Merge the newstated branch with the main tree.
Changes to watch out for: - db calls that change boot info in nodes table are now calls to os_select - whenever you want to change a node's pxe boot info, or def or next boot osids or paths, use os_select. - when you need to wait for a node to reach some point in the boot process (like ISUP), check the state in the database using the lib calls - Proxydhcp now sends a BOOTING state for each node that it talks to. - OSs that don't send ISUP will have one generated for them by stated either when they ping (if they support ping) or immediately after they get to BOOTING. - States now have timeouts. Actions aren't currently carried out, but they will be soon. If you notice problems here, let me know... we're still tuning it. (Before all timeouts were set to "none" in the db) One temporary change: - While I make our new free node manager daemon (freed), all nodes are forced into reloading when they're nfreed and the calls to reset the os are disabled (that will move into freed).
