Install NFS tracing stuff so we can gather some data.

	* configure, configure.in: Add some nfstrace files.

	* sensors/GNUmakefile.in: Add nfstrace directory to the build.

	* sensors/nfstrace/GNUmakefile.in, nfs.sql, nfsdump2db,
	nfstrace.init.in, nfstrace.proxy: Prototype of scripts to trace
	NFS traffic from experimental nodes and build a list of the files
	that are accessed.

	* sensors/nfstrace/nfsdump2/*: Slightly customized version of the
	nfsdump program.

	* tbsetup/GNUmakefile.in: Install nfstrace control script which is
	used to talk to the proxy on ops.

(e.g., swapin was cancelled before any nodes were allocated)

Change the default hash method to SHA1, MD5 is so passe.

errors NFS hack under FreeBSD.

Added an option to skip the standard tests.

Fix bug in the schelling of parallell experments.

Added two new tests: traffic-gen & linkdelay.

linktest.

before deleting it.

Convert most SNMP interaction to use the snmpit*() library, so that
they get support for retrying failures, etc.

Add new library calls for wrapping bulkwalk() - so now, we will
retry those on error as well. Before, we had the bad behavior than
many functions, like listVlans() would just see empty lists instead
of errors.

When making a new Cisco object, we now test network connectivity right
away, by fetching an OID that should exist on all SNMP devices. Before,
we wouldn't find out we couldn't contact the switch until we actually
did something on it.

Also, make VLAN number choosing go a bit faster by converting it to
bulkwalk() (using the new library function) so we can grab all VLAN
numbers at once.

we're going to remove. We used to do all VLANs in one lock for
performace reasons - however, I'm discovering that the lock can get
held for such a long time when many VLANs are being deleted that other
VLAN operations, such as listing VLANs, can fail. And, it's not
actually that much slower to grab a new lock each time.

they don't by default destroy the partially completed project request data
in the form.

Produces a different message in the web page.

Also fix up a couple of minor firewalled elabinelab issues.

run before the main timeline is started.  Also changed the scheduler
to load events before adding the TIME START events so we can add setup
events before the main timeline.

* Add libadminmfs.pm with routines for entering/exiting and executing
  commands in, the admin MFS.  Node admin and firewall swapout (see
  below) now use this, the image creation process does not yet.

* Add swapout time hooks for running an admin mode process, likely to
  be used to collect swapout time state.  Currently controlled globally
  by two new sitevars.

* Modified node_admin to use the library and added a "-c <command>"
  option to have nodes go into admin mode and run a command.  I don't
  really expect this to be useful, it was just a testing vehicle for
  the library.

2. Improved the swapout process for firewalled experiments.  Largely
   just generalized what we already did for paniced experiments.
   At swapout, firewalled nodes are:

   - powered off
   - set to boot into admin mode and run a disk zapper
   - powered on

  The swapout process then waits for all nodes to successfully complete
  disk zapage, at which point the nodes are nfree'ed as usual....

This is a cheap verification mechanism.  Also install imagehash now with
all the other image tools, it will be used soon.

Factor the Cygwin password authentication hack out of program-agent into libtb, and use it in linktest as well.

The options (HAVE_* enviornment settings) have been there for awhile,
I just found a way to set an environment variable from the makefile.

making into the eventlist.

but probably going to mangle everything again when I get back.
