[SK_BUFF]: More skb_reset_transport_header conversions

These are a bit more subtle, they are of this type:

-       skb->h.raw = payload;
        __skb_pull(skb, payload - skb->data);
+       skb_reset_transport_header(skb);

__skb_pull results in:

skb->data = skb->data + payload - skb->data;
skb->data = payload;

So after __skb_pull we have skb->data pointing to payload and we can
just call skb_reset_transport_header(skb), that will do:

skb->h.raw = payload;

The others are similar, allowing us to get rid of some more cases where a
pointer was being attributed to the layer headers.

[NET]: Adding SO_TIMESTAMPNS / SCM_TIMESTAMPNS support

Now that network timestamps use ktime_t infrastructure, we can add a new
SOL_SOCKET sockopt  SO_TIMESTAMPNS.

This command is similar to SO_TIMESTAMP, but permits transmission of
a 'timespec struct' instead of a 'timeval struct' control message.
(nanosecond resolution instead of microsecond)

Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP

A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are
mutually exclusive.

sock_recv_timestamp() became too big to be fully inlined so I added a
__sock_recv_timestamp() helper function.

12 years ago[NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution

[NET]: Introduce SIOCGSTAMPNS ioctl to get timestamps with nanosec resolution

Now network timestamps use ktime_t infrastructure, we can add a new
ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'.
User programs can thus access to nanosecond resolution.

[TCP]: Abstract out all write queue operations.

This allows the write queue implementation to be changed,
for example, to one which allows fast interval searching.
