Fix two issues with net tcp command:
* The `net tcp` commands are still based on net_context API. For TCP,
the API caller (net shell) should add one extra reference to the
allocated net context, to prevent premature context release in case of
connection teardown. Currently that was not the case, and the context
was released too early, resulting in missing final ACK from the Zephyr
side on connection close.
* The net context API should not be called from the registered connect
callback, as this creates a temporary deadlock situation. The
net_context_connect() function blocks until the connection is
established, or an error or timeout occurs. For that time the
net_context mutex is being locked. In case of connection error (for
example after receiving RST packet) the connect callback is called,
indicating an error. If we try to call net_context API from within, a
deadlock situation takes place, as the context mutex is still locked
by the net_context_connect() (called from the shell thread). This
blocks the further execution of the TCP stack and can result in an
unexpected behavior (like for example retransmitting the SYN packet,
which takes place from yet another thread, TCP work queue).
Fix this, by releasing the net context not from the callback directly,
but based on the return value from net_context_connect().

Replaces the previous approach to define bands via hardware capabilities
by the standard conforming concept of channel pages.
In the short term this allows us to correctly calculate the PHY specific
symbol rate and several parameters that directly depend from the symbol
rate and were previously not being correctly calculated for some of the
drivers whose channel pages could not be represented previously:
* We now support sub-nanosecond precision symbol rates for UWB. Rounding
errors are being minimized by switching from a divide-then-multiply
approach to a multiply-then-divide approach.
* UWB HRP: symbol rate depends on channel page specific preamble symbol
rate which again requires the pulse repetition value to be known
* Several MAC timings are being corrected based on the now correctly
calculated symbol rates, namely aTurnaroundTime, aUnitBackoffPeriod,
aBaseSuperframeDuration.
In the long term, this change unlocks such highly promising functional
areas as UWB ranging and SUN-PHY channel hopping in the SubG area (plus
of course any other PHY specific feature).

Remove the wifi_mgmt interface overriding default values with values
from kconfig. The defaults were only applied when a `params` struct was
provided by the application.
This is the case when the application is explicitly setting the options
it wants, why is the mgmt API changing these. When `params` is NULL and
thus modem defaults are requested, these defaults aren't applied. This
is the opposite behaviour from what seems reasonable.
In addition, these options are:
* Undocumented
* Using non-trivial string parsing functions (strtok)
* Adding complexity to the API implementation by forcing support for
ROM versions of command line arguments.

This commits adds support for the SO_REUSEPORT socket option.
The implementation follows the behavior of BSD and tries to also follow
the specific additional features of linux with the following
limitations:
* SO_REUSEADDR and SO_REUSEPORT are not "the same" for client sockets,
as we do not have a trivial way so identify a socket as "client"
during binding. To get the Linux behavior, one has to use SO_REUSEPORT
with Zephyr
* No prevention of "port hijacking"
* No support for the load balancing stuff for incoming
packets/connections
There is also a new Kconfig option to control this feature, which is
enabled by default if TCP or UDP is enabled.

This commit adds support for the SO_REUSEADDR option to be enabled for
a socket using setsockopt(). With this option, it is possible to bind
multiple sockets to the same local IP address / port combination, when
one of the IP address is unspecified (ANY_ADDR).
The implementation strictly follows the BSD implementation and tries to
follow the Linux implementation as close as possible. However, there is
one limitation: for client sockets, the Linux implementation of
SO_REUSEADDR behaves exactly like the one for SO_REUSEPORT and enables
multiple sockets to have exactly the same specific IP address / port
combination. This behavior is not possible with this implementation, as
there is no trivial way to identify a socket to be a client socket
during the bind() call. For this behavior, one has to use the
SO_REUSEPORT option in Zephyr.
There is also a new Kconfig to control this feature similar to other
socket options: CONFIG_NET_CONTEXT_REUSEADDR. This option is enabled by
default if TCP or UDP are enabled. However, it can still be disabled
explicitly.

There was a corner case which was not handled well in a scenario, when
listening socket was closed during an active handshake with a new
client.
When a listening socket is closed, the accept callback is cleared on the
TCP context. If this happened during a handshake with a new client, i.
e. before final ACK from the client was processed, this lead to a
context leak, as application did not take ownership of the connection
(i. e. had no means to close it).
Fix this, by proactively closing the connection at the TCP level when no
accept_cb is available. Instead of ignoring the fact that no accept_cb
is available, the TCP stack will now enter TCP_FIN_WAIT_1 state and
proceed with a graceful teardown of the connection.

Previously, if a net_context had multiple packets already in

only the content from a single receive buffer would be received.
Since zsock_recvfrom() is a system call, which has a
non-negligible overhead, it makes sense to receive as many bytes
as possible per system call.
Add zsock_recv_stream_immediate() as a shorthand for
"fill this receive buffer with as many bytes as possible without
blocking". Allow nullable buffer parameters so that we can also
have a shorthand for "count how many bytes are immediately
available".

The IEEE 802.15.4 API and networking subsystem were using several
inconsistent timestamp resolutions and types. This change defines all
timestamps with nanosecond resolution and reduces the number of
available types to represent timestamps to two:
* `struct net_ptp_time` for PTP timestamps
* `net_time_t` for all other high resolution timestamps
All timestamps (including PTP timestamps) are now referred to a
"virtual" local network subsystem clock source based on the well-defined
types above. It is the responsibility of network subsystem L2/driver
implementations (notably Ethernet and IEEE 802.15.4 L2 stacks) to ensure
consistency of all timestamps and radio timer values exposed by the
driver API to such a network subsystem uptime reference clock
independent of internal implementation details.
The "virtual" network clock source may be implemented based on arbitrary
hardware peripherals (e.g. a coarse low power RTC counter during sleep
time plus a high resolution/high precision radio timer while receiving
or sending). Such implementation details must be hidden from API
clients, as if the driver used a single high resolution clock source
instead.
For IEEE 802.15.4, whenever timestamps refer to packet send or receive
times, they are measured when the end of the IEEE 802.15.4 SFD (message
timestamp point) is present at the local antenna (reference plane).
Due to its limited range of ~290 years, net_time_t timestamps (and
therefore net_pkt timestamps and times) must not be used to represent

Add new net_if API functions which allow to loop over all valid
IPv4/IPv6 addresses assigned to the interface and execute a callback
function on them.

When parsing user input for "wifi connect" and "wifi ap enable"
commands, the SSID and PSK lengths were not verified. It's better to
detect invalid connect/AP enable parameters early, so that help text can
be printed, instead of letting wifi_mgmt command to fail.
For WIFI_SECURITY_TYPE_SAE, follow the Linux convention of limiting the
size to 128 bytes.

Some DHCPv4 servers do not respect BROADCAST flag set on DHCP Discover,
replying with unicast packet, making it impossible to obtain DHCP
address by Zephyr in such cases.
RFC1542 chapter 3.1.1 makes the following statement about the BROADCAST
flag:
This addition to the protocol is a workaround for old host
implementations. Such implementations SHOULD be modified so
that they may receive unicast BOOTREPLY messages, thus making
use of this workaround unnecessary. In general, the use of
this mechanism is discouraged.
Making it clear that being able to process unicast replies from the DHCP
server is not only an optional behavior, but a recommended solution.
Therefore, introduce a support for unicast DHCPv4 in Zephyr. To achieve
this, add additional filtering rule at the IPv4 level - in case DHCPv4
is enabled, there is an active query and the packet is destined for the
DHCPv4 module, let it through for the DHCPv4 module to process,
regardless of the destination IP address.
