[Qemu-devel] [PATCH v9 5/7] monitor: remove event_clock_type

[Peter Xu <peterx@redhat.com>]

Instead, use a dynamic function to detect which clock we'll use.  The
problem is that the old code will let monitor initialization depends on
qtest_enabled().  After this change, we don't have such a dependency any
more.
