tcp: refactor struct tcp_skb_cb
Refactor tcp_skb_cb to create two overlaping areas to store state for incoming or outgoing skbs based on comments by Neal Cardwell to tcp_nv patch: AFAICT this patch would not require an increase in the size of sk_buff cb[] if it were to take advantage of the fact that the tcp_skb_cb header.h4 and header.h6 fields are only used in the packet reception code path, and this in_flight field is only used on the transmit side.
