Harald Welte 28cd94427a 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.

Harald Welte 586e6819eb Migrate from gprs_apn_to_str() to libosmocore osmo_apn_to_str()
In 2015, Jacob moved/copied related functions to libosmocore, but
for some reason didn't remove the copies here.  Let's follow-up on
that and remove duplicated code.

The libosmocore commit introducing osmo_apn_to_str() was

Harald Welte 0f7013266b sgsn_vty: Don't assume pdp->lib is always valid
We can only print libgtp pdp information if a library context is
attached to this pdp context.  This is not always the case,
particuarly during some teardown scenarios.

Harald Welte 030e1973dd SGSN: Fix RAN information exposed on GTP during PDP CTX CREATE
In the PDP Context Create from SGSN to GGSN, we include information
about the RAN type (GERAN/UTRAN) and the Cell of the MS. This was
all hard-coded to GERAN, and wasn't updated when we added UTRAN
support to the SGSN.

Holger Hans Peter Freyther 3730de4d87 sgsn: Convert cch_pdp to host order for libgtp
libgtp is calling gtpie_tv2 which will convert this uint16_t from host
to network order. So far libosmogsm and the sgsn treated the charging
characteristics as opaque data. So when moving from byte array to the
uint16_t do the swapping.

Harald Welte 63dde0a44a gtphob: check for missing result of rate_ctr_group_alloc()
In case the counter group allocation fails, we must handle this
gracefully and fail the allocation of the parent object, too.

The recent change (Id I7dad4a4d52fe05f6b990359841b4408df5990e21) seems
to have missed one instance, so let's follow-up.

Holger Hans Peter Freyther 9d6f0625f7 sgsn: Fill the cch_pdp with a value coming from the tlv structure
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.

Neels Hofmeyr 84da6b1edb Implement IuCS (large refactoring and addition)
osmo-nitb becomes osmo-msc
add DIUCS debug log constant
add iucs.[hc]
add msc vty, remove nitb vty
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.

destination address, see Change-Id I5b5b6a9678b458affa86800afb1ec726e66eed88.

Harald Welte 2483f1b050 Use libvlr in libmsc (large refactoring)
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
Id3705236350d5f69e447046b0a764bbabc3d493c.

Neels Hofmeyr f2ba81303e gsup_client: allow passing a unit id to identify with HLR
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.
