the ranap_ / RANAP_ prefix.

Using the MSC numbers in the logtext is not very expressive,
ise the SCCP-Addresses instead.
When creating the sccp instance and user, use more parseable
string than "MSC No.: n"

The vty commands:
called-addr my_msc
calling-addr my_bsc
are not very expressive to the user. Change the command
names into something more expressive:
msc-addr my_msc
bsc-addr my_bsc
Also change the function and variable names accordingly

"calling_address" and "called_address" is not very expressive.

bsc_addr and msc_addr to increase readability of the code.

do not start unless the user has configured sufficient SCCP

The VTY technically allows setting custom values for the
SSN. However, SSN values and their purposes are well
standardized.
If the user has configured an SSN, check that is compliant
to the standard. If not, warn and ignore the setting by
using the stanard SSN.
If the user left out the SSN, automatically use the standard
SSN.

The BSC clears all connections on reception of a
BSSAP RESET, however, the RESET command must not
affect the connections of other MSCs.
Ensure that only the connections of the MSC who
actually sent the BSSAP RESET are cleared.

The current VTY implementation has no knowledge about the
libosmo-sccp nodes and therefor can not resolve parent nodes,
nor decide if we deal with a config node.

When the reset is started, state machines are allocated. The user
must provide a correctly filled structure where the reset start
function adds the state machine into.
This is prone to errors, besides of that, a proper deallocator
function which tears down the osmo fsm is missing.
make a more cofmortable allocator function and add deallocator
function.

Move osmo_sccp_simple_client() setup out of iu_init() and a_init().
In msc_main.c and sgsn_main.c, initialize the STP connection first and then
pass to iu_init() and a_init().
This allows serving 3G (IuCS) and 2G (A) from one and the same MSC instance.
Since both OsmoHNBGW and OsmoBSC are using PC 23 by default now, move BSC to PC
42 (because OsmoBSC typically has vty port 4242, bla).
Also:
a_iface.c: remove now unused defines
a_init(): remove osmo_ss7_init() call that duplicated msc_main.c

Currently we do not check for errors during the generation of
channel type and speech codec list. This might blow an assertion
in gsm0808_create_ass if the generated data is invalid. So
we need to check beforehand.

The log output from the rsl layer injects line breaks at wrong
places in the log. This messes up the logtext. This commit fixes
the problem.

When the mgcp_client prints MGCP strings in the log text, it does
not remove the line break before printing. This will mess up
the log text. This patch removes the line break characters before
printing properly.

The bsc side currently can not receive reset commands from an
MSC. This patch adds required functionality to receive a reset
command and acknowlege it properly. The effects are the same
as with when sending resets (all drop all ongoing calls and
sccp connections)

The AoIP standard also describes an MSC->BSC reset procedure. We
currently do not implement it. However, the fsm that is used to
issue the reset request from the bsc side is not generalized. This
patch generalizes the code in order to be able to use the same
code on the MSC side to perform a reset procedure from there.

the old sccp-lite based imlementation offered support for sending
an USSD notification as soon as a loss of the MSC connection is
detected. This is done before forcefully dropping the affected
connection.
This commit ports the feature to the new libosmo-sigtran
implementation.
NOTE: I do not know if this works and I also do not really
understand how this is even possible. Sending an USSD notification
would rquire the subscriber to be properly attached? When the MSC
is lost this almost not possible since no backend to authenticate
against is available.

The function names in a_iface_bssap.c are not very expressive.
The problem not only exists on the API side, but also for static
functions. This patch replaces the function names with more
expressive names.

The function names if the API function in a_iface.c are not
very expressive. Besides of that, the prototypes are in the
wrong header file. This commit gives the function more
expressive names and moves the prototypes in the right header
file.

it adjustable.

Clearing all endpoints by sending a DLCX on startup has ben found
to be a bit too offensive. It also will not help against
inconsitancies that may occour during runtime (e.g. an overheard
DLCX during regular call teardown).
This reverts commit b669ea94cb78fd9b56ee8dd9392538151349f8ba.

The MSC is aware of the assigned endpoints at all times, so it
will not assign an occupied endpoint to someone else. However,
if it has just restarted, there maybe lingering open endpoints.
This patch introduces a fairly simple soultion. Before a new
endpoint is seized (CRCX), a DLCX is send in advance. If the
endpoint was still occupied with a dead connection, it will
be freed. If it was free anyway, the DLCX will just have no
effect.

When the BSC is vanishing, the subscriber connections will stay
active until the MSC is instructed via tha A interface to clear
the connections. Unfortunately, this will most likely not be
the case because the BSC will most likeley have lost all its
state and does not know about the old connections anymore.
This patch fixes the problem by looping through the list with
the active gsm subscriber connections and clearing them manually
when the reset from the BSC is received. Only connections by the
bsc who actually executes the reset are affected. Connections
from other BSCs will not be touched.

If the MSC is crashing and restarting, it may leave some endpoints
open. The endpoints can not be re-used until they are deleted
(DLCX). This patch sends a DLCX to all possible endpoints (usually
this is in a countable range) in order to clear possible open
endpoints from a previous run
