During development of the counters, they were first added to the same
RTP counter group and later on split, but some places still used the
RTP related functions to increment the counters.
Let's add a seaprate set of helpers to update the correct osmux counter
group.

So far the implementation only allowed the remote CID being the same as
the one dynamically implemented internally.

This makes all lines operating on rate groups way shorter. The "ctrg"
naming is already used in tons of places in osmocom code.

struct osmux_handle, which is shared by several rtp_conn, is
attached to the trunk object, since the socket also attaches to it.

It makes sense to handle one osmux socket per trunk. Since we only so
far operate one RTP/osmux trunk, let's stick to that only one for
simplicity.

The struct osmux_handle is a shared structure which goes together 1-1
with libosmo-netif's struct osmux_in_handle, which is common to all CIDs
to be muxed together. Hence, it makes no sense to store a specific conn
object to it, since it actually manages several of them. Hence, all the
conn specific stuff must be handled beforehand, not at osmux deliver
time.

This cleans up all the code, and makes it a lot easier to add IPv6 support
later on (mostly only a matter of adding an IPv6 bind address in VTY).
Similar changes were done to the Osmux code being added to osmo-bts.

The local Osmux IP address (cfg->osmux_addr) was never applied in
generated MGCP messages. Instead, the RTP one was written into the
MGCP message.

This way we don't need to worry about implementation details (struct
size) in the future in case they change (they will).

Since libosmocore.git Change-Id
I5cb740702805693cc7f0a550e2e093f9bfdd507c, the IuUP stack can send INIT
event more than once, it sends one each time an IuUP Initialization
message is received.
This is done since potentially a peer could send an Initialization
message at any time with a different subflow size configuration. So
ideally we should update all osmo-mgw state regarding codecs, and
forward the Init starting the procedure on the other conn of the
endpoint.
However, this scenario is most probably not going to happen right now
and it would be a lot of work to implement and test,
and subsequent INITs we received will almost surely come from
retransmissions of the initial Initialization message, which means
content will not really change.
Hence, it makes sense to simply drop the receive message (the IuUP stack
already takes care of re-ACKing it) and let the endpoint state continue
with its ongoing procedures.

The initially merged IuUP API and implementation in libosmocore assumed
that RFCI with ID was always in the position of its ID inside the list
of RFCIs. This was the case for messages sent by ip.access nano3g as well
as our own osmocom implementation. However it was noticed that other nodes
from other vendors actually use other order, as allowed by the IuUP message
format.
Hence, we need to break the assumption and provide explicit ID
information in the list.
NOTICE: This commit implies an API change when using libosmogsm.
However, the previous API was never available in any libosmogsm release,
and only available in both libosmogsm and osmo-mgw master, so we are
only breaking compatibility between different master versions, which is
acceptable.

Make sure that RTCP packets do not enter the code path where AMR OA and BWE
is converted. The conversion will fail and the RTCP packet will be
dropped.

AMR that has the payload format bandwith-efficient is the same codec as
AMR that has the payload format octet-aligned. Its the same codec, and a
comparison of the codec info with the function codecs_same() should
return true (=equal).
The affected function codecs_same() is used by mgcp_codec_pt_translate().
When the egress payload type number is looked up, the ingress and egress
codec information is compared. When one end is using AMR in
bandwith-efficient format and the other end is using it in
octet-alingned format. Then the codec still must be recognized as the
same codec. Othersiwse the payload type number translation would not
work, even though the codec is the same on both sides.

Using "payload" there is misleading, the proper naming is payload type,
a well known term for RTP.

Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

This was previously broken and a free endpoint was requirted to dlcx *,
additionaly globally handling this is difficult due to different

codes, so just do it in the functions, they know best.
