Harald Welte c0847d641c SMPP: Don't accept password or system-id exceeding spec length 
The SMPP 3.4 specification defines the password field as a
"Variable-length octet string with maximum length of 9", and according
to table 3-1 this means including the terminating NUL-byte.

However, OsmoMSC allows to configure longer passwords in the ESME
configuration. Those passwords will then never match, as libsmpp34
performs length validation and generates a parser error for anyone
trying to send a longer password via SMPP.

The same applies for system-id, where we have to permit only 15
characters with zero termination, but not 16 characters.

Change-Id: I81ef593e84bf1e15f6746386fc145495fae29354
Closes: OS#3166

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.
