New Deadwood snapshot

In today's snapshot, dwc_decompress() now returns RRs in the format I want to return them in (offsets for the beginning of RRs to make RR rotation easier; offsets of the beginning of TYPE in RRs to make TTL aging easier; followed by AN/NS/AR counts and one-byte type). I'm also starting work on getting all functions to be 52 lines or less again to keep the code readable.
