Introduces hot plug/unplug support for the vfio-ap device. Note that only one
vfio-ap device can be attached to the ap-bus, so a vfio-ap device can only be
hot plugged if the '-device vfio-ap,sysfsdev=$path_to_mdev' option is not
specified on the QEMU command line.

Please note: During testing of this patch I discovered a bug whereby an
attempt to plug in a vfio-ap device subsequent to an unplug of the
device will result in the following error:
error: Failed to attach device from /root/conf/vfio-ap.xml
error: internal error: unable to execute QEMU command 'device_add': No
'ap-bus' bus found for device 'vfio-ap'
