Namely, attempting to upload a project-wide shared image from a node in
an experiment in a subgroup of the project.

Includes support for adding new nodes/interfaces/interface-types/wires.
Also includes sample xml files.

Disabled link buttons on the slice canvas for managers without links. Switched delay node to be at the end of the draggable nodes on the slice window. Dragging a manager onto the canvas now adds a node or prompts the user to add one. Bolded the map markers.  General bug fixes various places.

frisuploadd will move <foo>.tmp to <foo> when it completes. Since create_image
monitors the size of the former, it might get an undefined value if it checks
the size right after it have been renamed. Compensate.

Attempts to load an image from a subgroup of a project didn't work because
I was only setting the primary group ID based on the node's experiment's
project. Now we use setgroups() to establish all groups that the swapper
of the experiment belongs to.

It goes in $TB/etc/extracerts.bundle.  Right now, there's no way to
similarly maintain local CRLs, CA blacklists (certificates _not_ to allow
from the CH), or to refuse certificates from the CH by default, but we
can find a way to do those things if there's any need.

If nodes.pxe_boot_path is set to '/tftpboot/pxelinux/<something>', then
dhcpd_makeconf will set the (pxeboot) filename to /tftpboot/pxelinux.0
and symlink the node's config file (/tftpboot/pxelinux.cfg/<mac>) to
/tftpboot/pxelinux.cfg/<something>.

In other words, we can customize pxelinux to some small degree, using one
of some small number of pre-existing configurations. We were using pxelinux
before for plab-in-elab and we will also need it for loading WinPE for
configuring Windows7 images. For the latter we will set the pxe_boot_path
to /tftpboot/pxelinux/winpe.

Anyway, ideally we would allow the user to specify a pxelinux config file
through the NS file, but need to think about the implications of that some
more. Small steps...

Also make sure that datetime in XML is rfc 3339 compliant (tack on Z
to indicate GMT).

indicate GMT).

Right now the servers that are spawned have just the primary gid of the user.
Determining the right set of gids requires rummaging around in the DB for the
Emulab config.

The mfs directory has been moved to its own public repository:

For ease of debugging.

Fixed rspec_version stuff in AM calls.  Fixed if user opens Slice Window before slivers are retrieved, it doesn't update when slivers are gotten.  Gets slivers from AMs outside ProtoGENI after restart of Flack. PLE had a bug where they return the same node with different component_ids from PLC which will need to be fixed before this works entirely. Changed method of parsing RFC 3999 dates. Changed behavior of SliverCreate/SliverStatus to all run in parallel.

There is no such function as splice on strings in JavaScript. Therefore we have to make sure we do the equivalent. Notified library authors in a bug report.
