shared node. Added for libosload_new, which was calling a non-existent
predicate function.

OSinfo and Image into a single object for the benefit of the perl
code. The database tables have not changed though.

Make all arguments to GetEventState() optional.  HasStartupAgent() look
in the program agent and event list, for programs that have been
scheduled to start at time=0.

to new nfsmounts slot, which is an enum. For the moment we keep them
in sync but still check nonfsmounts.

This will be used by the power command to tell it to try to power on a
machine that fails to "cycle". ipmitool (or IPMI) seems to fail by default
if you try to cycle a powered-off node.

derived from the PHP code.

Via control network.

to check the reservation_name in the nodes table; if reserved_pid is
set but reservation_name is null, it was prereserved via the web interface
not via the prereserve command line tool. In this case, we never clear
the pre-reserve, someone has to do that via the web interface.

It was checking the count of database rows (which would always have
been 1), not the count of free addresses.

When creating a pre-reserve, new -n option to specify a name for the
reservation, defaults to "default". All other operations require an
-n option to avoid messing with the wrong reservation. You are not allowed
to reuse a reservation name in a project, of course. Priorities are
probably more important now, we might want to change the default from 0 to
some thing higher, and change all the current priorities.

For bookkeeping, the nodes table now has a reservation_name slot that is
set with the reserved_pid. This allows us to revoke the nodes associated
with a specific reservation. Bonus feature is that when setting the
reserved_pid via the web interface, we leave the reservation_name null, so
those won't ever be revoked by the prereserve command line tool.

New feature; when revoking a pre-reserve, we now look to see if nodes being
revoked are free and can be assigned to other pre-reserves. We used to not
do anything, and so had to wait until that node was allocated and released
later, to see if it could move into a pre-reserve.

Also a change required by node specific reservations; when we free a node,
need to make sure we actually use that node, so have to cycle through all
reservations in priority order until it can used. We did not need to do
this before.

Overall pre-reserve handling is unchanged; if there is a another higher
priority type pre-reserve, it will be filled first. Moral, be sure to think
about the priority argument, which you had to do anyway.

need node_reservations for, well, node_reservations.

unlocked checked, used in the Geni getticket() routine.

Need to change this entirely.

Stopgap solution - somewhat risky.  What we would prefer is a solution
that requires users to authenticate and grab a new keyed URL each time
they want to connect to a console.

change had some problems.

* Various UI tweaks for profile versioning.

* Roll out profile versioning for all users.

* Disable/Hide publishing for now.

* Move profile/version URLs into a modal that is invoked by a new Share
  button, that explains things a little better.

* Unify profile permissions between APT/Cloudlab. Users now see just two
  choices; project or anyone, where anyone includes guest users in the APT
  interface, for now.

* Get rid of "List on the front page" checkbox, all public profiles will be
  listed, but red-dot can still set that bit.

* Return the publicURL dynamically in the status blob, and set/show the
  sliver info button as soon as we get it.

* Console password support; if the aggregate returns the console password,
  add an item to the context menu to show it.

* Other stuff.

Previously it was the creation stamp for the hash. By making it the
expiration time, we can do different times for different nodes.

Note that there is no serious compatibility issue with re-purposing
the DB field. It is almost always zero (since they are only valid
for 5 minutes) and if it isn't zero when the new code is installed,
the hash will just immediately become invalid. So what? Big deal!

Significant hackary involved. Similar to exports_setup, there is a boss-side
script and an ops-side script to handle creation and destruction of the ZFS
clones that are used for the NFS filesystem. The rest was all about when to
invoke said scripts.

Creation is easy, we just do a clone whenever the TBAdminMfsSelect is called
to "turn on" node admin mode. Destruction is not so simple. If we destroyed
the clone on the corresponding TBAdminMfsSelect "off" call, then we could
yank the filesystem out from under the node if it was still running in the
MFS (e.g., "node_admin -n off node"). While that would probably be okay in
most uses, where at worst we would have to apod or power cycle the node, we
try to do better. TBAdminMfsSelect "off" instead just renames the clone
(to "<nodeid>-DEAD") so that it stays available if the node is running on
it at the time, but ensures that it will not get accidentally used by any
future boot. We check for, and destroy, any previous versions for a node
every time we invoke the nfsmfs_setup code for that node. We also destroy
live or dead clones whenever we call nfree. This ensures that all MFSes
get cleaned up at experiment swapout time.

Keeping them up to date throughout the node lifecycle is not a lot of fun...

* Do not "reset" taint states to match partitions after OS load.

Encumber node with any additional taint states found across the
OSes loaded on a node's partitions (union of states).  Change the
name of the associated Node object method to better represent the
functionality.

* Clear all taint states when a node exits "reloading"

When the reload_daemon is finished with a node and ready to release it,
it will now clear any/all taint states set on the node.  This is the
only automatic way to have a node's taint states cleared.  Users
cannot clear node taint states by os_load'ing away all tainted
partitions after this commit; nodes must travel through reloading
to get cleared.

If a user tries to os_load a virtnode who's physnode is not tainted,
skip (deny) it.  Also add a second safety check in Node->OSSelect to
enforce node tainting.

while creating a set ov new vnodes. Also some minor cleanup.
