[unstable] rtorrent-0.9.8-v5.4

Unstable: Reason UDNS crashes.

Version 5.4 Release

This release includes two hash threads instead of one to better split the load between multiple threads. For instance, instead of 30% on a single thread it will execute two threads with 15%. Half the downloads are assigned to one thread and the other half to the other thread.

UDNS now works as intended. A build issue is fixed for debugging. A handshake build mount is added for later for multi-threading support.
