Apparently at some point in the past, wire info for new nodes moved into
its own table rather than using the switch_* fields of new_interfaces.
For Geniracks or if a certain feature is set, then this new style is used.

However, newscript unconditionally assumed the new format and generated
incomplete entries for non-Geniracks. Newscript now makes the same checks
as newnode.

	usage: runsonxen [-p <parent>] <imageid>
	usage: runsonxen -a [-p <parent>]
	usage: runsonxen -c <imageid>
	Options:
	 -n      - Impotent mode
	 -c      - Clear XEN parent settings completely
	 -a      - Operate on all current XEN capable images
	 -p      - Set default parent; currently XEN43-64-STD

php to the backend newimageid script so that the web interface does not
have to worry about provenance issues. Cleaner too. Also some cleanups to
log image spew.

Change to use the realpath function in the 'Cwd' module instead of
calling realpath via the shell.  The shell command varies in its
reaction to a missing final path component.  On some platforms (Linux,
FBSD10+) realpath reports an error if the final component doesn't exist
on the filesystem.  On others (FBSD < 10), it does not report an error.

The perl function from 'Cwd' emulates the same behavior as FBSD prior to
version 10, which is the behavior the scripts expect.

From here on out, instead of using `realpath`, do the following:

use Cwd qw(realpath);
..
..
my $realpath = realpath($somepath);

we start putting the submap entries into the XML descriptor.

to the portal peers.

Also add locking between the portal daemon and manageremote.

mknewconfig.in now invokes newscript.in directly on the files it generates.

Control and Outer Control interfaces IPs are overwritten by node IP and
outer_control_ip.

This commit is intended to makes the license status of Emulab and
ProtoGENI source files more clear.  It replaces license symbols like
"EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
blocks that contain actual license statements.

This change was driven by the fact that today, most people acquire and
track Emulab and ProtoGENI sources via git.

Before the Emulab source code was kept in git, the Flux Research Group
at the University of Utah would roll distributions by making tar
files.  As part of that process, the Flux Group would replace the
license symbols in the source files with actual license statements.

When the Flux Group moved to git, people outside of the group started
to see the source files with the "unexpanded" symbols.  This meant
that people acquired source files without actual license statements in
them.  All the relevant files had Utah *copyright* statements in them,
but without the expanded *license* statements, the licensing status of
the source files was unclear.

This commit is intended to clear up that confusion.

Most Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the Affero GNU General Public License, version 3
(AGPLv3).

Most Utah-copyrighted files related to ProtoGENI are distributed under
the terms of the GENI Public License, which is a BSD-like open-source
license.

Some Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the GNU Lesser General Public License, version 2.1
(LGPL).

Add metadata_url and imagefile_url.

Also allow pcvm for type.

Also remove the test that requires only one new attribute at a time
Not sure where that came from.

This is in the node type check where we look at what is currently in the
partition they are imaging, and base the set of valid node type on that.
However, if they specify a partition that doesn't currently have an image,
we would previously effectively tell them that the image will not run on
the node type that it is currently running on!

Now we just say "there is no current image in that partition."
