After introduction of struct http_response_ctx, the dynamic resource

Add tests covering new method of providing a response for dynamic
resources.
Tests cover the application sending response codes and headers,
overriding "default" headers, and sending various combinations of
headers and body data. Each case is tested for HTTP1 & HTTP2, both POST
and GET methods.

This also allows simple requests to be completed in a single execution

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.

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
TLS handshake, the TLS socket may block indefinitely during
connect()/accept(), waiting for data from the peer. This should be
avoided, hence use the preconfigured timeout for the TLS handshake,
same as we use for TCP-level handshake.

If the dispatcher is muxing the connection i.e., so there are two
services for the same port, then mark service socket descriptor

command can show a proper value for it.
Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
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.

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.

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.

Using strncasecmp to match HTTP headers can give unexpected results when
the strings to be compared match up until the end of one string, but the
other string contains additional characters. This can result in falsely
matching a HTTP header value, for example:
strncasecmp("Upgrade-Something", "Upgrade", sizeof("Upgrade") - 1) --> 0
In this case we know that both strings are NULL terminated since one is
a string literal and we have just length-checked and explicitly NULL
terminated the other. So we can just use strcasecmp without a max
length.
