d3efcbd316 net: prometheus: Remove need to have separate metric struct
Embed "struct prometheus_metric" to individual metric like
counter, gauge, histogram and summary. This way we avoid having
a separate base pointer in specific metrict struct. We also do
not need to search the specific metric from base metric as
we can simply use CONTAINER_OF() macro to get the base metric.

This embedding means that the counter, gauge, histogram and summary
metric define macros are changed as user does not need to create a
separate "struct prometheus_metric".

Convert the tests and sample to use the new macros.

Remove also the static from metric creation macros so that user
can decide whether it needs collector to be static or not.

72534b83e4 net: lib: sntp_simple: Handle responses from previous iterations
SNTP simple runs request iterations with exponential backoff.
If the net interface is a slower connection (ie. CAT M1 modems)
then the request will be sent but the response may take time to
be received, thus causing a timeout and another request to be sent.
Because of the nature of UDP and the fact that the same socket
(source IP/port combo) is being used for both requests, a delayed
response to the first request can be received as the response to the
second request, causing -EINVAL to be returned when the timestamps
mismatch (see subsys/net/lib/sntp/sntp.c). The solution provided
retries receiving the response when the timestamp is mismatched
(without sending an additional request).

b8751c669b net: lwm2m: Make LwM2M message allocation thread safe
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.

The code properly checks that we do not overwrite the destination

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.

bfed8d0966 net: lib: coap_client: wait for all acknowledgements
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.

af4527e131 style: subsys: adjust return usage in void functions
For code clarity, this commit adjusts the use of `return` statements
in functions with a void return type as follows:
- Transform `return foo();` into separate statements:
  `foo();`
  `return;`
- Remove unnecessary `return` statements when
  they don't affect control flow.

44ba8a5485 net: dhcpv6: adjust switch-case in dhcpv6_enter_state
For code clarity, unified switch-case usage in `dhcpv6_enter_state` to
use `break` instead of `return`.
Typically, a `break` is used in switch-case statements unless an early
return is necessary, in which case `return` is appropriate.

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

In case peer goes down or we disconnect from the network during the

caf9fd345f net: dns: Add per socket user data for the dispatcher
The socket services API has a limitation where the user data is shared
between file descriptors described in the same service.

This can cause problem in DNS dispatcher where each listened socket
needs to have their own dispatcher struct set as user data so that we
can map between dispatcher context and socket. Solve this by always
have a dispatcher table as user data, and then have the actual mapping
done via the dispatcher table when receiving data to the dispatcher socket.

dcb71a754f net: http_server: Enable v4-to-v6 mapping by default
Fixing the regression caused by 3949873886 ("Allow service to be
created with NULL host"). If the host parameter is null when creating
the HTTP service, the IPv6 socket is created by default. This can cause
issues if both IPv4 and IPv6 are enabled, like in HTTP server sample,
and the HTTP client connection is done by IPv4.
To fix this, we need to enable IPv4-to-IPv6 mapping in order to allow
IPv6 socket to serve a IPv4 connection. Allow also user to override this
if needed.

e6f942f238 net: lwm2m: Fix enabler version reporting during bootstrap discovery
LwM2M 1.1 specification mentions that the enabler version format was
specified wrongly in LwM2M 1.0 specification, and servers only "may"
accept the old format, which no longer seems to be the case for Leshan.

The URI reference ("</>;") before the enabler version is now mandatory,
if it's missing the bootstrap discovery fails with Leshan. Another
problem are quotes around the enabler version, which seems to be
conditionally accepted only for LwM2M version 1.0. Therefore, keep the
quotes only for that version, to prevent any potential issues with other
servers.
