``announce_to_all_trackers`` controls how multi tracker torrents are

announced to in parallel. If all trackers in tier 0 fails, all trackers

in tier 1 are announced as well. This is the uTorrent behavior. If it's

specification. It defaults to false, which is the same behavior previous

versions of libtorrent has had as well.
