modify newwanode to set that for the new wa nodes (control interface).

       control_iface join with node_types, since new nodes have more
       than just expt and ctrl interfaces (ixps). The control_net slot
       is bogus anyway. Note that 'jail' is a placeholder for later.
       A 'fake' interface is not to be confused with veth interfaces; it
       is a psuedo interface like that found between an ixp and the host.

       alter table interfaces add \
		role enum('ctrl', 'expt', 'jail', 'fake', 'other') \
		NOT NULL default 'other' after iface;

install no longer depend on them.

main zone file (which were also being inserted with bad syntax).

(necessary in order to play nicely with vnode_setup).  rc.vinit now
figures out he nodeid based on the file in which libsetup stores it.

* Various improvements to new node stuff, including reworking node
  status updates so that they use the right table, and don't update
  vnodes that are alive (since their watchdog will do this).

* Added renewal code to automatically renew all leases that are doing
  to expire within two days.

* Moved Emulabification directly into the node abstraction.  Now the
  libplab wrapper scripts are all just plain wrapper scripts, instead
  of having the knowledge spread out

* Switched from using a Plab-specific keypair to using the normal
  Emulab one, which makes it possible to use sshtb to Plab nodes.

* Removed node booting code, since vnode_setup takes care of this.

destroyed if necessary, and nodes are allocated into the slice when
needed.  This should be optimized a bit better so that the Plab
manager can obtain as many tickets as possible in one operation,
instead of per node.

that jails do.  sshtb can now handle vnodeid's, and must be given a
vnodeid if it's a Plab node, because the username will differ
depending on this.

really working this time.

I was getting the IP from the hostname, so I switched to the trick
we use on the testbed nodes; use /etc/dhclient-exit-hooks to write
the data into /var/run, and use that in register.sh when the IP=DHCP.

use CONFDIR will work properly. Not tested yet ...

configing the file.

grab that from the bossname using tmcc (be nice if bsd/linux had a
consistent way to get the domainname).

forget to do them all!

the project is different. This is not supposed to happen, but does
when reloading. Sigh.

are necessary to run the Planetlab manager.

service manager and resource broker that works closely with the
control flow through the Emulab experiment swap process.  It keeps all
slice and node data in the DB.  Node allocation automatically unpacks
and configures the node to come up as an Emulab/Plab node when it is
booted (later, via vnode_setup).  It also takes care of other
necessary bits of interfacing with Planetlab, including discovering
which nodes are available, adding new Plab nodes to the DB, and
maintaining status information on Plab nodes.

with views, to give different IPs fro boss and ops to internal hosts
than to external ones.

Needed for Wisconsin.

an interface route when bringing up the interface. To solve this, I don't
do the hostroute optimization (i.e. add the 1st host route as a net route
and add subsequent host routes only if they are different) for directly
connected neighbors.
