a further CPU enhancements for compressed acks. These are acks that are compressed into an mbuf. The transport has to be aware of how to process these, and an upcoming update to rack will do so. You need the rack changes to actually test and validate these since if the transport does not support mbuf compression, then the old code paths stay in place. We do in this commit take out the concept of logging if you don't have a lock (which was quite dangerous and was only for some early debugging but has been left in the code).
