It's basically the same code path (one function calls the other), but it
makes a lot more sense to have it in the init function itself.

Parameters passed to several functions are rearrange to make code
simplier to follow, as well as dependencies between the different
functions. As a result, some parameters can be marked as const while
doing the change.

It's checked in all code paths being called, which makes sense since
it's impossible to send anything if the remote address is not set. Let's
check it once in a unique to simplify the code.

A new osmux bind-ip-v6 VTY command is added, similar to what's already
available for RTP. This way the user can decide whether to support IPv4,
IPv6 or both types of IP versions.
Both IP sockets are by default disabled, and must be explicitly enabled
by setting the bind-ip in the VTY configuration.

Since recently the port is guaranteed to be placed at
CRCX/MDCX in the sockaddr, hence we can check it using the API instead
of checking manually only for the address part.
In osmux_send_dummy() we actually fix a bug where an in_addr was being
compared against a struct sockaddr.

Let's use the port part of the struct mgcp_rtp_end->addr field instead
of keeping it separate. This makes it easier passing around and
using/checking the RTP remote address + port, and avoids confusion
having to check stuff outside of the address, with its port part
potentially unset.

This way we have no more access to internal osmux structures.
Moreover, we already have similar information in our rate_ctrs, so

Receiving an unknown CID (for which we don't have an active conn) is
totally expected at the end of the call, were some messages from the
peer may be send for a while, specially if latency is high.
If this occurs, we simply drop that batch and keep decoding the osmux
message in order to keep delivering content to other circuits.

This is actually quite common, since our peer may be sending some osmux

specially if latency is high in the network (eg satellite links).

Let's not delay allocation of rate counters until the osmux conn is

time.

During development of the counters, they were first added to the same

RTP related functions to increment the counters.
Let's add a seaprate set of helpers to update the correct osmux counter

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.
Change-Id: I173266c4058d5db9479d773d7dec1304bc8f1f99
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.

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.

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.

Usually only one MGCP client per application is present. Then the log
lines from mgcp_client.c will be distinguishable without additional
information. When the application is using a pool of MGWs, then the
various MGCP Client instances become hard to distinguish.

member. When no description is set, use the domain name.
- Output the pool member name on each log line in mgcp_client.c
