deleted, they still remain in the user table with a status of
"archived", but since all the queries in the system now use uid_idx
instead of uid, it is safe to reuse a uid since they are no longer
ambiguous. 

The reason for not deleting users from the users table is so that the
stats records can refer to the original record (who was that person
named "mike"). This is very handy and worth the additional effort it
has taken.

There is no way to ressurect a user, but it would not be hard to add.

sitevariables.

user is a local user. Instead, all users have to send along their keys
in the RedeemTicket() call, and those keys land in the new Emulab
table called nonlocal_user_pubkeys, and tmcd will use that table when
sending keys over local nodes.

This change removes the inconsistency in key handling between slivers
created locally and slivers created at a foreign CM.

(including an update to make schemacheck happy), and client-side script
modifications.

Tested by me on a few different machines. Ok by Mike.

the tb-set-node-os command with a second optional argument; if that is
present, the first arg is the child OS and the second is the parent OS.
We add some new features in ptopgen (OS-parentOSname-childOSname) based
off a new table that maps which child OSes can run on which parents, and
the right desires get added to match.  We setup the reloads in os_setup
along with the parents.  Also needed a new opmode, RELOAD-PCVM, to handle
all this.

For now, users only have to specify that their images can run on pcvms, a
special hack for which type the images can run on.  This makes sense in
general since there is no point conditionalizing childOS loading on
hardware type at the moment, but rather on parentOS.  Hopefully this stuff
wiill mostly work on shared nodes too, although we'll have to be more
aggressive on the client side garbage collecting old frisbee'd images for
long-lived shared hosts.

I only made these changes in libvtop, so assign_wrapper folks are left in
the dark.

Currently, the client side supports frisbee.  Only in openvz for now, and
this probably breaks libvnode_xen.pm.  Also in here are some openvz
improvements, like ability to sniff out which network is the public
control net, and which is the fake virtual control net.

* 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.

'tables', 'reset', and 'synctables' commands. Rather than assuming all
VLANs live on the One True Experimental Net Stack (unless -S was given),
they all now check the database to see which stack they should be operating
on.

Changed how stack information is currently stored in the database. The
LAN attribute formerly known as 'stack' is now called 'class', and has
two valid values, 'Experimental' and 'Control'. The idea is to record
whether something is an experimental net or control net LAN, not which
specific stack it's on. The 'stack' column in the VLANs table now
records the actual stack_id on which the VLAN has been created.

This is all in support of testbeds that have multiple experimental-net
stacks, as Utah currently does.

can tell ahead of time of experiment has virtnodes.

between experiments and projects using VMs (jail, vservers, openvz,
etc).

* Add new slot to virt_nodes called "sharing_mode". Only admins can set
  this, via the NS file, to create an experiment consisting of nodes
  that are shared. A text string, in case we want to support different
  kinds of sharing modes.

* Add new slot to reserved called "sharing_mode". This is copied from
  the virt_nodes table as above. Also, virtnodes that are currently
  allocated to a shared node, get this slot set, so that the rest of
  the system knows.

* Add a toklen to the "erole" slot of the reserved table, called
  "sharedhost"; erole is returned to the client when it boots, and
  this is how the client knows it is acting as a shared host. We could
  probably compute this value in tmcd, but I did not want to change
  that now.

* Add new slot to interfaces called "trunk". This is set when an
  interface should be set to trunking by "snmpit -t". We previously
  used the vinterfaces table to determine this, but there are other
  cases when we want an interface to be trunked.

  Aside: there is a problem with this approach I realized later;
  trunked interfaces are essentially shared resources of multiple
  vlans, which does not play well with the vlan optimizations in
  swapmod.

* Add new slot to vinterfaces called "bandwidth"; this is the amount
  of bandwidth that link is defined to use (via the NS file). This is
  used in resource scheduling of link bandwidth.

* Add new slot to interface_state called "remaining_bandwidth". For a
  shared node, we have to reserve both the nodes and the link bandwidth.
  We use this slot (with locking) from the mapper_wrapper to make sure that
  the link has not been consumed already by another assignment running at
  the same time.

* Add new tokens "veth-ne", "veth-en", and "vlans" to the osfeatures slot
  of the os_info table. veth-en (encap) and veth-ne (no-encap) are intended
  to replace the current "veths" feature. "vlans" is set for OSs that
  support vlan devices.

* Fix the primary key on the linkdelays table; it needed to have the
  exptidx in the key so that we can allocated linkdelays for different
  experiments to the same node.

to numbered update scripts. To install updates:

	boss> cd /your/srcdir/sql/updates
	boss> perl /your/objdir/db/dbupdate tbdb

For developers, please look in the sql/updates/4/1 file for an example
of how to do updates. For each revision in database-create.sql, create
a corresponding script and add it to the repository. The scripts will
be applied in numeric order (see db/dbupdate.in), starting with the
version recorded in the version_info table. This table is updated by
dbupdate as it runs each script.

alter the way things behave (like the web interface) when
operating on an experiment that is the container for a slice.

in the protogeni code. We no longer save the unencrypted certs after
they are revoked, since protogeni will ignore them. I redid the the
DB table as well, adding a revoked stamp, and the DN so that we can
generate the CRL list from the DB directly, without having to run them
all through openssl.

This commit requires all certs to be regenerated, and the ssl xmlrpc
server to be restarted.
