When getting things working for boss/ops config, forgot to also make changes
here for boss/ops/fs config.

Since we don't currently load the Linux-based tools into an inner elab,
we have to munge DB state in the inner elab so that all nodes use the
standard BSD-based tools.

Reign in a rogue ifdef in the makefile.

The current version of graphviz "dot" appears to put out positions as
floating point numbers rather than integers.  Change to accomodate.

Add missing argument to RecordVlanInsertion().

Don't return 1 from RemoteDoList() on error.  The caller is expecting a list
and not any sort of error.  Instead, on error we tbdie() which is what other
backend modules do on errors.

I cannot seem to get the dependency into the boss and ops ports.

Some of these daemons could go nuts when accounts, etc. disappear while
they are running.

changes and subsequent bug fixes.

auth_mysql module (which is installed under different names depending on the
version).

This could have been done with configure or in boss-install.  I didn't do
the former because configure might get run before apache is installed.  I
didn't do the latter because you would have to remember to re-run configure
if you updated your mod_auth_mysql port.

variables in libtblog_simple and SWIG generated code.

The fix is to libtblog, to get rid of the warning.  The warning from swig
generated code is a swig problem that was supposedly fixed, but apparently
not.  So those warnings remain, and led to the workaround.

The workaround is in shommlists which parses output captured by SUEXEC.
That function captures all output, stdout and stderr, from the command it runs
and presents it in an array.  So if you use it to invoke a perl script that
evokes the "used once" messages, those messages wind up in the array.
showmmlists was not validating that output at all, it just assumed everything
returned was the name of a mail list.  Added some syntactic validation
(aka a regexp) to deal with that.

All we really do is apply one non-standard patch to avoid SSL certificate
mismatches due to "www.emulab.net" vs. "boss.emulab.net".  In older versions
of m2crypto we just patched the installed library files, but the newer versions
get installed as a .egg file, so it is easiest to just patch it while the
port is being built.

I really don't like creating a separate port for this, but the alternative
was to modify the standard port, adding a new option.  That seemed even worse.

install is sufficient to build the Emulab boss software.

Got side-tracked when I noticed that currentusage.php3 dealie in the header
disappears when you have a testbed with no experimental nodes.  Started looking
at the error console in the browser and noticed these...

a node has failed.

* In the main wait loop, I check the eventstate for the node, for
  TBFAILED or PXEFAILED. Neither of these should happen after the
  reboot, so it makes sense to quit waiting if they do.

* I added an event handler to libosload, specifically to watch for
  nodes entering RELOADSETUP or RELOADING, after the reboot. Because
  of the race with reboot, this was best done with a handler instead
  of polling the DB state like case #1 above. The idea is that a node
  should hit one of these two states within a fairly short time (I
  currently have it set to 5 minutes). If not, something is wrong and
  the loop bails on that node. ÊWhat happens after is subject to the
  normal waiting times.

I believe that these two tests will catch a lot of cases where osload
is waiting on something that will never finish.

Fix a problem with the -h flag - I was forgetting to exit()

so that I can add '-p' (show patch) to my public repository.

Also, fixed up an existing config option that had a character
illegal for 'git config' (underscores are not allowed).

Make git-diff-tree generate more context (8 lines).

Also, keep track of the last commit successfully pushed to CVS and start
there when doing a cvspush if the local repo is up to date.  This should
prevent duplicate commits and allow new commits to be pushed before the
central Git repo is updated from CVS.

severely flaky.
