This including redirecting Frisbee output to a logfile.

The "-u" option depends on GNU tar and will do the incorrect thing
with BSD tar.  Thus, try to find "gtar" and use it if available, if
not use bsd tar and print a warning if the rarely used "-u" option is
used.

Fixed a segfault in the new event scheduler

Cleaned up some code that dealt with converting
xmlrpc_c::value_strings to C string constants to avoid further memory
corruption issues.

Also converted AddAgent(), AddGroup(), AddUserEnv() to take 'const
char *' pointers instead of 'char *'s to silence GCC's warnings about
invalid conversions from 'const char *' to 'char *'.

This includes create a large local filesystem (using mkextrafs) if the
target directory starts with "/local".

These changes where suppose to go in with my initial commit, but I
forgot to push from my test node to my devel tree before rebasing and
hanse they didn't make it in.

No changes in functionally.

This prevents it from powering off nodes and generally being quite so
anal about "security violations" in the SECURE boot/load path.  We will
leave this on til we get all the d710 kinks worked out.

This should never have been there in the first place, and I don't want to
carry that hack forward into the post-frisbeelauncher world.

"tb-set-tarfiles" is like "tb-set-node-tarfiles" except that it
distributes the tarfile to all nodes rather than just one and that it
uses frisbee to distribute the file.

These changes involved 1) refactoring frisbee info from images table
into a new table, frisbee_blobs, 2) a new experiment_blobs table, and
3) a new tmcd command so the node knows how to get the files from the
server.

The changes where designed to be general purpose enough to eventually
support:
  1) Distributing arbitrary files (not just tarfiles) to nodes
  2) Perform arbitrary actions on those files
  3) Use arbitrary methods to get the files

As such the tmcd line is as follows:
  URL=* ACTION=*

where URL is currently:
  frisbee.mcast://<ADDR>/<FILE>
for example
  frisbee.mcast://234.16.184.192:18092/users/kevina/home-dir.tar.gz
and when we get around to using a master Frisbee server it could be
  frisbee://*
or it could be a file://, http://, etc.

and ACTION is currently:
  unpack:<LOCA...

Add mechanism to verify TPM generated quotes, require them for the
"securestate" TMCD command, and add some testcases/helper programs in
tools/tspitests.  Add additional SECURE* state machines to stated for
tracking nodes through the secure load and secure boot processes.

I was using v2 fields even when I got a v1 reply.

running the ProtoGENI code. Return AM authorities in ListComponents.

The logic was not quite right.  Also, don't send a SHUTDOWN event when
powering off a node.

Nit.  Noticed this is root's mailbox.

Yes this is silly, but it pissed me off.  Nodes that came up in a system
experiment like hwdown or reloading would wind up TBFAILED because rc.topomap
would fail.  Now boss-install will create a null map when these are setup.
An update script takes care of existing installs.

stated POWER* triggers will now actually do something!
