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.

A commit refactored this code around one year ago, which broke osmux
detection of dummy messages. This commit partially reverts the earlier
commit and rearranges the existing code to make it more robust.

There's no need to separate between BSS and CN side nowadays, the
different types are used nowehere. This separation dates from
osmo-bsc-nat code days.

Documentation of rtp_bridge_cb was outdated, and caused confusion when
adding initial osmux support. Let's clear all the mess.

This way we have no more access to internal osmux structures.
Moreover, we already have similar information in our rate_ctrs, so
there's no need to print those there.

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
packets to us a while after we have closed the conn on our side,
specially if latency is high in the network (eg satellite links).

Let's not delay allocation of rate counters until the osmux conn is
fully enabled, since we may want to count stuff before that point in
time.
Fixes crash accessing null conn->osmux.ctrg in
MGCP_Test.TC_two_crcx_and_rtp_osmux_bidir.

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.
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.

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).

By default systemd will execute service with root directory (or home directory for user instance) which might result in
attempts to create files in unexpected place. Let's set it to 'osmocom' subdir of state directory (/var/lib for system instance) instead.
