has been reached. The expt_swapped slot of the experiments table is
also updated on swapmod, so some experiments get more time then they
are supposed to.

This commit is intended to makes the license status of Emulab and
ProtoGENI source files more clear.  It replaces license symbols like
"EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
blocks that contain actual license statements.

This change was driven by the fact that today, most people acquire and
track Emulab and ProtoGENI sources via git.

Before the Emulab source code was kept in git, the Flux Research Group
at the University of Utah would roll distributions by making tar
files.  As part of that process, the Flux Group would replace the
license symbols in the source files with actual license statements.

When the Flux Group moved to git, people outside of the group started
to see the source files with the "unexpanded" symbols.  This meant
that people acquired source files without actual license statements in
them.  All the relevant files had Utah *copyright* statements in them,
but without the expanded *license* state...

will teach me to believe what I read on the web), there is absolutely
no support at all inside. So, a little more wrapping of things and
some code changes, and presto, dataseek() works. Good that we do not
do this very often.

Nit.  Noticed this is root's mailbox.

thankless job but someone has to do it. I'm expecting to finish by the
time Bush 43 leaves office.

stuff into the library since we do that in many places.

As it currently stands, they cannot be automatically swapped because
a paniced experiment will have a firewall node with its control interface
disabled.

disabled, do not run the idle swapper (just exit silently).

I was checking against the idle threshold (ie 2hrs) when I meant to check
against the idle window (5 min), and the result was that no idleswap
warning emails were getting sent. Doh!

choice of idleswap times, it was sending the email before the expt had
even been idle for 5 minutes. So add a check to make sure that they're
idle at least idle_threshold minutes before we send warnings. Meaning, if
the swap time is 30 minutes, and the warning time is 30 minutes, you won't
get a warning at all, instead of warnings every time you've been idle for
1 minute (ie it has been a minute since the last node reported activity).

configurable via a sitevar. Also make autoswap warnings use a sitevar too.

You can adjust (or turn off) idleswap and Max Duration warnings by setting
the corresponding site vars, where 0==no warning.

swap request idle message.

1. Send mail to the swapper, and cc the creator if it's different.

2. Add idleswapping and autoswapping. Going to add warning about pending
autoswap tomorrow.

Should run from cron, about every 15 minutes or so.

Sends mail to idle expts that haven't gotten mail lately. Grabs the magic
constants from the sitevars in the db, and respects idle_ignore. The
messages now get bcc'd to tb-automail instead of tb-ops, too.

With the current settings, it will send each idle expt a message every
four hours (like I've been doing manually, but more punctually and without
going away at night and on the weekend.)

It also has a mode for selecting just one pid/eid, and possibly forcing a
message to get sent. This part will replace the current swap request stuff
in the web (ie, this will be the backend instead of the web page sending
email directly).

(webidlecheck was removed in a separate commit.)

idletimes is the new commandline tool for checking idleness. It shows a
table like this:

PID          EID          Nodes  HrsIdle     Last Activity     Act. type

By default it only shows things that are over an idleness threshold. It
also has a mode to show all expts. Also can show idleness/activity by node
instead of by expt, which has a slightly different table. (s/Nodes/NodeID/)

idlemail isn't finished yet, but I don't want it to hold up idletimes and
the other changes any longer. It doesn't get used by anything yet, of
course.
