In I4a07ece80d8dd40b23da6bb1ffc9d3d745b54092 I've introduced a
regression. According to GSM TS 04.11, section 2.3, SAPI 3 shall
be used for both MO/MT SMS transmissions. Due to a mistake,
caused by misunderstanding of the meaning of trans->dlci, SAPI 3
was not assigned to SM transactions if there is already an active
RAN connection with subscriber. Let's fix this.
Let's also drop this misleading comment:
/* FIXME: specify SACCH in case we already have active TCH */
because it's a task of the BSC/BTS to decide which lchan to use.

gsm_network contains an int handover.active which is always zero. Drop it.
There is real handover code coming up soon, one part of this is to avoid
confusion.
The internal MNCC code queried it to decide whether to MNCC_BRIDGE or proxy RTP
(MNCC_FRAME_RECV). Since RTP is being handled by osmo-mgw since forever, drop
that entire condition from mncc_builtin.

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.

According to GSM TS 04.11, section 8.2.3, the RP Message Reference
is a mandatory field for all messages on the SM-RL (SM Relay Layer),
that is used to link an RP-ACK or RP-ERROR message to the associated
(preceding) RP-DATA or RP-SMMA message transfer attempt.
This change extends the transaction state structure with SM-RP-MR,
and introduces a new function for matching transactions within a
given connection by this reference.

This is the first update since the libosmocore changes to the 'show
online-help' generated output. Hence the produced document now benefits from
the structural improvements:
- not repeating common commands for every node;
- using section names that match the VTY prompt.
Update msc_vty_additions.xml to match the new node ID scheme.

The initial goal was to make sure we don't have overall FORCE rules causing
unnecessary rebuilds -- annoying while writing documentation. As I looked
through possible dependencies, I finally understood what's going on here.
Remove code dup and nicely sort which belongs where in build/Makefile.*.inc. In
each, describe in a top comment how to use it, and also unify how they are
used:
- Rename Makefile.inc to Makefile.docbook.inc and refactor
- Add Makefile.vty-reference.inc
- Add Makefile.common.inc
Make sure that we accurately pick up all dependencies.
Drop use of the macro called 'command', that silenced the actual command lines
invoked and replaced them with short strings: it obscures what is actually
going on and makes the Makefiles hard to read and understand.
Each manual's makefile is greatly reduced to few definitions and a Makefile
include, e.g. one for asciidoc, one for VTY reference.
Move common/bsc_vty_additions.xml to OsmoBSC/vty/libbsc_vty_additions.xml, link
from OsmoNITB. It applies only to OsmoBSC and OsmoNITB.
Add a script that combines a VTY reference file with *all* additions files
found in a manual's vty/ dir. Call this from Makefile.vty-reference.inc.

It's much better to have both RP-DATA header parsing and validation
code in a single function. There is no need to pass all the header
fields (DA, OA, UI) to gsm411_rx_rp_ud() because they are not
used there.

Passing a message buffer containing the whole encoded message, and
a pointer to the RP header (struct gsm411_rp_hdr) is redundant.

When using smpp-first, after the ESME accepts our STATUS REPORT,
we were sending it locally into gsm340_rx_sms_submit() anyway.
In the case of the ESME mirroring the report back to us, this
would result in two copies of the status report in the SMS
database, which were also both then delivered to the MS.
This causes no visible error to the user but is a waste of radio
resources.
With this patch, we check if it is the sms_report that has had
receiver set in sms_route_mt_sms() and not the original SMS we
are reporting on, which of course already has receiver set.

the function vlr_subscr_req_lu() has a parameter is_ps, which is set
to vsub->vlr->cfg.is_ps by the only caller in vlr_lu_fsm.c. Inside the
function one can see that vsub->vlr->cfg.is_ps is used directly to
decide between PS or CS LU, we could also use is_ps there. Presumably
the parameter is_ps had been abandonned in an early development stage
and was not removed, so lets drop the parameter.

The function _handle_error() initalizes a struct gsm_mncc variable
on startup. The initalization accesses mgcp_ctx->trans->callref. All
this is done before the assertion on mgcp_ctx. Later in the code one
finds an if which tests on mgcp_ctx->free_ctx. This is the only part of
the code that accesses the mncc struct variable. We should move the
initalization there as well.
- Move initalization of struct gsm_mncc mncc into the if body
that uses it.

Move code which needs to test the mgcp_ctx->free_ctx flag upwards
such that it runs before we're calling functions which will
potentially free mgcp_ctx. The code being moved up takes effect
only in case mgcp_ctx won't be freed, so there should be no
functional difference.

At the moment osmo-msc populates the member ip in struct gsm_mncc_rtp
with the wrong byte ordering. This causes LCR or
osmo-sip-connector to receive the IP address in the wrong order, which
eventually leads into a reversed IP address in the SDP part of the SIP
messages.
