There was a regression reported by Eric Auger before with OOB:
http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html
It is fixed in 951702f39c ("monitor: bind dispatch bh to iohandler
context", 2018-04-10).
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.
