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?).

Fixed typo in API (s/event_notification/event_notification_t/).

Tell user (in README) to configure Elvin library with --enable-threads
to enable threaded API support.

Removed instructions on enabling server discovery feature (now optional).

Document event_register interface changes ("threaded" arguement, which
allows caller to choose between the thread-safe "threaded" API and the
simpler "sync" API).

Mention (in API) that event_notify and event_schedule don't deallocate
notification.

the threaded API; otherwise, use the sync API.  This option allows
multi-threaded programs to access the threaded API, which is thread-
safe.

when backing up (cause of an error that needs to be fixed) since not
all browsers handle this the same. Instead, redraw the form with all
of the original info and a list of error messages at the top.
Conceptually simple change, but it turns out to be a pain to implement
since you need to combine the form and processing code in one page
(well, its just a lot easier to do that), and then change all of the
forms to deal with a "default" value. That is, each different kind of
input tag (text, radio, select, checkbox, etc.) requires slightly
different changes to do that. Lots of forms, lots of entries on the
forms, and its a long slow tedious process. Much nicer though, although
the code is a bit harder to grok. At the same time, I added a lot more
sanity checks of the information being passed in.

The other change is to deal with how browsers handle the back button
on a form thats been properly submitted. Not all browsers use
the cache directives the same, and I was often typing back, only to
have some form get reposted. Thats a major pain in the butt. The way
to deal with that is to have the processor send out a Location header,
which modifies the browser history so that the post is no longer in
the history. You back up straight to the unposted form (if its in the
cache). I've done this to only some forms, since its a bit of a pain
to rework things so that you can jump ahead to a page that spits out
the requisite warm fuzzies for the specific operation just completed.

I've done newproject, joinproject, update user info, newimageid, and
newimaged_dz forms.

emulab address while I'm at it.

an infinite loop rather easily via the NS file TCL hooks. Added a
perl wrapper around parse.tcl called parse-ns, which forks a child to
run the parser. The parser is invoked "nice +10" and the CPU limit for
the child is set to 60 seconds, which should be enough for any parse.
If the limit is exceeded, send email to tbops since this indicates a
big problem or a user being dumb/malicious.

installed.

Second version.

the defs file. Re-arranged some of the existing snippets to make it
somewhat more cohesive, though it could still use a lot more work in
this area. Also, moved all of the remaining stuff about what to copy
from an old boss node (which was the original purpose of the document)
to the end, so that it's more geared toward people setting up their
own boss.

Still needs some documentation (and probably a script for auto-generating)
DNS config files.

consistent 0ms when the intent is no delay, and add an explantion of
what 0ms means (no darling, it doesn't mean that packets travel
through an ethernet wormhole).

the new image stuff. Also fix a minor logic error in dbcheck that was
causing it to break on the failed queries instead of moving onto the
next one.

users by appending a simple path command to the new .cshrc and
.profile when the account is first created. Easiest approach, albiet
an imperfect one.

tb-set-node-os and another explanation in the OS descriptor list
page. Yes, its clear that the distinction between imageIDs and OSIDs
is just plain confusing.

invoked from os_setup, which runs as the user.

modified, even by an admin type.

line in all email from the system. Remove all of the TESTBED: tags
and modify the email function in the web server and perl library to
prepend @DOMAIN@: to the message.

getTrunks: Build a structure representing all of the trunks in the switch
	topolgy
getTrunkPath: Find the shortest path between two switches, across the
	trunks found by getTrunks

Note that the getTrunkPath duplicates some work done in assign. However, we
don't currently have a good way to pass this information from assign to
snmpit, and we need to be able to figure this out anyway, in case snmpit
isn't being called as part of experiment swapin.

These functions should soon be used to pick which VLANs are allowed
across which trunks.

Update pages appropriately. Also cleanup up a few more sub menus.

a node is not allocated (thus putting the .acl and .run file into the
wheel group when capture creates them), return the value of the config
variable TBADMINGROUP (which is flux for us). This makes it easier for
admin people to look at free nodes.

STDOUT, and move around some lines to avoid undefined value
warnings.

since that screws up opera (and is incorrect anyway). Add wrapper code
to the docwrappers to include the html header/trailer code when
doing a printable version, and include the proper style sheet.
