Removed hardcoded "boss" from linktest.pl and run_linktest.pl
Changed historical log location.

and wait for linktest events, and integrated it into the perl scripts.

At this point I'm working on small potatoes such as the rc.setup script
to invoke linktest daemon and nailing down where to put platform-specific
stuff such as the ns-linktest build and the customized tb-compat.

Also am testing linktest in cases where I've deliberately inserted an error
to make sure it catches it.

This includes an updated client-install.

However, this is not yet ready for builds due to certain libraries not
present on the nodes and ops. For those I will be writing a static
linked c program to handle the linktest "done" event in both linktest.pl
and run_linktest.pl.

and addded parameter passing the daemon.

Also fixed up the makefile for compilation and installation (client).

described in my final project paper.

is to add HMACs to events to ensure they that events cannot be
injected into an experiment by an unauthorized client.

* The frontend now generates a secret key for each experiment and
  stores that into a file and in the DB.

* Each of the event clients, as well as the event producers
  (scheduler, tevc) have a new -k option to specify the name of the
  file. Two new event library functions were added for clients to give
  the key:

    event_handle_t
    event_register_withkeyfile(char *name, int threaded, char *keyfile);

    event_handle_t
    event_register_withkeydata(char *name, int threaded,
	   		       unsigned char *keydata, int keylen);

* When the library is in possesion of a key, it will generate an HMAC
  and attach it to outgoing notifications. A client receiving a
  notification will compute an HMAC and compare it against the HMAC in
  the notification. If they do not compare, the notification is
  dropped with a warning...

of stuff in the new image. Also added client side install targets
every place I could think of.

and reponds to PROGRAM events. Currently, just start and stop. Start
takes a COMMAND= argument, and allows arbitrary command lines since I
pass the whole thing off to the shell. Caveat; the agent runs as root
and starts the program as root. You can has as many program objects in
your NS file as you like, but each one can be started once; you have
to either stop or wait for the old one to finish before trying to
start again.

system programs. Build two versions of the event library, one for non
threaded programs and another (libevent_r.a) for threaded versions.
Remove all that -pthread goo from all of the makefiles, except for the
scheduler (which is threaded); it gets linked as before, but with
-levent_r instead. If you try and use the threaded API without the
proper link, the library will print an error message and quit.

tbsend.c and tbrecv.c, which are trivial examples of how to send
and receive a sample event.

Also several changes for building on FreeBSD. I've left the older
Makefiles in place so Ian can continue to build in his environmant
(Linux?).
