Log Message:
Merge changes in the trickle-sync and softdep code as done by Kirk McKusick
in FreeBSD since the version that we based the branch on. Merging mostly
done by Ethan Solomita <ethan%geocast.com@localhost>.

Also, make sure the syncer thread/process isn't active when we're
unmounting a filesystem. This could wreak havoc. XXX should be done
on a per-mountpoint basis, but especially the softdep code would
end up to be a big pile of vfs_busy() calls.
