rtorrent-0.9.8-v6.0

Version 6.0 Release

This release includes a rewrite of the UDNS interface for libtorrent to increase performance and stability of UDP trackers. It can be enabled by configuring libtorrent with --enable-udns. It is now more stable than rakshasa's resolver interface.

1. The resolver callbacks are now handled by the connection manager to avoid a crash when the UDP tracker becomes invalid.
2. The UDP trackers are now optimized with a fast-path to IPV4, since the UDNS interface can only support one DNS resolution method a time. This significantly reduces the amount of CPU instructions required to update a UDP tracker and avoids redundant network sockets.
