Added standalone support for multiple streams. Added a logging infrastructure. Added a trivial application for testing purposes (dumb-client and dumb-server). Added the capability for running the standalone stub with a tcpdump replay. Added support for changing buffer sizes. Added shell files for experiment management, reset.sh which is to reset the dummynet settings between runs and run-iperf.sh which encapsulates a set of options to iperf.

and libraries.

which are stored in /proj/$pid/images since they cannot go directly
to boss. They need to be copied back of course, but only admins
can create global images anyway.

Use a file to manage the list of ignored/allowed nodes instead of hard coding
them into the source.  The files are:

@prefix@/etc/plab/{IGNOREDNODES|ALLOWEDNODES}

Added inline POD documentation of libtblog.

being taken.

The basic strategy is to have node_reboot (when -p option supplied)
invoke a special command on the node that will cause the shutdown
procedure to run prepare as it goes single user, but before the
network is turned off and the machine rebooted. The output of the
prepare run is capture and send back via the tmcd BOOTLOG command and
stored in the DB, so that create_image can dump that to the logfile
(so that the person taking the image can know for certain that the
prepare ran and finished okay).

On linux this is pretty easy to arrange since reboot is actually
shutdown and shutdown runs the K scripts in /etc/rc.d/rc6.d, and at
the end the node is basically single user mode. I just added a new
script to run prepare and send back the output.

On FreeBSD this is a lot harder since there are no decent hooks.
Instead, I had to hack up init (see tmcd/freebsd/init/{4,5,6}) with
some simple code that looks for a command to run instead of going to a
single user shell. The command (script) runs prepare, sends the output
back to tmcd, and then does a real reboot.

Okay, so how to get -p passed to node_reboot? I hacked up the
libadminmfs code slightly to do that, with new 'prepare' argument
option. This may not be the best approach; might have to do this as a
real state transition if problems develop. I will wait and see.

Also, I changed www/loadimage.php3 to spew the output of the
create_image to the browser.

 * admin MFS is larger and had more problems with simultaneous reboots

 * power command did not support batching anyway (only node_reboot), so
   power ons were performed enmasse, exacerbating problems

Added constant for plab scheduler.

Modifications done for plab scheduler:
* pass thru the UPLOAD/CLEAR events to local elvind so that
  plab-scheduler can get them.
* filter events with <plabsched, 1>
* listen to scheduler==2 evennts also from ops elvind

Convert to a CSS layout, hopefully it should make some workbenchy
things easier.

	* www/beginexp_form.php3: Widen the nscheck window a bit so it
	looks nice.

	* www/common-style.css: Clean out some dead definitions.

	* www/GNUmakefile.in, www/csshover.htc: Some magic that makes IE
	support the :hover CSS pseudo-class.

	* www/currentusage.php3: Tweak the header on the usage table.

	* www/linktest.php3: Drop an extraneous </div>.

	* www/menu.php3, www/tutorial/mobilewireless.php3: Use CSS and

	* www/nscheck.php3: Hide some of the extra stuff.

	* www/style-doc.css: Some styling specific to documentation.

	* www/style.css, www/style-nonmain.css: Update for changes to

Add some code for adding missing files (as determined by the NFS

but getting it committed anyway.

Also a change to the rsync used to duplicate an experiment; do not
preserved permissions.
