For the bug, we turned Out-Of-Band feature of monitors off for 2.12 release. Now we turn that on again after the 2.12 release. This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"), meanwhile turn it on again by default for non-MUX QMPs. Note that we can't enable Out-Of-Band for monitors with MUX-typed chardev backends, because not all the chardev frontends can run without main thread, or can run in multiple threads. Some trivial touch-up in the test code is required to make sure qmp-test won't broke.
