When the context being used is bound to a multicast address, the source
address of the IPv6 packet was the multicast address, this is wrong. See
RFC4291, Section 2.7:
"Multicast addresses must not be used as source addresses in IPv6
packets or appear in any Routing header."
If the context was bound to an address that would be invalid as an IPv6
source, we find a better alternative.

We were dropping the packet too early as the neighbor cache might
have the peer address stored so the cache needs to be checked too.

When we receive IPv6 neighbor solicitation message,
we must not re-use the RX buffer when sending the IPv6
neighbor advertisement. This was an issue for IEEE 802.15.4
technology which has a variable size link layer header.
If we use the RX buffer for sending, the size of the link
layer header can be wrong and the packet might be dropped
by the L2 layer.

15.4 drivers are supposed to append LQI byte in the end of the buffer,
but of course there is no such thing in uart-pipe. Thus the bug, so
let's announce the proper length even if such LQI is missing.
Also align the debug output to proper length (FCS included)

Parse and validate the sequence number and send the ACK synchronously
in the tcp_established() callback. No attempt is made to unify the
packet with any queued data (which isn't queued yet, but might be
someday).
Note that this requires that an accepted context clone over the
sequence numbers from the listening context (which received them
during the SYN).
(Note also that this exposes a bug in the current SYN handling:
there's only space for one set of sequence numbers on that listening
context, so if we get two SYNs before the round trip ACK arrives we'll
"accept" the wrong connection with garbage sequence numbers and both
connections will fail).

My previous race cleanup missed the fact that the memset would end up
clearing the IN_USE flag! So we were always allocating the same
struct net_tcp (which, because the typical use is to listen on one
socket and then transfer on an accepted socket, almost kinda worked
for a lot of stuff, making this hard to find).
