Web browsers don't support HTTP Upgrade mechanism to upgrade to HTTP2.
Instead, HTTP2 is supported only over TLS, and ALPN is used to negotiate
the protocol to be used.
This commit adds the supported HTTP protocols to the ALPN list, so that
web browsers can use HTTP2 with the server.

Fixes: #78010
This commit implements the "Gateway Advertisement and Discovery" process
defined in section 6.1 of the MQTT-SN specification.
This includes breaking changes to the transport interface and the default
included UDP interface implementation as support for UDP multicast
messages is added as implemented by the Paho MQTT-SN Gateway.

If network interface is specified in the DNS server, then send
the queries to the server via the network interface. Print this
information in the server list.
Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
Allow user to specify a network interface in the DNS server
list. User can append "%" and network interface name to the
DNS server to use this. If the network interface is mentioned
in the server list, then the DNS queries are sent via this network
interface.
For example setting the interfaces like this:
192.0.2.2%eth1
[2001:db8::2]:5353%ppp0
would cause the DNS queries to sent to 192.0.2.1 via eth1 in the first
example, and to 2001:db8::2 via ppp0 in the second example.

When response is received and handled, don't just clear the structure
but instead mark it as ongoing=false.
So if we later on receive a duplicate response for it, we can still
respond with Ack or Rst.
This is achieved by using release_internal_request() when we don't
expect any response for it and reset_internal_request() when we really
fill up a new request.

The sock_obj_core_dealloc() was not called if close() is called
instead of zsock_close(). This happens if POSIX API is enabled.
Fix this by calling zvfs_close() from zsock_close() and then
pass the socket number to zsock_close_ctx() so that the cleanup
can be done properly.

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).

In receiving thread, continuing the loops is based on
has_ongoing_exchanges() so it does not need atomic
coap_client_recv_active variable.
When idling, it wakes from semaphore. But there was potential
deadlock when coap_client_schedule_poll() would not signal the
semaphore, if atomic variable was already showing that it runs.
Removing the atomic variable removes this deadlock.

It is error prone to flag separate booleans, so try to use

If send() fails, we have not technically send the CoAP retry yet, so
restore the same pending structure, so our timeouts and retry counters
stay the same.
This will trigger a retry next time the poll() return POLLOUT, so we
know that we can send.

Refactor the CoAP retry handling into the handle_poll() function,
so that we only try to send retries if the socket reports POLLOUT.
Also move the receiving into same loop, so when poll() reports POLLIN
we recv() the message and handle it before proceeding to other sockets.
Also fix tests to handle POLLOUT flag and add support for testing
multiple clients.

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.
