SA of the caller. This means we call out to the Emulab newgroup script
to create a group if it does not exist. We also have to reset the
groups of the GeniUser once we know the SA. 

Other small changes:

* Minor module shuffling.
* Use GetSiteVar() from emutil instead of libdb
* Get rid of obsolete code referring to the old reservation holding
  experiment.
* Cleanup logfiles in the workdir.
* Capture output from the mapper and reformat error logging to make it
  more apparent to the caller what went wrong.
* Change call to GeniSliver::Node->Create(); pass in the node object.

TODO: Come back soon and fix the underlying problem which is the use of 'foo || bar' to get attribute values in perl.

starting any one of our scripts can take a second or two. That time is
spent including and compiling 10000s of thousands of lines of perl
code, both from our libraries and from the perl libraries.

Mostly this is just a maintenance thing; we just never thought about
it much and we have a lot more code these days.

So I have done two things.

1) I have used SelfLoader() on some of our biggest perl modules.
   SelfLoader delays compilation until code is used. This is not as
   good as AutoLoader() though, and so I did it with just a few 
   modules (the biggest ones).

2) Mostly I reorganized things:

  a) Split libdb into an EmulabConstants module and all the rest of
     the code, which is slowly getting phased out.

  b) Move little things around to avoid including libdb or Experiment
     (the biggest files).

  c) Change "use foo" in many places to a "require foo" in the
     function that actually uses that module. This was really a big
     win cause we have dozens of cases where we would include a
     module, but use it in only one place and typically not all.

Most things are now starting up in 1/3 the time. I am hoping this will
help to reduce the load spiking we see on boss, and also help with the
upcoming Geni tutorial (which kill boss last time).

internally, as the primary key in the tables, but the CM/SA APIs no
longer use them. The CH still accepts them for now. We can probably
stop putting them into manifests and advertisements at this point as
well. 

For slivers, stop using the uuid of the node as the uuid of the sliver
itself; generate a new one. As above, this is cause the uuid is the
primary key in the table, but the URN is what we use for lookups,
etc.

backwards compatible with old SAs and CMs until new code makes it
out to everyone. So the CM now does a version check at the target SA,
and if an old version 1, use the bogus self signed cred. If the SA is
version 1.01, send a proper sliver credential.

In the SA, accept older bogus credential for now, but start accepting
the new sliver credential, and apply more stringent checks.

rid of self signed certs that are bogus (for other authorities that
are not us).

the vinterface instead of the interface.

shared nodes.

DB so that when the ticket is redeemed (and we run the mapper again to
actually insert the DB state), we get the same ifaces. We really
cannot depend on assign to pick the same ifaces each time. Sure hope
this works!

<disk_image
   name="urn:publicid:IDN+emulab.net+image+GeniSlices//UBUNTU91-LAMP" />

In other words, allow "GeniSlices" for the project, so we can add
images to be used from the rspec.

impotent, except that actually nalloc the nodes, and retry if the
nodes are sucked up by someone else inthe meantime.

Also, in the CM, add better ssh key checking.

We will deal with Resolve versioning issues later.

Add support for disk loading (disk_image tag).

Note that command line arguments for ptopgen are tweaked slightly so that after '-g' for GENI, you must enter a version number. Changed invocation in GeniCM. Also, tweaked rspec definitions to make it conform to reality on the ground inside of our system as it gets implemented.

Formatting with the suggested coding style and added support for max_components policy and its exception credentials.

keeping it as xml element makes it easier to access when required. Otherwise, we need to Parse and serialize many times unnecessarily.

1) Exception for allow_externalusers policy
2) Exception for Max_sliver_lifetime policy
3) Bug Fix in GeniXML.

Bug fix to UpdateManifest(); need to pluck the vlantag out of the
linked lan (the underlying vlan when its an encapsulated link).
