node_types pxe_boot_path is going to be needed after all, so it has
made a triumphant return.

to use real planetlab nodes instead of fake ones.

This is in support of experiments like Junxing like to run them, with
both plab* and planet* nodes in the same experiment.

Minor tweaks to adding_nodes.

# It's very, very hard to tell which interfaces mii-tool will work on, and
# which to use ethtool on. In fact, in some cases, one tool may report success
# at chaning settings but not, in fact, do anything at all. This script is a
# hack to get around this behavior - it tries both tools, and verifies that
# they did the right thing.

Not quite ready for prime time. I've only tested in on one Linux image so
far. But, I'm checking it in so that I don't lose it. :)

(doh).  Catch the exception and print a more useful error message.

sudo, so that it can clean things like link tracing logs.

change the query to check nodes.node_id instead of nodes.phys_nodeid against
the reserved.node_id.

This means the query now returns FBSD-JAIL for vnodes rather than NULL
for the OS.  I ran the query against every current experiment in the DB
and the only other changes were:

  * plab nodes return RHL_PLAB instead of NULL.  As long as linktest is
    not an osfeature of that image (it isn't) then this fix is compatible

  * pc2000s, which host IXPs, now only return one row in the query.
    Previously they would return a row for "pc17X" and for "ixpN".
    This is probably not what we wanted anyway.

TODO:
Write documentation for it - how to run it, where the logfiles go, etc.

Add hooks for the user to run their own program under test (ie iperf)

Reset condidtions on the Emulab-side LAN before an experiment starts

Get link tracing on plab (probably by starting pcapper with the
program agent)

First, don't retry so many times. The old value of 40 tries was set
before snmpitSetWarn() was around. snmpitSetWarn() itself retries 10
times, so we were trying 400 times before giving up!

Second, if grabbing the edit buffer lock fails, try to find out if
someone else is holding it, and print the owner.

 * rc.config: start rc.motelog

 * rc.motelog: client side motelogger control

between the given type not having enough _available_ nodes and not
having enough _suitable_ nodes.

Also, fix a silly bug in which I was running the type precheck one too
many times. This didn't hurt anything, just took a little bit of time.

relational database.  For now, this is done using some GROUP_CONCATS
and hierarchies of VIEWs, since mysql 5.x does not yet support subqueries in
VIEWs.
