The BS-11 related tool bs11_config is currently not built due
to dependancy issues added by GSCON FSM.
- Re-Add bs11_config to makefile.am
- Add dependencies and stubs

Related: OS#2823
In the current implementation of osmo-bsc, the subscriber connection is
not handled (very) statefully. However, there is some state keeping in the
code that handles the mgcp connection, but there are still to much loose ends
which allow odd situations to happen, which then lead severe error situations
(see also closes tags at the end) This commit adds a number of improvements
to fix those problems.
- Use an osmo-fsm to control the gsm_subscriber_connection state and
make sure that certain operations can only take place at certain states
(e.g let connection oriented SCCP traffic only pass when an SCCP connection
actually exists.
Remove the old osmo_bsc_mgcp.c code. Use the recently developed MGCP client
FSM to handle the MGCP connections.
Also make sure that stuff that already works does not break. This in
particular refers to the internal handover capability and the respective
unit-tests.
See also OS#2823, OS#2768 and OS#2898
- Fix logic to permit assignment to a signalling channel. (OS#2762)
- Introduce T993210 to release lchan + subscr_conn if MSC fails to respond
The GSM specs don't have an explicit timer for this, so let's introdcue
a custom timer (hence starting with 99).
This timeout catches the following situation:
* we send a SCCP CR with COMPL_L3_INFO from the MS to the MSC,
* the MSC doesn't respond (e.g. SCCP routing failure, program down, ...)
The MS is supposed to timeout with T3210, 3220 or 3230. But the BSC
shouldn't trust the MS but have some timer on its own.
SCCP would have a timer T(conn est), but that one is specified to be
1-2min and hence rather long.
See also: OS#2775
- Terminate bsc_subscr_conn_fsm on SCCP N-DISC.ind from MSC
If the MSC is disconnecting the SCCP channel, we must terminate the FSM
which in turn will release all lchan's and other state.
This makes TC_chan_rel_hard_rlsd pass, see also OS#2731
As a side-effect, this fixes TC_chan_act_ack_est_ind_refused(),
where the MSC is answering with CREF to our CR/COMPL_L3.
- Release subscriber connection on RLL RELEASE IND of SAPI0 on main DCCH
The subscriber connection isn't really useful for anything after the
SAPI0 main signalling link has been released. We could try to
re-establish, but our best option is probably simply releasing the
subscriber_conn and anything related to it.
This will make TC_chan_rel_rll_rel_ind pass, see also OS#2730

All callers pass mcc=1, mnc=1, so just have it as default.
(Prepare for net->country_code etc to be replaced by net->plmn)

Move gsm_data.c and handover_cfg.c to libbsc, where they belong.
This leaves libcommon utterly empty, drop it.

The separation of gsm_data_shared.* from gsm_data.* historically allowed
compiling parts of it into osmo-bts, which we have dropped since (osmo-bts has
its own copy now). Even though gsm_data.* now becomes rather large by it,
remove the legacy separation to get rid of the "shared" naming, which is no
longer meaningful. A future patch might separate into meaningful smaller bits,
if we get the time.

Interestingly enough, talloc_ctx_init() actually had not a single caller.
While dropping it, see to it that the few contexts that are actually used in
osmo-bsc.git are indeed initialized in all the main scopes.
Also initialize two void* ctxts as NULL explicitly, to allocate under the NULL
context in case some main scope forgets to branch it off another root context.
(That's bsc, fle and paging, all others actually come in from other libraries.)

Provide concise log categories for each main scope.
Move the complete log categories 1:1 to osmo_bsc_main.c.
In bsc_nat.c, omit obviously unused log categories.
In tests, omit almost all log categories, except for those explicitly tested as
the expected output.
Note: should any logging occur for a log category that is omitted by accident,
such will end up being logged as DLGLOBAL, so it will show up and we can fix
it, and it will not get lost silently.

There still is a lot of dead code that we inherited from the NITB
days, let's remove more of it.
libtrau will be re-introduced as part of osmo-mgw later.

smpp_mirror is maintained in osmo-msc.git, so let's remove it
(and the associated libsmpp34 build requirement).

Simple patch to test the new status-report support code, remove previous
code before Delivery Acknowledgement support was in place. Use
LOGL_DEBUG for logging messages here as suggested by Neels and Harald.

Just munch and log SMPP delivery receipts by now, don't mirror this, it
is going to break things in openbsc.
Follow up patch removes this and mirrors this SMPP message as a
SUBMIT_SM with esm_class = Delivery Acknowledgement.

This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.
