UDP packets sent in response to a UDP request should have the same
source address as the request's destination address.
This can be achieved with sockets bound to a specific address, but in
the case of ANY-bound sockets, we can use the PKTINFO mechanism to do
this.
Extend control_ng_process() to accept an extra socket address
corresponding to the local address to use. Extend the signature of the
callback function (to do the actual sending) accordingly.
Extend socket_sendiov() to be able to set the PKTINFO cmsg when sending
a packet.
Add socket_sendto_from() as a convenience wrapper.
Extend control_udp_incoming() to pass the address from
udp_buf->local_addr back to socket_sendiov().

Introduce `media_unconfirm()` to do a selective handling

Previous implementation assumes that we use the `call_subscription`
objects in:
- `call_offer_answer_ng()`
- `call_update_lookup_udp()`
- `call_request_lookup_tcp()`
when appealing to the `call_get_mono_dialogue()`, in order to
get the `call_subscription` objects, in order to then pass it
for usage in the `monologue_offer_answer()`, where the most important
again is to use monologue references stored inside
the given `call_subscription` objects.
Instead of using the `call_subscription`, just use `call_monologue`
objects as a base data objects for this work,
which will allow us in the coming commits to deprecate
the `call_subscriptions` based model and
get to the subscription model based on medias.

Transcoding is flow-specific, so it doesn't make sense to have a flag

subscribers) have transcoding enabled.

Due to multiple threads polling all sockets for read events, it's
possible for one socket to receive a read event in one thread, then
immediately receive another read event in another thread, resulting in
two threads reading packets from the same socket at the same time.
While this is perfectly valid and correctly handled by mutex etc, it can
result in packets being processed out of order. In media passthrough
scenarios which don't do sequencing this can result in packets being
reordered.
Using a simple atomic counter we can ensure that only one thread is
reading from any one socket at a time.

`stats_counters_calc_diff` is used to calculate stats as differences

This is a new option flag, which provides a possiblity
to select specific crypto suite(s) for the offerer from
the given list of crypto suites received in the offer.
This will be used later on, when processing an answer from

Furthermore, this is being decided not when the answer is processed,
but already when the offer is processed.

This is a new option flag, which provides the ordered list,
in which to add crypto suites into the SDP body.
Right now they're always added in the order given in the source code.
Flag usage example:
`SDES-order:AES_256_CM_HMAC_SHA;AES_256_CM_HMAC_SHA1_32;AES_192_CM_HMAC_SHA1_80;`
This means — those listed SDES crypto suites will be added
into the generated SDP body at the top of crypto suites list, in the given order.
But, each of them is added, only if it is about to be added/generated.
In other words, the `SDES-order:` flag itself doesn't add crypto suites,
it just affects the order of those suites to be added.
And the rest of non-mentioned suites, which are also to be added,
will be appended after those given, in the free manner of ordering.
Important thing to remember - it doesn't change the crypto suite tag
for the recipient, even though changing the order of them.
Additionally.
This flag does not contradict with `SDES-nonew`, `SDES-only-` and `SDES-no-` flags.
It just orders the list of crypto suites already prepared to be sent out.

Add a new flag to only accept these individual crypto suites
and none of the others.
For example, `SDES-only-NULL_HMAC_SHA1_32`
would only accept the crypto suite `NULL_HMAC_SHA1_32` for
the offer being generated.
This also takes precedence over the `SDES-no-` flag(s),
if used together, so the `SDES-no` will be not taken into account.
This has two effects:
- if a given crypto suite was present in a received offer,
it will be kept, so will be present in the outgoing offer; and
- if a given crypto suite was not present in the received offer,
it will be added to it. The rest, which is not mentioned,
will be dropped/not added.
Flag name: 'SDES-only-<crypto name>'

Use the new `associated_tags` table to determine which tags are
associated with which. Iterate the associations between tags in a
tree-like manner and do this at the moment the `delete` command is
received. Break up the `associated_tags` links at this time, and
determine which tags would be left dangling and mark all of these for
deletion. If no tags are left after this process, mark the entire call
for deletion.
The previous approach was cumbersome and prone to errors. Using tag
names and branch names to determine which tags are associated with which
is a pointless hurdle, and using a table of associations that is
explicitly kept for this purpose is a much cleaner approach. Also
postponing the decision about which tags to delete until the time the
deletion actually happens can lead to tags not being deleted, when they
really should be (e.g. A -> B, delete A, A -> C).

Keep track which tags (monologues) were created together as part of an
offer/answer exchange with a separate hash table, regardless of whether
these monologues actually have tagged names or are just nameless
branches.

In some cases it's possible that some packets still arrive in userspace
immediately after a stream has been pushed to the kernel, for example if
some packets are already in the queue or if there is some processing
delay (e.g. writing to Redis). Allow for a short delay before counting a
stream as userspace if it has been pushed to the kernel.

On bookworm and later, libasan reports a false positive in combination
with pthread_cleanup_push() (see [1]). Work around this by not using the
thread cleanup handler when running the asan build, and instead use a
shorter thread sleep time.

Instead of just leaving the transport protocol unset when we know we're

Add TLS ALPN option to be set when connecting MQTT
This is required to be set to "mqtt" for instance when connecting
to the AWS IoT Core data endpoint at port 443 to indicate we're
sending MQTT, because in that case websocket and mqtt shares the same
port for whatever reason.

Newer libwebsockets versions seem to use a longer internal timeout, so
an explicit "interrupt" is needed during shutdown to prevent a long wait

To prevent a race condition that might miss updates about call info, set
up the Redis keyspace notifications first and then run loop to restore
calls from the existing data.

When ports are closed early (while the call is still running), we must
first update a slave rtpengine with this new information (that these
ports are now closed) before actually releasing the ports ourselves. Not
doing so leads to a race condition where the master instance re-uses a
port that was just closed before the slave instance knows about the port
being closed.
We implement this using a thread-local list to keep track of ports that
were released while processing a control message, and process this list
to actually close the ports only after Redis has been updated.
Additional calls to the function to close the ports are placed in
strategic locations to make sure this is triggered in every code path.

There's no need to open ports on non-primary interfaces if ICE is not in
use as these ports will not be used or seen by anyone.
This mostly obsoletes the `save-interface-ports` config option, with the
exception of ICE advertised by the offerer. We currently have no option
to reject ICE from the offerer during the offer phase, so ports would
always be opened on that side.

Special handling for codec lists that were received as part of an
answer: If the list includes a codec that was not offered, ignore that
codec. This prevents transcoders from being set up that were not
requested.
This brought to light some tests that were actually broken.

Handling of dual stack v4/v6 was previously done by the individual
listener objects for INADDR_ANY listening addresses. If listening on
INADDR_ANY was requested, then each listener would create two instances,
one for IPv4 and one for IPv6. This works fine for INADDR_ANY but fails
for listening on host names that resolve to multiple addresses, such as
`localhost`.
Solve this by relieving the listener objects from handling this and
instead handle it in the code setting up the listeners. If a host name
resolves to multiple addresses, then set up multiple listeners (up to
two supported currently). This allows us to listen on `localhost` by
default and have both 127.0.0.1 and ::1 active. INADDR_ANY is handled
specially by also setting up :: in that case.
