Handle PVH domain type in both directions (xen-xl->xml, xml->xen-xl).
And add a test for it.

Does domain_conf.c (virDomainDefFormatInternal) still need to silently
convert VIR_DOMAIN_OSTYPE_XEN to VIR_DOMAIN_OSTYPE_LINUX? In case of
PVH, VIR_DOMAIN_OSTYPE_LINUX was never reported as a valid option...
I'd prefer that we switch to formatting type as VIR_DOMAIN_OSTYPE_XEN and
indicating PV vs PVH with the machine attribute. For back compat we'd need to
continue accepting <type>linux</type> when parsing XML. Other than a lot of
changes to test suite data files, am I overlooking compatibility problems with
such a change?

Ah, I see you fixed up the braces in this patch. Regardless, 'make syntax-check'
should pass with each patch.
