The purpose of the tcp_advance_send_head & friends was/is to abstract
the write queue from the TCP worker code. RB-tree wq can then be put in 
place more easily (and I'm hopefully coming to that soon). There are some 
other similar functions in tcp.h as well which currently have only a 
single caller. Please don't undo that work while DaveM is away for a short 
while :-).

IMHO it was a mistake from my side to add frto code into the wq abstaction 
function in the first place though I could use the bogus call that 
tcp_mtu_probe used to make there as an excuse :-), the TCP worker code is 
much better place for it (and it does similar stuff already)...
