Move tcp_try_coalesce() protocol independent part to skb_try_coalesce(). skb_try_coalesce() can be used in IPv4 defrag and IPv6 reassembly, to build optimized skbs (less sk_buff, and possibly less 'headers') skb_try_coalesce() is zero copy, unless the copy can fit in destination header (its a rare case) kfree_skb_partial() is also moved to net/core/skbuff.c and exported, because IPv6 will need it in patch (ipv6: use skb coalescing in reassembly).
