migrate to new server

[warner]

This ticket is to track the task of moving this Trac instance, and the mailing lists, etc, from the old original "org" box (currently in the Undisclosed Location) to the new linode-based "new-org" box.

Remaining Tasks:

• get basic webserver running
• move Mailman, list archives, cgi-bin/mailman control panels
• update MX records to send tahoe-lafs.org mail to new box
• copy all trac DBs/workdirs to new box
• activate all trac instances on new box
• copy all static content (tarballs, deps, debs, all sorts of random stuff)
• move source trees, canonical darcs repos
• get post-commit hooks working
• get any cronjobs migrated
• move buildmaster, either get buildslave admins to update their configs, or wait for DNS to change
  • add "buildmaster.tahoe-lafs.org" DNS name (pointing at new-org)
  • tell buildslave admins to point buildslaves at that
  • meanwhile, old slaves will just use tahoe-lafs.org and work normally
• update DNS
• power down old box, or move to Peter's basement for emergency access
• set up trac backup-to-git cronjob on new box
• get SSL cert fixed
• fix bitcoin-donation box on front page
• repopulate ​http://tahoe-lafs.org/source/tahoe-lafs/deps/tahoe-dep-sdists/
• check other tahoe-deps directories
• move the external (non-https) hosted images from the front page to the local server, to hush the mixed-content warning

I've started the rsync of /home/source/darcs/tahoe-lafs (1.7GB in 33 trees). The target is /home/warner/incoming
