do.

We do not need to lock MaxExtension when just one aggregate.  Also, use
WaitForLock(10) in MaxExtension, IdleData() and Utilization() since it
is nice if the web page asking does not get back a locked error if we
can avoid it.

Needs more thought but this will do for now.

they have been deleted at the IMS; we seem to be losing some of the
delete messages, need to track this down. Also some tweaks to handle
transient RPCs and retry a couple of times.

Previously we forced all Portal datasets to auto approve at the target
cluster, now we let the local policy settings determine that, and return
status indicating that the dataset needs to be approved by an admin.

Plumbed through the approval path to the remote cluster.

Fixed up polling to handle unapproved datasets and to watch for new
failed state that Mike added to indicate that allocation failed.

up throwing the deck chairs off the boat and buying new ones.

1. Add WebTask support for communicating back to the web interface and
   the Geni interface. Especially helpful for the case that a dataset
   needs admin approval.

2. Some changes related to above to make it easier to pass back the
   reason for nor approving.

3. Small semantic change to -C (always create) which I added for the
   Geni path a while back. It now means always create but respect the
   approval decision. In other words, if a dataset would need approval
   cause it is too big, create the dataset but mark it as needing
   approval and send mail. -C used to mean always create and approve.
   The new approach is a better fit for the Portal/Geni path.

This uses the rcmanifest testbed service hook mechanism
(https://wiki.emulab.net/wiki/ClientSideServiceControl); the static,
image-built-in version of it.  It's a pre-hook on the bootvnodes script
that looks for various virt_node_attributes set on the vhost, and maybe
updates the clientside on the vhost from the master repo, or another
repo/branch, if provided.  It can update at first boot (or after a
prepare), or each boot.  Kind of nice for testing.

To ensure this can be run without a lock, don't die on a failed open of
/sys/class/net/$iface/address.  The only reason we'll fail to open here
is if the device has gone away after the initial dir listing, and that
can happen either if our code doesn't hold a global lock while calling
this function, or if some other OS process removes a device.

This happens when called from imagevalidate without the update (-u) option
on a new image. Note that if imagevalidate was called with -u, then the
size would get set before calling imageinfo and we would not have seen a
problem.

This is pretty minimal "support", but it is working.  I have some
uncommitted fixes for event/linktest/iperf, however, as mentioned in
issue #351.
