The send_queue was used as SYN/FIN packet retransmission. Before
the SYN/FIN being ACKed and dequeue-ed, the following packets in
the send_queue cannot be sent out. That's why Zephyr had to send
a FIN+ACK instead of a duplicated ACK-only in FINWAIT1, CLOSING.
In fact, we can take SYN/FIN as kind of data and use the same
send_data_timer for retransmission, like other OSes do. This way,
the send_queue is simply used for local traffics.
Benefits (in theory):
1. The code is easier,
2. TxPkt performance is better after skipping enq/deq send_queue,
3. The struct tcp{} node is a few bytes smaller, saving memory.

"udp bind" and "udp send" commands use the same net context
variable and they fail early if the context is already used.
This prevents from using "udp send" after "udp bind", which
makes the commands hard to use for testing bidirectional
communication. Make "udp send" reuse the already bound
context if possible, and resort to allocating temporary one
otherwise.

The _ is a reserved character in front of the symbols so remove
it from network management event macros. The remaining string
without the _ will identify the network API anyway so having
underscore there is not needed.

Add a "net filter" command that will allow user to see the
current network packet filter configuration.
Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
As the network packet filter drops packets without any indication
that the packet is dropped, it can be difficult to monitor what
is going on in the system when receiving data. The user can
now monitor the statistics and see if packets are being dropped
because of packet filter activity.

Previously the net_linkaddr struct had pointers to the link address.
This is error prone and difficult to handle if cloning the packet as
those pointers can point to wrong place. Mitigate this issue by
allocating the space for link address in net_linkaddr struct. This will
increase the size of the net_pkt by 4 octets for IEEE 802.15.4 where the
link address length is 8, but there no increase in size if link address
is 6 bytes like in Ethernet/Wi-Fi.

If VLAN count is set to 0, then only priority tagged VLAN frames
that have tag value 0 can be received. Also this means that VLAN
interfaces are not created which can save memory if you do not need
to receive any other VLAN frames than those tagged with value 0.

IPv6 MLD API was so far defined in an internal header. This does not
