src/xend_internal.c, src/xend_internal.h,

src/xs_internal.c, src/xs_internal.h: The interface
between xen_unified.c and its underlying driver now uses
a custom structure (struct xenUnifiedDriver) instead
of reusing virDriver.
* src/xen_unified.c: virDomainLookup* functions in Xen
now throw VIR_ERR_NO_DOMAIN if the domain does not exist.
* src/xs_internal.c: Fix indentation.
