The IEEE 802.1Q chapter I.3 contains a proper network packet
priority to traffic class mapping. The original mapping was
clearly incorrect.

With fragmentation disabled echo server responds to packet fragment with
ICMPv6 message Type: "Parameter Problem (4)", Code: "unrecognized Next
Header type encountered (1)". If a fragment with payload length 15 is
received in response sent by echo server IPv6 payload length and ICMPv6
checksum are wrong. This patch solves the issue by correcting payload
length.

This commit fixes crash caused by double free from message sequence
fragmentation. When double free happens the call stack is:
0 reassembly_cancel
1 handle_fragment_hdr
2 net_ipv6_process_pkt
3 process_data
4 processing_data
5 net_rx
6 process_rx_packet
7 work_q_main
8 _thread_entry
So at first packet is unrefed in reassembly_cancel and then also in
processing_data.

After successful send, the packet is automatically cleared, so
trying to call print_send_info() on it leads to errors:
[net/pkt] [ERR] net_pkt_tcp_data: NULL fragment data!
[net/tcp] [ERR] net_tcp_get_hdr: NULL TCP header!
(if error logging enabled).
This change is similar to how print_send_info() is called in
existing send_reset() function of this source file.

If we have multiple network interfaces and we want to send
a IPv4 network packet to certain destination, then this new
helper can be used to figure out what network interface to use.
Note that this commit only adds support to select the correct network
interface according to destination IPv4 address. This does not enable
any automatic routing to happen.

Exposing connect, disconnect and scan for now.
In case the iface is an instance of a WiFi offload device, the way it
manages scanning, connecting and disconnecting will be specific to that
device (not the mgmt interface obviously). In such case the device will
have to export relevantly a dedicated bunch of function to serve the
mgmt interface in a generic way.

According to RFC 793 we should wait for FIN in FIN_WAIT_1 and
FIN_WAIT_2 states. Receiving ACK in FIN_WAIT_1 just moves us to
FIN_WAIT_2 state.
Right now TCP connection is never closed if FIN is not received
in FIN_WAIT_2 state. Fix that by keeping fin_timer active in
FIN_WAIT_2 state, but canceling it just after FIN is received.

- There is a mismatch when interfacing with external code where a
uint32_t is defined as a parameter and internal Zephyr code attempts
to use u32_t. If NewLib is used, the typedef for u32_t is
'unsigned int' which is not a portable match to uint32_t as
'unsigned int' is not a common size across architectures so gcc will
output a warning.
- The mcux flash code calls NXP supplied functions that expect a
uint32_t.
- openthread.c ot_state_changed_handler has a uint32_t flag as a
parameter.
