        src/sys/arch/xen/xen: privcmd.c

Log Message:
Fix IOCTL_PRIVCMD_HYPERCALL issue which shows up with xen-3.1.3:
some hypercalls results are returned though the error path (depending on
sign, it's an error code or a result), and some results are interpreted in
a special way by the NetBSD kernel (e.g. -1).
Add a 'retval' member to the privcmd_hypercall_t argument, which holds
the hypercall result if it completed without error. The error code
is returned via the usual error path.
Handle the old IOCTL_PRIVCMD_HYPERCALL under COMPAT_40.

While there, make the double-inclusion protection #define match the
convention in xenio3.h and xenio.h.
