Bus.addWatchFull

Adds a bus watch to the default main context with the given priority (e.g. G_PRIORITY_DEFAULT). It is also possible to use a non-default main context set up using g_main_context_push_thread_default() (before one had to create a bus watch source and attach it to the desired main context 'manually'). This function is used to receive asynchronous messages in the main loop. There can only be a single bus watch per bus, you must remove it before you can set a new one. When func is called, the message belongs to the caller; if you want to keep a copy of it, call gst_message_ref() before leaving func. The watch can be removed using g_source_remove() or by returning FALSE from func. MT safe.
