    tools/hotplug: Add a qemu-ifup script on NetBSD
    
    On NetBSD, qemu-xen will use a qemu-ifup script to setup the tap interfaces
    (as qemu-xen-traditional used to). Copy the script from 
qemu-xen-traditional,
    and install it on NetBSD. While there document parameters and environnement
    variables.
