In ttcn3-msc-tests, so far we leave an intentionally failed MT SMS in the SMS
queue, which may cause it to re-appear in subsequent tests.
Allow removing all SMS for a given subscriber from the SMS database for good.
(I dimly remember a user report where the SMS queue spams failed SMS attempts,
and the only way to get rid of SMS for a given subscriber is to tamper with the
sms.db file directly. This should no longer be necessary with this command.)

Fixes: CID#178166 Array compared against 0 (NO_EFFECT)
It may happen that either the MS or an EUSE would become
unresponsive during a call independent SS session, e.g.
due to a bug, or a dropped message. In such cases, the
corresponding transaction would remain unfreed forever.
This change introduces a guard timer, that prevents keeping
'stalled' NCSS sessions forever. As soon as it expires, both
sides (i.e. MS and EUSE) are getting notified, and the
transaction is being released.
By default, the timer expires after 30 seconds. As soon as
either the MS, or an EUSE initiates any activity,
the watchdog timer is rescheduled.
The timeout value can be configured from the VTY:
msc
...
! Use 0 to disable this timer
ncss guard-timeout 30
Please note that changing the timeout value at run-time
doesn't affect the existing NCSS sessions, excepting the
case when the timer is disabled at run-time.
This change makes TC_lu_and_ss_session_timeout pass.

As a rudiment of OsmoNiTB, OsmoMSC is still involved in SMS
processing, storage (in SQLite DB), and routing (via SMPP).
In real networks this is done by the external entity called
SMSC (SMS Centre), while the MSC is doing re-encapsulation
of GSM 04.11 SM-TL (Transport Layer) payload (i.e. TPDU)
between SM-RL (Relay Layer) and MAP.
Since OsmoMSC itself is not a 'Network in The Box' anymore, it
makes sense to replicate the 'traditional' behaviour of MSC.
The problem is that this behaviour cannot co-exist with the
current implementation, so the key idea is to rip out the
local SMS storage and routing from OsmoMSC, and (re)implement
it in a separate process (OsmoSMSC?).
As a temporary solution, this change introduces a 'kill-switch'
VTY option that enables routing of SMS messages over GSUP
towards ESME (through VLR and HLR), but breaks the local
storage and routing. This is why it's disabled by default.
As soon as we move the SMS processing and storage away from
OsmoMSC, this behaviour would be enabled by default, and
the VTY option would be hidden and deprecated. At the moment,
this option basically does nothing, and will take an effect
in the follow-up changes.

So far the only way to use external MNCC is to pass the -M cmdline arg:
osmo-msc -M /path/to/socket
However, the osmo-msc.service file for systemd is installed by 'make install',
and hence it is quite impractical to depend on such a config item to be
required in the service file:
- It defies any scheme an operator may have in place to compose the
osmo-msc.cfg file -- this option doesn't go in the .cfg file but needs
separate action to add to the installed service file.
- After a make install or package upgrades / re-installations, this option will
be plain overwritten silently, or lead to the need for resolving file
conflicts.
The initial spark for this came from configuring the 35c3 GSM from cfg
templates.

In preparation for inter-BSC and inter-MSC handover, we need to separate the
subscriber management logic from the actual RAN connections. What better time
to finally rename gsm_subscriber_connection.
* Name choice:
In 2G, this is a connection to the BSS, but even though 3GPP TS commonly talk
of "BSS-A" and "BSS-B" when explaining handover, it's not good to call it
"bss_conn": in 3G a BSS is called RNS, IIUC.
The overall term for 2G (GERAN) and 3G (UTRAN) is RAN: Radio Access Network.
* Rationale:
A subscriber in the MSC so far has only one RAN connection, but e.g. for
inter-BSC handover, a second one needs to be created to handover to. Most of
the items in the former gsm_subscriber_connection are actually related to the
RAN, with only a few MM and RTP related items. So, as a first step, just rename
it to ran_conn, to cosmetically prepare for moving the not strictly RAN related
items away later.
Also:
- Rename some functions from msc_subscr_conn_* to ran_conn_*
- Rename "Subscr_Conn" FSM instance name to "RAN_conn"
- Rename SUBSCR_CONN_* to RAN_CONN_*

According to GSM TS 04.11, the SMC (Short Message Control) state
machine is a part of CM-sublayer of L3, that is responsible for
connection management (establisment and releasing), and SM-RP
(Relay Protocol) message delivery.
For some reason, the connection establisment request from SMC
(GSM411_MMSMS_EST_REQ) was not handled properly - it was
always assumed that connection is already established.
This is why the code initiating a MT (Mobile Terminated) SMS
transfer had to establish a radio connection with subscriber
manually.
Let's benefit from having the SMC state machine, and offload
connection establishment to it. This change makes the local
implementation closer to GSM TS 04.11, and facilitates the
further integration of GSUP transport.
NOTE: the expected unit test output is changed, because now we
always allocate a transaction first, and then establish a
connection, not vice versa.

- MS-initiated and network-initiated requests to establish

- successfully established MS-initiated and network-initiated
SS/USSD sessions (transactions) - "nc_ss:m{o|t}_established".

The only reason to use int instead of the enum was the lack of header
iu_client.h when not building with Iu support. Rather use the configure result
properly, include the header when Iu support is built and use the proper enum.
Omit the entire iu sub-struct when building without Iu.
Add LIBOSMORANAP_CFLAGS to libvlr, in order to find the iu_client.h header (now
also included from gsm_data.h).
Rationale: Instead of using a questionable typecast from int* to enum*, we can
now use the enum member directly without needing to silence compiler warnings.
