Philipp Maier 39c609b7c9 mgcp: use osmo-mgw to switch RTP streams
osmo-bsc currently negotiates the RTP stream directly with the
BTS and reports back the RTP IP/Port on the BTS. This works fine
for a single BTS, but for Handover the port/ip pointing to the
MSC side must not change, so an entity in between the BTSs and
the MSC is required.

Integrate the mgcp-client and use osmo-mgw to switch the RTP
streams.

Neels Hofmeyr 9eb208fcfb bssap: paging: page entire BSS for unimplemented cell id list
3GPP TS § 08.08 defines various types of Cell Identifier List IEs, but we only
implement "entire BSS" and "one LAC". If the MSC sends a Cell Identifier List
that we don't implement, it is best for interoperability to page the entire BSS
and post a log message instead of rejecting the paging altogether. Apart from
resource management, it is not harmful to page more than the MSC requested; if
use of resources becomes an issue, the log message will guide towards the
solution of providing an actually implemented Cell Identifier List IE.

Upon IE length that is other than we expect, log the error, but also fall back
to paging the entire BSS. Overall message length correctness has been checked
earlier.

The particular case observed is that a Huwaei MSC sends a LAI for Cell
Identifier List (MCC+MNC in bcd, followed by a LAC), parsing of which we may
want to add later.

Improve logging: identify the subscriber that is being paged.

Coding style: use a switch() statement to clarify flow and provide a place to
add more implementations later.

Add regression test bssap_test.c: fabricates BSSAP Paging messages with the two
implemented Cell Identifier List IEs as well as the unimplemented LAI
identifier, verify the resulting paging LAC in wrapped function and stderr.

Philipp Maier 718b0c72a0 log: output hexdump of transmitted sccp messages
We output a hexdump for each sccp message we receive, but not when
sending.

Also log the hexdump of sccp messages when sending.

Philipp Maier df78e48eb0 log: log the sccp message type of messages sent
We already log the message type of sccp messages we receive, but
for transmitting the log output is missing.

Also log the message type for tramsitted sccp messages.

Harald Welte 5de728564c Rename osmo_fsm to avoid illegal space in name + more meaningful name
A FSM doesn't need "FSM" in its name, as it is obvious that it is a
FSM.  Also, having two that are called RESET is confusing, so let's
try to come up with better names.

Also, after Change-Id I9ef59432f43a3cdb94e4cbb0c44ac3f9b2aac0f2 in
libosmocore, we now enforce that no FSM identifiers contain spaces
or other illegal characters.

Harald Welte 7b1d59c3c4 osmo-bsc: Initialize logging before initializing rate_ctr
The library code for rate counter initialization, which is called
from the descendants of bsc_network_alloc() might already want to
log something (particularly after Change-Id
Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 in libosmocore), so the
logging framework must be initialized before.

Neels Hofmeyr becfc4cb1b move to osmo-mgw.git: osmo-bsc_mgcp and libmgcp as libosmo-legacy-mgcp
Rewire build and includes to libosmo-legacy-mgcp.

Drop osmo-bsc_mgcp and related python tests, now found in osmo-mgw.git.

libosmo-legacy-mgcp is installed from osmo-mgw, hence add the dependency to
jenkins.sh (so far using the pre_release branch).

Philipp Maier 39f62bbcbf Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)
This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.

Implement AoIP in osmo-msc and osmo-bsc.

Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.

From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN

jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new
M3UA SIGTRAN.

Harald Welte 8f4a7c14af Treat SIGTERM just like SIGINT in our programs
When somebody kills the process, it's best to handle the signal
and to use the opportunity for some cleanup.  We always did this
in the NITB on SIGINT, but never on SIGTERM. Let's change it.

osmo-nitb becomes osmo-msc

add libiudummy, to avoid linking Iu deps in tests
Use new msc_tx_dtap() instead of gsm0808_submit_dtap()
libmgcp: add mgcpgw client API
bridge calls via mgcpgw

Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to
be split up.

This is the first step in creating this repository from the legacy openbsc.git.

Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.
