QMP stands for QEMU Monitor Protocol and it is used to query information
from QEMU or to control QEMU.
This implementation will ask QEMU the list of chardevice and store the
path to serial0 in xenstored. So we will be able to use xl console with
QEMU upstream.
In order to connect to the QMP server, a socket file is created in
/var/run/xen/qmp-$(domid).
