tcp: expose the tcp_mark_push() and tcp_skb_entail() helpers
[ Upstream commit 04d8825c30b718781197c8f07b1915a11bfb8685 ]
the tcp_skb_entail() helper is actually skb_entail(), renamed
to provide proper scope.
The two helper will be used by the next patch.
RFC -> v1:
- rename skb_entail to tcp_skb_entail (Eric)
