollection() method will check the list of previously loaded file Ids to see if any has not been used for a while. If so, the memory is set to be discarded by a background thread, otherwise it'll wait for the next ping.Only tested on Linux for now.	2020-10-07 00:37:31 +02:00
