Fix syntax error.

swapexp: The previous commit, witch added a message about the recovery
action when a swap-modify failed to the top of the email, did not
catch all of the possible cases.  Added the case when the experiment is
not swapped in.

os_setup: Refactored/rewrote os_setup error summary code.  Distinguish
the case when nodes fail to properly load the os and when the don't
boot after loading the os.

Fix bug in libosload when there is an image problem.  The code that checks
if there is an image problem is part of the code that looks up information
on the image.  The problem is that this info is catched so that the next
time this info is looked up the checks are not performed.  Thus, libosload
will attempt to load the image even though there is a problem with the
image.  This will often lead to obscure error messages.  Fixed by using a
special value for when there is a problem with the image.

Fix bug when an experiment has more than 1 image type to load.  Only the
results from one of the image loads will be properly recognized. The
others will be ignored.  This is because the the same file handle is being
used for all the children due to the use of a global file handle glob.
Fixed by changing the glob to a variable and using "new IO::Handle" to
create a new handle for each child.

- Fixed; other logic defects.

- if a node cannot receive ACK's due to firewalled UDP, oprecv will kill
  off bgmon on that node. To discover this, opsrecv detects when a node
  sends many duplicates of the same data to which opsrecv has sent ACKs
  about in the past.

- added parameterized send rate of buffered entries.
- ACK's are checked for a timestamp to prevent old ACKs of same index
  numbers to be interpreted as current.
- common routines have been moved to a .pm file.
- added 'die' API function to force bgmon to exit.

install on an existing image.  Implemented by doing a client-install into
an empty directory via DESTDIR.

pursuit of standards compliance.  Nowhere near complete,
but you've got to start somewhere.
(all tags should be lowercase, all values should be quoted,
including simple things like width="100%").

Don't use "no warnings 'uninitialized'" since that is a perl 5.6+ feature
and some are still using an ancient version of perl.

link.

Also add an Update method.

Change user that receives slice email from the head of the experiment to
the experiment swapper.

Users that create Planetlab experiments will now get email coming back via
the emulabman@emulab.net alias.  The technique is simple:  stash away the
experiment head uid in a file corresponding to the slice's name over in
ops:/etc/mail/plab-slice-addrs.  The silly procmail config file I've committed
here reads this file (if it exists) and forwards mail to the user's email addr
contained therein if the incoming message contains the name of their slice.
There is no install target for this procmail filter;
I hand installed it and hooked it in.

length => $length in os_setup!

that support it.  From DETER.

Fixed bug in summary of failed nodes when there are more than can fit on a line.

Note that it doesn't look like a link.

the decimal point in decimal slots.

* add an "active" flag to the template record, which will be used by
  the user to indicate what templates he wants listed (rather then the
  roots). Basically, the current working templates, rather then a big
  graph.

But I never actually finished that cause it sorta morphed into:

* Added a vis_graphs table to cache the last generated visualization
  rendering in the database so that we do not have to wait so long for:

* Add new buttons to showexp and template_show pages, to display in the
  same page either the settings (current view), the NS file, or the
  visualization (along with zoom in/out buttons).

And now I can go back to that "active" thing I mentioned up above ...

Various tblog changes:

Added message about recovery action when a swap-modify failed to the
top of the email.

Fine tuned os_setup summary error.  Added (possible partial) list of
nodes that fail; if a large number fail only show as many that will
fit on a single line.  Other tweaks.

Flagged assign_wrapper errors of an Invalid OS as user errors.

Also, missing exit(1) following usage message.

rather than the pc hosting the IXP.

Also add option to generated forward file with hosts sorted by IP
(not turned on).
