Deadwood snapshot update

I have changed the sqa_bigpacket test to no longer need BIND; it now uses the code I worked on this weekend to do the test. This will allow me to run a version of the test that adds pauses to the TCP transmission, allowing me to test TCP buffering.

As an aside, the code I have been working on this weekend doesn't work when compiled with -O3; since this is a SQA test, I will not resolve this issue but simple compile the code without any optimization.

All SQA tests work, and the code can be looked at by going to maradns.org/deadwood/snap
