There were various problems with importer loader code. One defect was that it kept managing a single global list of available importers and marking which one is currently used on it. This made it not work correctly for multiple sink instances in single process and was not thread safe. This commit changes importer loader code into a GstObject subclass, which keeps its own list of importers per instance and unlike before makes it possible to free this data from memory when destroyed. Now only open modules are kept always in memory until process finishes since we cannot unload them once loaded anyway.
