This patch introduces remus-netbuf-setup hotplug script responsible for
setting up and tearing down the necessary infrastructure required for
network output buffering in Remus.  This script is intended to be invoked
by libxl for each guest interface, when starting or stopping Remus.

Apart from returning success/failure indication via the usual hotplug
entries in xenstore, this script also writes to xenstore, the name of
the IFB device to be used to control the vif's network output.

The script relies on libnl3 command line utilities to perform various
setup/teardown functions. The script is confined to Linux platforms only
since NetBSD does not seem to have libnl3.

The last time I posted this script, the feedback was that the script and the code invoking

the script should be in a single patch. So I would suggest doing the same.
