The "net conn" command printed AF_PACKET socket as AF_UNK(3).
Fix this by printing "AF_PACKET" in this case.

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.

All connection information was printed only if connection debugging
was enabled which then did not print information about Wireguard or
DHCP handlers. Limiting the printouts like this is not really needed
so print all connection information with "net conn" command.

As the common.h is only meant to be used by the network
shell files, rename it to be more descriptive in order to
avoid possible conflicts with any other common.h file.
