Deadwood snapshot update

Since I have a real AFK (away from keyboard) life this week, Deadwood progress will be slow until I become an über-geek again. In the meantime, I have started work on the DNS compression code. I'm doing a bottom-up approach (with the decomression code, I started with then bottom-up approach, switched to a top-down approach, and finished up the code by meeting in the middle).

I'll probably have DNS compression finished up next week sometime. After that, it's time to work on RR rotation and TTL aging.
