Log Message:	Add support for DragonFly BSD. Seems to be working correctly, and works without needing any extra privileges. Some stuff comes from proc.h, whilst some comes from thread.h. A word of warning - the DragonFly folk seem to be changing a lot of stuff to do with processes and threads, so it's likely this could break very easily :-)
