Randall Stewart e022f2b013 tcp: Rack fixes and misc updates 
So over the past few weeks we have found several bugs and updated hybrid pacing to have
more data in the low-level logging. We have also moved more of the BBlogs to "verbose" mode
so that we don't generate a lot of the debug data unless you put verbose/debug on.
There were a couple of notable bugs, one being the incorrect passing of percentage
for reduction to timely and the other the incorrect use of 20% timely Beta instead of
80%. This also expands a simply idea to be able to pace a cwnd (fillcw) as an alternate
pacing mechanism combining that with timely reduction/increase.
