(cherry picked from commit 5daae51b5b)
If a SSRC object is still in use (refcount is >1), keep it in the list,
even if the list is too large.
Otherwise we may end up recreating a new SSRC object for the same SSRC
that still has an object in use elsewhere, making locks unreliable.

(cherry picked from commit 26fee2610a)
Per RFC 4867 section 8.1, absent fmtp parameters imply defaults (bandwidth-efficient mode, no CRC,
no robust-sorting, no interleaving). Previously, codec matching was rejected when either side had no
``a=fmtp`` attribute for the AMR payload type, causing AMR to be dropped as a "stray answer codec".
This patch changes this behavior to instead "parse" fmtp even when absent so that the format struct
is populated with zero-initialized defaults and fmtp_parsed is set.

To not come across the sink's mutation (e.g. `endpoint.address.family`)
just lock way earlier, before to start processing and
translating endpoint to the kernel related structs.
Otherwise the other signaling path may mutate something
which will make the sink unactual and provide
to the `__re_address_translate_ep()` NULLed or garbage structs.

16de9688d6 resets the `socket.family` to NULL,
that makes the direct appeal to the corresponding
object unsafe.
E.g. `ps->selected_sfd->socket.family->name` when
filling the streams.
Add a simply guard and log `none` in case
the ip family is NULL.

We use `family == NULL` as test for the socket being open in several
places, and expect it to match the familt of the addresses. Set it to
zero to make it consistent.

(cherry picked from commit 16de9688d6)
ICE drops packets early in media_demux_protocols() (via
ice_peer_address_known()), which means in media_packet_address_check()
we can immediately set any socket as confirmed that has received
anything.
Take receiving socket into account to determine whether the endpoint is
a match.
Disable endpoint learning with ICE. ICE is in charge of determining
endpoint address and local socket.
`media-handover` and `strict-source` handling remains in place. With
`media-handover` set, we allow changing endpoint and local socket based
on what is actually received, overriding the nomination from ICE.

Previously, the ports used for a monologue subscription would leak upon re-subscribe.
``__assign_stream_fds`` cleared the stream fd queue without decrementing the ref count. This
prevented ``monologue_destroy`` from releasing the ports on unsubscribe.

(cherry picked from commit e6469c006b)
In case of the reverse direction of a subscription, no stream handler will be found. Previously, the
decrypt struct was left zeroed, the kernel module rejected this with ``EINVAL`` and the daemon logged:
```
[core] Failed to push relay stream to kernel: Invalid argument
```
This patch sets ``REC_NULL``/``REH_NULL`` and marks the target as non-forwarding, matching what is
expected by ``validate_srtp``.

(cherry picked from commit 71cceeed5a)
ffmpeg's CNG expects a fixed frame size, or at least a maximum frame
size, as it allocates internal buffers on construction based on that
frame size. Calling the decoder with a larger frame size therefore leads
to an internal buffer overflow. Calling it with a smaller frame size is
fine.
Retain the simple one-shot CNG for the most common case (frame size
smaller than the max). For larger frames, call the CNG in a loop and
manually construct a return frame.

Currently the helper accepts 0 length, but callers actually
can try to mutate it with `- 1` what means overflowing it.
e.g. `extmap_short_is_valid_data()` has a bitwise operation
including length `(id << 4) | (ext->len - 1)`

Currently the function has two cycles (while-outer-cycle and
for-inner-cycle).
The inner one operates on the given `pp` pointer and can potentially
mutate it (the pointer isn't const), hence the outer cycle will
continue with a mutated pointer.
Instead just use a local scope pointer to manipulate linked list's
data.
P.S.: the `pp` pointer isn't a double pointer, so unlikely was
expected (even by design) to be modified (e.g. its address or what
it actually points to).

There seems to be a race condition with stream_fds/sockets being closed
while ICE checks are running at the same time, referencing the same
stream_fds. Solve this by holding a reference to the stream_fd in the
ICE pair object.
Additionally, add a check for a possibly closed socket when running
checks.

For-cycle expects the `sink_ml` for setting the `call_media`

is used, which is supposed to be used in the nested for-cycle.
Looks like a copy-paste typo. Major fix.

If someone wants to stop the media for this particular monologue,
and it already has the MP allocated, which is marked for MoH,
then just ignore the stop media command.
This is to not let the play media/stop media procedures
overlap with potentially (previously) triggered MP via MoH.

Both the play media and the music on hold use
the `media_player::call_play_media_for_ml()` as an entrance
towards the `media_player::media_player_new()` and
`media_player::media_player_play_init()`.
Prevent allocation of new MoH over ongoing one,
as well as the `play media` command over ongoing MoH.
Otherwise a media player will be re-used to override
ongoing activity.
Explicit policy must be used:
First the MoH has to be stopped
by getting back to the SDP `sendrecv` state, before
any other MoH request, or play media request can be fulfilled.

The `name` is caller-owned, while the cache itself
also keeps a separate key object

This can desynchronize the hash key and the list key.
