Appropriate enviroment cleaning and taint checking is done, and it drops
root privileges immedeately after opening the logfile, so frisbeed still
runs as the invoking user rather than root.

out for some reason, and added an example of the intended usage.

snmpit_intel module conform to the same API as snmpit_cisco.

Intels VLANs are now done per port rather than per MAC. This should give
experimenters more flexibility on the experimental net, and is more consistent
with the way that VLANs are done on other switches.

snmpit_intel_stack will need to undergo minor work to support stacks of
multiple switches.

* Add appropriate goo to os/GNUMakefile so that Frisbee daemon is
  built and installed.

* Rework the frisbee launcher slightly. Aside from little changes
  (send email to tbops when frisbeed dies, new cmdline syntax to
  frisbeed), allow for frisbeed to exit gracefully after a period of
  inactivity (no client requests for 30 minutes, at present). In order
  to prevent a race condition with a new client being added (and
  rebooted) and frisbeed terminating before the client gets started,
  add a load_busy indicator to the images table (next to load_address
  slot) and set that to one each time to frisbeelauncher is invoked.
  When frisbeed exits, test and clear that bit atomically (lock
  tables) and go around another time (restart frisbeed for another 30
  minute period).

* Rework waitmode in os_load. Wait for all of the nodes to finish at
  once, and track which nodes never finish. Retry those nodes again by
  rebooting. The number of retries is configurable in the script, and
  is currently set to one. This should take care of some PXE boot
  related problems, although obviously not all.

* Got rid of -w option to os_load and made waitmode the default. The
  -s option can be used to start a reload, but not to wait for it to
  complete.

* Minor changes to sched_reload and reload_daemon; pass in -s option
  to os_load.

code had been added in a bunch of places to clear the data out.

The portmap table in the database can now be dropped.

The frisbee launcher now deals with multiple requests.

flood (say, if there were 40 clients wanting chunks). I added some
backoff code that will slow the rate at which the clients make
requests in the face of a non asnwering daemon. Backs off in
increments of the PKTRCV timeout value (30ms at present), until it
gets to one second. Then it holds at one second intervals.

status when we kill them off intentionally.

defs file. For mini, revert the domain back to .emulab.net and set the
suffix to "-mini". For the others, default it to "" to avoid
invalidating current users and logins. Tested with opera, and seems to
work okay now.

Capserver and capture now handshake the owner/group of the tipline.
Owner is defaults to root, and the group defaults to root when the
node is not allocated. Capture will do the chmod after the handshake,
so if boss is down when capture starts, the acl/run file will get 0,0,
but will get the proper owner/group later after its able to handshake.
As a result, console_setup.proxy was trimmed down and cleaned up a
bit, since it no longer has to muck with some of this stuff.

A second change was to support multiple tiplines per node. I have
modified the tiplines table as such:

	| Field   | Type        | Null | Key | Default | Extra |
	+---------+-------------+------+-----+---------+-------+
	| tipname | varchar(32) |      | PRI |         |       |
	| node_id | varchar(10) |      |     |         |       |
	| server  | varchar(64) |      |     |         |       |

That is, the name of the tip device (given to capture) is the unique
key, and there can be multiple tiplines associated with each node.
console_setup now uses the tiplines table to determine what tiplines
need to be reset; used to be just the name of the node_id passed into
console_setup. Conversely, capserver uses the tipname to map back to
the node_id, so that it can get the owner/group from the reserved
table.

I also removed the shark hack from nalloc, nfree, and console_reset,
since there is no longer any need for that; this can be described
completely now with tiplines table entries. If we ever bring the
sharks back, we will need to generate new entries. Hah!
