glib: add compatibility interface for g_get_monotonic_time()
This patch fixes compilation errors when building against glib <2.28.0

The QXL driver is calling QXL_IO_UPDATE_AREA with an empty area. This
is a guest bug. The call is async and no ack is sent back on guest
bug, so the X server will hang. The driver should be improved to avoid
this situation and also to abort on QXL_INTERRUPT_ERROR. This will be
a different patch series for the driver. However, it is simple enough
to keep qemu running on empty areas update, which is what this patch
provides.

s390x: Drop not used allow_hotplug in event-facility
s390-sclp-event-facility creates s390-sclp-events-bus
and immediately sets its allow_hotplug field to 0,
which is NOP since it's already 0 by default.
Also since BUS is not hotpluggable, it's not possible
to call SCLP_EVENT{ DeviceClass::unplug } callback
from qdev_unplug() making this unreachable code,
so drop it as well.
