I think each of the commit in original series should pass "make check"
before.  But for this revert series, it can't.  I'll take this into
consideration next time even reverting patches.

Regarding to the revert ordering itself: IMHO as long as we do the
first patch last (put "Revert monitor: enable IO thread for (qmp &
!mux) typed" at the end), we should be able to pass "make check" too.
So the correct order should be:

patch 2-4 (in any order, since each of them is only a test case)
patch 1

And, since at it, I just noticed that we could even keep one of the
test ("tests: qmp-test: verify command batching"), but anyway it won't
hurt if we revert that too now.
