jailed nodes from veths for plain emulated links between phys nodes,
which we might generally allow at some point for supporting emulated
links (rather than using IP aliases). My plan is to use this im tmcd
to determine what ifconfig returns; no point in returning jailed veth
configuration when the node boots, but should wait until the jail is
setup (this is further complicated by rtabids, but thats another
story).

Some changes Jay wanted,
plus put some of the "H" in HTML (links to papers).

the OSIDs requested. Should work properly with the batch system.

Sheesh. Add link from testbed_stats to experiment_resources to get
better info in showstats.

tbswap can return - they use their return value to communicate some
information. Text is from Chad.

per-experiment instantiation with aggregate data like the number of
swapins, the dates and the like. The other part is the per
swapin/modify stats. These are number of pnodes, links, lans,
etc. Long term, I think we want more precise swapin stats, and with
experiment modify in the mix, we need to have multiple stat records
per experiment, but do not need to duplicate all the stuff in the
other table just mentioned.

To reduce the amount the table size, we cross reference the tables by
index only instead of with pid,eid and the like. We use exptidx to
link experiments, experiment_stats, and the new experiment_resources
table. experiment_resources and stats are linked by another index in
the resources table, which indicates which is the current resource
row. On a modify, a new resource record is created, and the stats
record updated to point to the new (latest) resource record.

Web Changes: Improve showstats and showexpstats. Make them user
accessible so that mere users can see stats for themselves and for
their projects. No ability for mere users (PIs) to look at another
person's stats. Generally, these two pages need more work, but now
they are more useful. I added Show Stats to the user info and project
info pages to display per-usr/proj stats. Add more info in the
showstats display, but the showexpstats display is still not pretty
printed; just the raw tables.

Rename a few fields, add some indexes, and otherwise make some minor
changes that are sure to annoy everyone.

Now fortified with alphabetization!

We can announce it tomorrow.

so we can call it from other places (like the batch daemon.)

entities. All that means is that you can use them independent of
jails by doing something like this in your NS file:

	set link0 [$ns duplex-link $node6 $node9 40Mb 0ms DropTail]

	tb-set-multiplexed $link0 1
	tb-set-useveth     $link0 1

For now, must use OSID FBSD47-JAIL, but that will change when I create
new images. The fallback without useveth is IP aliases like before,
which is nice cause that will work on Linux too.

There are some other minor cleanups included.

to interfaces) so that we return the MAC of the virtual interface not
the physical interface.  I do not much like this arrangement.  We
store veth interfaces in another dynamic table, so must join with both
interfaces and veth_interfaces to see which iface each linkdelay
corresponds to. If there is a veth entry use that, else use the normal
interfaces entry. Maybe we should use the regular interfaces table,
with type veth, entries added/deleted on the fly. I avoided that cause
I view the interfaces table as static and pertaining to physical
interfaces only, but the current arrangement does not scale well
(although if it only ever has to scale to veth_interfaces, so be it).

I am committing this now so I can install my own assign_wrapper and
have it work against the DB on boss (my tree is heavily stats hacked).

 - Use a new example, that has a lan in it
   - including an updated picture and an updated expt report email msg.
 - Update the loop example to make a LAN, since it is non-obvious, and
   very handy.
 - Make LANs in general more obvious.
 - Make Netbuild more obvious.
 - Update our "current images" to FBSD47 and RHL73.
 - Change "the Testbed" to "Emulab" everywhere...
 - Make the difference between control net and exptl. net more obvious,
   and add links to the faq questions in a couple of places.
 - In the part that talks about getting help, remind them to keep tbops on
   each message.

There's still a lot more to be done with the docs, but this is a start, at
least.

we can create emulated links that use the veth device instead of an IP
alias. Without linux support, mere users would not get to choose this
option since it will only work between FreeBSD boxes with veth
support.
