async: Register/unregister aiocontext in graph lock list
Add/remove the AioContext in aio_context_list in graph-lock.c when it is created/destroyed. This allows using the graph locking operations from this AioContext. In order to allow linking util/async.c with binaries that don't include the block layer, introduce stubs for (un)register_aiocontext().
