* Remove custom event queue's IPC management of favour of universal LV2 approach. * Move ipc_manager to FXO. * Fix ipc_manager internal storage memory leak: deallocate entry when IPC object destroyed. * Rewrite lv2_obj::create to be simpler (remove many duplicated code). * Always execute lv2_obj::create under both IPC and IDM mutexes at once (not in non-atomic single-steps). Fixing potential case where concurrency can cause IDM to contain 2 or more different objects with the same IPC key with SYS_SYNC_NOT_CARE (instead of the same object). * Do not rely on smart ptr reference count to tell if the object exists. Use similar approach as event queues as it makes error checkings accurate. * Optimize lv2_event_port by using std::shared_ptr for queue which wasn't allowed before.
