Allow caller to specify iface in Create() call.

is happening.  Also add a simple perl script to do a little interpretation
of the output stats.

Assign now accepts _urn fields as well as _uuid fields. If no link_type is given, the type defaults to "ethernet". Fixed memory leak in xstr by changing its data structure.

XMLRPC "boolean" but perl does not.

If in geni mode, do not print links from widearea nodes to the 'internet'. These will be printed based on interfaceroles anyhow.

* Add external resource identifiers to the reserved table so we can
  figure out the external node that is mapped onto the local (proxy)
  node.

* Change limit on fixed_iface to 128 chars to accomodate urns.

make a comment instead of 2.

Should run on protogeni.net and boss.emulab.net, fixed issue about resources not being cleared on refresh, added compression option, and other small fixes.  Still need to include support to see 'my resources' and individual slices on the map.

ptopgen now emits 'role="experimental"' on interfaces. rspec-ad.rnc will now accept such advertisements.

phys_nodeid is the target node.  In keeping with the Mike school of thinking
on hierarchy, we only look for one level of subnode.  If a node does have
subnodes, we prompt to make sure the caller really wants to go through with it.

While I was in there, add the -n option to not actually do any DB deletes
or daemon restarts.

While I was in there, add the -S option which first mysqldumps all the
entries we will be deleting.  Maybe this can prevent a catastrophe in the
future.  However, since I didn't make this the default it will likely only
give the caller a greater sense of self-loathing when they do precipitate
the catastrophe ("If only I had used the -S option that Mike the Omniscient
added")

Nice for protogeni experiments.

an optional manifest argument. Only processing the startup command
right now, don't want to put much effort into this until we work out
how the manifest is going to be used and processed in the V2 API.

on the showexp page for geni derived experiments. Got tired of
typing the db queries over and over.

so that they all get done, instead of the just the new slivers. This
is a little extra harmless work, but it is needed cause the mapper
in update mode will reset some of the node state.

This is the sort of thing that should go in an experiment_attributes table
(along with some of the other bits like elab_in_elab, paniced, usemodelnet,
etc.)
