Recent 'add full SDP codec information to the MNCC...' patch has added a strict
CC state sanity check, which is too strict:
In tests with 200 concurrent calls, situations came up where the MNCC is faster
than the Abis in establishing a call. If that happens, the CC state machine is
already in GSM_CSTATE_ACTIVE when the RR channel assignment completes.
Also allow GSM_CSTATE_ACTIVE state for accepting an Assignment Complete.

This way osmo-msc can benefit from the complete codec information received via
SIP, which was so far terminated at osmo-sip-connector. osmo-sip-connector
could/should have translated the received SDP to MNCC bearer_cap, but this was
never implemented properly. Since osmo-msc already handles SDP towards the MGW,
it makes most sense to pass SDP to osmo-msc transparently.
To be able to send a valid RTP IP:port in the SDP upon the first MNCC_SETUP_IND
going out, move the CN side CRCX to the very start of establishing a voice
call. As a result, first create MGW conns for both RAN and CN before starting.
The voice_call_full.msc chart shows the change in message sequence for MO and
MT voice calls.
Implement cc_sdp.c, which accumulates codec information from various sources
(MS, BSS, Assignment, remote call leg) and provides filtering to get the
available set of codecs at any point in time.
Implement codec_sdp_cc_t9n.c, to translate between SDP and the various
libosmo-mgcp-client, CC and BSSMAP representations of codecs:
- Speech Version,
- Permitted Speech,
- Speech Codec Type,
- default Payload Type numbers,
- enum mgcp_codecs,
- FR/HR compatibility
- SDP audio codec names,
- various AMR configurations.
A codec_map lists these relations in one large data record.
Various functions provide conversions by traversing this map.
Add trans->cc.mnccc_release_sent: so far, avoiding to send an MNCC release
during trans_free() was done by setting the callref = 0. But that also skips CC
Release. On codec mismatch, we send a specific MNCC error code but still want a
normal CC Release: hence send the MNCC message, set mnccc_release_sent = true
and do normal CC Release in trans_free().
(A better way to do this would be to adopt the mncc_call FSM from inter-MSC
handover also for local voice calls, but that is out of scope for now. I want
to try that soon, as time permits.)

In this case we are fine with simply updating test result because anyway
ABI breakage in some libosmo-mgcp-client structs was needed, so new
versions of osmo-msc will require new versions of libosmo-mgcp-client.

So far, the cmdline argument was the only way to set a database file.
Add a similar config to VTY as 'msc' / 'sms-database'. The cmdline arg is stronger
than the 'database' cfg item. DB is not reloaded from VTY command.

"127.0.0.1" is changed to "localhost" to let local NSS decide whether to
use IPv4 or IPv6. In newish systems, IPv6 ::1 will be selected since
IPv6 takes precedence over IPv4.
Similarly, the default source addr needs to be changed from NULL to "localhost"
since for some yet unknwon reason, getaddrinfo(AF_UNSPEC, NULL) returns
first IPv4 "0.0.0.0" and later "::", which is inconsistent with
getaddrinfo("localhost") result, resulting in src=IPv4(0.0.0.0) and
dst=IPv6(::1), which is incompatible and will fail. In any case, since
the default remote address is a local one and it's the client side,
there's no real logical change since the kernel would anyway should have
taken a local address anyway.

We're already sending the RANAP CommonID message to the RNC,
let's do the same using BSSMAP CommonId towards the BSC. This
way the BSC knows about the IMSI of the served subscriber, which
is very useful for logging/debugging.

This byte is redundant, and must not be allocated in this function.
A consequence of this error is that the MS alwats interprets the
"Sub-channel" IE as test loop A regardless of the specified type.
Here is an example of malformed Close TCH loop (type C) message:
0f 00 00 04
x. .. .. .. - Skip indicator (see 3GPP TS 24.007)
.x .. .. .. - Protocol discriminator (see 3GPP TS 24.007)
.. xx .. .. - Message type (CLOSE_TCH_LOOP_CMD)
.. .. !! .. - (!) Redundant byte from create_gsm0414_msg()
.. .. .. xx - (!) The actual "Sub-channel" IE (loop C, X=0)

So far, by failing to initialize the cause value, we always send a Clear
Command cause == 0, which actually means "Radio Interface Message Failure".
This is seen in all my logged network traces of osmo-msc lab testing.
"Call Control" seems to be the only cause value that remotely fits a normal
release procedure, even if it was not voice call related, see 3GPP TS 48.008
3.2.1.21.

Move 'doc' subdir further down to "make sure" the osmo-msc binary is built
before the docs.
Remove msc_vty_reference.xml from the source tree.
In manuals/Makefile.am use the new BUILT_REFERENCE_XML feature recently added
to osmo-gsm-manuals, and add a build target to generate the XML using the new
osmo-msc --vty-ref-xml cmdline switch.

new_id_ptr should be passed as NULL if encoding the TMSI failed, so initialize
it accordingly.
Also add some bloat to better handle the case of an encoding error, even though
from code analysis that should not be possible here: there is enough buffer,
the MI is a TMSI encoded from a uint32_t...
The problem was introduced by Idfc8e576e10756aeaacf5569f6178068313eb7ea, before
which new_id_len was always 0 when no TMSI was present.

ran_peer.c is not the proper place to parse messages, because it should be RAN
agnostic. All parsing and encoding belongs in ran_msg_a.c and ran_msg_iu.c.
Move the Osmux TLV parsing into the is_reset_msg op: add supports_osmux
out-parameter (and add a logging fi pointer). To be able to modify msg->l3h,
also make the msgb arg non-const.
In ranap_is_reset_msg(), always return non-support for Osmux.
In bssmap_is_reset_msg(), return 0 if no TLVs were parsed, 1/-1 if an Osmux TLV
was present/not present.
Update the osmux support flag directly where the ConnectionLess message is
received, so that there is only one place responsible for that.

Adopt the same way to run manual vty transcript tests as in
osmo-bsc/test/Makefile.am.
There are different ways to select a specific test to run in osmo-bsc and here
in osmo-msc. The osmo-bsc way is more convenient when building outside the src
tree, because it does not need the full absolute path of the test file.

As soon as the subscriber is authenticated, update the VLR entry with the
MSC-A's full CGI, including the Cell Id received from the Complete Layer 3
Information.
Thus the Cell Id will be shown by vty 'show subscriber cache' and 'show
connection'.

makes more sense to print msc_a->via_cell.

Add only a long option to not clutter the cmdline namespace.
To add a long option without a short letter is slightly complex: use the 'flag'
and 'val' mechanism as in 'man 3 getopt' to write an option index to
long_option.
Make sure that all VTY commands have been added before parsing cmdline options:
move various VTY init further above. For msc_vty_init(), the global msc_network
already needs to be allocated, so also move that.

When msc_ho_send_handover_request() generates the HANDOVER REQUEST
message, it does not populate the call_id struct member.
In ran_msg_a.c the struct member call_id is used, but the
call_id_present flag is not set, which also prevents the call_id being
added to the message

This patch served for a manual testing counterpart for osmo-bsc to implement
MSC pooling.
This enables a basic MSC pooling setup, but for a production setup, osmo-msc
would still lack various features related to unloading subscribers to another
MSC as explained in 3GPP TS 23.236.

when the VTY write the config file ist prints the configuration line
for emergency-call in network and in msc, however the presence of the
configuration line in network leads to a parsing error on msc startup.
The vty command probably got moved to node msc and it was forgotten
to remove the printing from network.
