Subject: dst: Pass a sk into .local_out

For consistency with the other similar methods in the kernel pass a
struct sock into the dst_ops .local_out method.

Simplifying the socket passing case is needed a prequel to passing a
struct net reference into .local_out.

Subject: ipv4: Merge ip_local_out and ip_local_out_sk

It is confusing and silly hiding a parameter so modify all of
the callers to pass in the appropriate socket or skb->sk if
no socket is known.

Subject: ipv6: Merge __ip6_local_out and __ip6_local_out_sk

Only __ip6_local_out_sk has callers so rename __ip6_local_out_sk
__ip6_local_out and remove the previous __ip6_local_out.

Subject: ipv6: Merge ip6_local_out and ip6_local_out_sk

Stop hidding the sk parameter with an inline helper function and make
all of the callers pass it, so that it is clear what the function is
doing.
