Small changes to image access permissions checks. Root can get any image it wants, and frisbeelauncher only requires READINFO permissions, so that users can os_load shared images still. Also, have os_load pass its debug flag to frisbeelauncher if set.

-r. When this check is made, frisbeelauncher is still running as root,
and -R uses the real, rather than effective, uid for the check.

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.

* 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.

not start properly, but nothing would complain.

the database.

Manages the launching of new frisbee servers, and recording the
addresses the use in the database. If called for an image that is
already associated with a running server, exits quitely. Otherwise,
registers the new server's address and goes into the background, waiting
for the frisbee server to die so that it can unregister the address.
