[libvirt] [PATCH] xen: work with xen 4.0.1 headers

[Eric Blake]

* src/xen/xen_driver.h (includes): Include main xen headers
here...
* src/xen/xs_internal.c (includes): ...rather than in just one of
the sub-drivers.

I'm waiting for an ACK before pushing this, but it sure seems
pretty trivial.  I don't know why the xen 4.0.1 headers of rawhide
are different from the xen 3.4.3 headers of Fedora 13 (translation:
something used to implicitly include xen/xen.h in the older headers,
but no longer does in the newer xen, but I didn't bother to figure
out where the inclusion chain differs).

Tested on F13 and rawhide; fixes the MAX_VIRT_CPUS undeclared issue
that was occurring on rawhide.
