Pablo Neira Ayuso 83616a8e5f libmsc: SMS, Avoid premature RP-ACK to MS
There was one libmsc commit to openbsc that was
thus far missing in osmo-msc.

This commit completes the work on delayed response
from an ESME. Without this patch, the SMR sends
an RP-ACK to the mobile station, and subsequently a
DELIVER_SM_REPONSE from the ESME provokes either a second
RP-ACK, or an RP-ERROR; both of which result in
"unhandled at this state (IDLE)" from the SMR

After this patch, we have two things corrected:

1) RP-ERROR respects Deliver-SM error cause.
2) No more "unhandled as this state" error from the SMR

Extract from original commit message:
--------
libmsc: annotate esme route in the sms object from deliver_to_esme()

Annotate this esme route, so we can use it to return -EINPROGRESS to
skip sending premature RP-ACK to the mobile station, in case we're
handling sms routes through SMPP.
--------

About OsmoMSC
=============

OsmoMSC originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoMSC was one of the parts split off from the old openbsc.git. Before, it was
the libmsc part of the old OsmoNITB. Since a true A interface and IuCS for 3G
support is available, OsmoMSC exists only as a separate standalone entity.

OsmoMSC exposes
- GSUP towards OsmoHLR (or a MAP proxy);
- A over IP towards a BSC (e.g. OsmoBSC);
- IuCS towards an RNC or HNB-GW (e.g. OsmoHNBGW) for 3G voice;
- MNCC (Mobile Network Call Control derived from GSM TS 04.07);
- SMPP 3.4 (Short Message Peer-to-Peer);
- The Osmocom typical telnet VTY and CTRL interfaces.
