For some GGSNs we need to insert the PDP Charging Characteristics
that were returned. We receive these values from GSUP and will
fill them into the tlv structure when finding the ggsn context.

For the vty tests, add osmo-sgsn-accept-all.cfg (that does not need an HLR) and
use in vty_test_runner.py, otherwise the 'show sgsn' command will reply that it
could not connect to the HLR, failing the vty test which expects empty.

This helps in providing 3G software packages for the sysmoNITB hardware, which
uses 10.23.24.1 for SGSN and 10.23.24.2 for GGSN.
However, in order to not break the python tests, the osmo-sgsn.cfg example
still uses 127.0.0.1 as local address.
Change the GGSN address to 127.0.0.2, because SGSN and GGSN cannot co-exist on
the same address (the GTP port number is fixed by spec: no IE to communicate a
differing port, so it has to be the standard GTP port for both).

On incoming 04.08 messages, we log only the protocol discriminator in
decimal. Enhance: log pdisc and message type in hex, and also log the
protocol and message type as human readable string.
Also adjust the msc_vlr tests' log statements for wrapped rx/tx functions
of dtap from/to the MS.
Adjust the expected output of msc_vlr_tests.

The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.

libosmocore change-id I4efdb1eaae43aced33961b64d4f14b0040321c10 changes the
gsm340_gen_scts() from gmtime to localtime, meaning that by feeding a mere zero
as timestamp, we get different results depending on the local machine's
timezone setting. Instead of calling gsm340_gen_scts() with zero, simply write
a bunch of bytes as time so that the tests get identical SMS bytes every time.

Disable large parts of the code that depend on BSC presence. The code sections
disabled by #if BEFORE_MSCSPLIT shall be modified or dropped in the course of
adding the A-interface.
Don't set msg->lchan nor msg->dst.
Don't use lchan in libmsc.
Decouple lac from bts.
Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication:
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to
different interfaces depending on the actual subscriber connection.
While iu_tx() is going to be functional fairly soon, the a_tx() is going to be
just a dummy for some time (see comment).
Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer
and an indicator for the Integrity Protection status on Iu (to be fully
implemented in later commits).
Add lac member to gsm_subscriber_connection, to allow decoupling from
bts->location_area_code. The conn->lac will actually be set in iu.c in an
upcoming commit ("add iucs.[hc]").
move to libcommon-cs: gsm48_extract_mi(), gsm48_paging_extract_mi().
libmsc: duplicate gsm0808 / gsm48 functions (towards BSC).
In osmo-nitb, libmsc would directly call the functions on the BSC level, not
always via the bsc_api. When separating libmsc from libbsc, some functions are
missing from the linkage.
Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also
add a _tx to gsm0808_cipher_mode():
* add msc_gsm0808_tx_cipher_mode() (dummy/stub)
* add msc_gsm48_tx_mm_serv_ack()
* add msc_gsm48_tx_mm_serv_rej()
Call these from libmsc instead of
* gsm0808_cipher_mode()
* gsm48_tx_mm_serv_ack()
* gsm48_tx_mm_serv_rej()
Also add a comment related to msc_gsm0808_tx_cipher_mode() in two places.
Remove internal RTP streaming code; OsmoNITB supported that, but for OsmoMSC,
this will be done with an external MGCP gateway.
Remove LCHAN_MODIFY from internal MNCC state machine.
Temporarily disable all paging to be able to link libmsc without libbsc.
Skip the paging part of channel_test because the paging is now disabled.
Employ fake paging shims in order for msc_vlr_tests to still work.
msc_compl_l3(): publish in .h, tweak return value. Use new libmsc enum values
for return val, to avoid dependency on libbsc headers. Make callable from
other scopes: publish in osmo_msc.h and remove 'static' in osmo_msc.c
add gsm_encr to subscr_conn
move subscr_request to gsm_subscriber.h
subscr_request_channel() -> subscr_request_conn()
move to libmsc: osmo_stats_vty_add_cmds()
gsm_04_08: remove apply_codec_restrictions()
gsm0408_test: use NULL for root ctx
move to libbsc: gsm_bts_neighbor()
move to libbsc: lchan_next_meas_rep()
move vty config for t3212 to network level (periodic lu)
remove unneccessary linking from some tests
remove handle_abisip_signal()
abis_rsl.c: don't use libvlr from libbsc
gsm_subscriber_connection: put the LAC here, so that it is available without
accessing conn->bts. In bsc_api.c, place this lac in conn for the sake of
transition: Iu and A will use this new field to pass the LAC around, but in a
completely separate OsmoBSC this is not actually needed. It can be removed
again from osmo-bsc.git when the time has come.
Siemens MRPCI: completely drop sending the MRPCI messages for now, they shall
be added in osmo-bsc once the A-Interface code has settled. See OS#2389.

libvlr now delegates subscriber management to osmo-hlr, so the database no
longer represents a HLR. It basically only stores SMS, so reflect that fact in
the default database name.

Original libvlr code is by Harald Welte <laforge@gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>.
This is a long series of trial-and-error development collapsed in one patch.
This may be split in smaller commits if reviewers prefer that. If we can keep
it as one, we have saved ourselves the additional separation work.
SMS:
The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.
If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.
There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.
This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.
Introduce gsm_subscriber_connection ref-counting in libmsc.
Remove/Disable VTY and CTRL commands to create subscribers, which is now a task
of the OsmoHLR. Adjust the python tests accordingly.
Remove VTY cmd subscriber-keep-in-ram.
Use OSMO_GSUP_PORT = 4222 instead of 2222. See
I4222e21686c823985be8ff1f16b1182be8ad6175.
So far use the LAC from conn->bts, will be replaced by conn->lac in

- bscs.config needed by the vty tests was not picked up as a dist file, because
its suffix is not 'cfg'. Rename to *.cfg. Apply this rename in
vty_test_runner.py and osmo-bsc_nat.cfg.
- Remove restart counters after external tests, otherwise distcheck complains
about uncleaned files.
- Add contrib/ipa.py to EXTRA_DIST, hence add a Makefile.am to contrib/.
Otherwise the python tests cannot find that dependency.

Before, each GSUP client would contact the HLR with an identical unit id, i.e.
"SGSN-00-00-00-00-00-00", with the result that some messages were sucked off by
the wrong client.
Pass explicit unit name from each gsup client user, so that OsmoMSC is "MSC"
and OsmoSGSN is "SGSN". Hence the HLR can properly route the messages.
Todo: also set some values instead of the zeros.
Unrelated cosmetic change while editing the arguments: gsup_client_create()'s
definition's oap client config arg name mismatched the one used in the
declaration. Use oapc_config in both.

We are building with libosmo-sccp tag 'old_sua' until the new sigtran has
been applied. Since osmo-iuh commit
0f88c110093935305143987638e46dc6db304a3e
"migrate osmo-hnbgw to libosmo-sigtran's SCCP/M3UA"
osmo-iuh requires libosmo-sccp master. A similar 'old_sua' tag is in place in
osmo-iuh.git, to match libosmo-sccp 'old_sua'. Do that to fix the jenkins
build of --enable-iu.

When we are performing Rx sensitivity testing on a BTS, we want to
deactivate the connection failure criterion / radio link timeout, i.e.
no matter how many SACCH frames in uplink are failed to decode, the BTS
should never close the channel.
OsmoBTS Change-Id I736f21f6528db5c16fa80cdb905af20673797be5 covers a way
how this behavior can be requested from the BTS via an OML attribute.
This patch adds support to the BSC to actually set that attribute.
Do not use this in production networks, as the BTS will keep open radio
channels indefinitely even if the phone is gone and no longer
transmitting anything. This is a pure testing feature.

Previously the SI generation lead to setting the BCCH SIs for all TRX in
a multi-trx setup. This is because we create the SIs globally but
si_valid appears to be limited to the 'current' trx. Warn if we attempt
to set SIs for the BCCH on a trx that does not have a BCCH.

* add assertions for budget calculations
* generate multiple SI2q messages
* adjust SI2q-related tests
* use precise check for number of SIq messages instead of approximate
