Biggest change is that AioContext locking got removed, but no changes required other than dropping the calls to acquire and release it. As a consequence, the single parameter for the bdrv_graph_wrlock() call got removed which also required adaptation. QAPI docs became stricter requiring to document all members. Other minor changes: - Single parameter from migration_is_running() was dropped. - qemu_mutex_(un)lock_iothread() got renamed to bql_(un)lock().
