Adds support for configuring <hyperv/> flags for domains
running under Xen.
The following flags, making use of QEMU's existing flags, are now
configurable for Xen: vapic, synic, stimer, frequencies, tlbflush and
ipi
Tests have been added validating translation to libxl's viridian flags
Updated docs section on <hyperv/> flags to note support and to specify
which flags work with Xen
