The library provides Prometheus metrics
types, collector and exposion formatter.
The library isn't thread-safe for now.
The next first pull request will support
that. Can be use exposion formatted

We must register all listening sockets under one file descriptor
array when calling dns_dispatcher_register() which then calls
net_socket_service_register(). The socket services expects all
the registered sockets under one service context to be in one
array. If this is not done, the latest socket array wins and
the earlier registrations are forgotten.

As the DNS might listen to multicast addresses (like in mDNS) in
different network interfaces, make sure to check the network
interface index when registering the dispatcher context. This
allows two mDNS registrations to more than one network interface.

System lists are not thread safe, therefore all accesses should be
protected with a mutex. Introduce a LwM2M context specific mutex,
and use it whenever lists defined per-context are acessed.

The LwM2M message allocation was not thread safe, i. e. the message was
acquired by setting the ctx pointer, and it was freed by clearing the
entire message structure.
If preemptive threads were enabled, and memset() clearing the message
content was preempted, the message structure being currently zeroed
migh've been allocated and initialized by some other thread. If the
thread releasing the message resumed work, it would continue clearing
the freshly allocated and initialized message structure.
In order to prevent this, introduce a new global mutex for the lwm2m
engine global variables. The mutex is used when LwM2M message is
allocated/deallocated. This will prevent reallocating the message
during the release process.

CONFIG_ZVFS_POLL_MAX is now used to control the maximum number of poll()
entires. Thereby, CONFIG_NET_SOCKETS_POLL_MAX is redundant and shall
be deprecated.
Modify the defaults for NET_SOCKETS_POLL_MAX and ZVS_POLL_MAX so that
the deprecation actually makes sense instead of symbol removal. In case
the application still sets the old config, it will modify the
ZVS_POLL_MAX default.

Move the implementation of zsock_select() to zvfs_select(). This
allows other types of file descriptors to also make use of
select() functionality even when the network subsystem is not
enabled.
Additionally, it partially removes a dependency cycle between
posix and networking by moving functionality into a mutual
dependency.

IPv6 MLD API was so far defined in an internal header. This does not
seem correct though, as application code should be able to join/leave
multicast groups, hence the API should be exposed in a public header,
just as it is done for its IPv4 countepart - IGMP.

The code properly checks that we do not overwrite the destination
buffer even if we use the source buffer length to determine how much
to copy. One possible fix is to use memcpy() or strcpy(), I opted
to use memcpy() because it has the length option which feels more
natural.

The http_client_req() function's timeout parameter is allowed
to be SYS_FOREVER_MS. However, K_MSEC() does not convert this
to a proper k_timeout_t, so sys_timepoint_calc() ends up
returning 0, which is causes immediate timeouts.
Check for this case specifically and force value passed to
sys_timepoint_calc() to be correct.

This commit makes sure we continue to wait for extra confirmations even
after the request is done so we can handle duplicate confirmations if any.
Detailed description:
rfc7252#section-4.5 specifies that:
"The recipient SHOULD acknowledge each duplicate copy of a
Confirmable message".
So if, for example, the client sends to a multicast destination address,
the server will get multiple requests and will confirm all of them.
Without this commit, the client will set the request to done after
receiving the first answer.
From here the request object will be marked as free and the duplicate
acknowledgements will stay buffered in the network stack.
Once the client tries to send a new request, it will unbuffer those
duplicate acknowledgements but now the request object is unallocated
so the client won't be able to handle those acknowledgements as duplicates.
It will instead treat it as an unexpected ACK.
To work around this issue, rfc7252#section-4.8.2 states that:
"EXCHANGE_LIFETIME is the time from starting to send a Confirmable
message to the time when an acknowledgement is no longer expected,
i.e., message-layer information about the message exchange can be
purged."
Keeping the request object allocated for EXCHANGE_LIFETIME ensures that
duplicate acknowledgements can be handled accordingly.
This commit adds a basic implementation of what is stated in the RFC.
EXCHANGE_LIFETIME has been arbitrarily set to 3 * ACK_TIMEOUT which
seems more reasonable than the 247 seconds stated in the RFC.

In this scenario, the `break` statement is the more suitable choice.
