Vadim Yanitskiy 72e0f09c03 gsm_04_14: fix off-by-one error in create_gsm0414_msg() 
This byte is redundant, and must not be allocated in this function.
A consequence of this error is that the MS alwats interprets the
"Sub-channel" IE as test loop A regardless of the specified type.

Here is an example of malformed Close TCH loop (type C) message:

  0f 00 00 04
  x. .. .. ..  - Skip indicator (see 3GPP TS 24.007)
  .x .. .. ..  - Protocol discriminator (see 3GPP TS 24.007)
  .. xx .. ..  - Message type (CLOSE_TCH_LOOP_CMD)
  .. .. !! ..  - (!) Redundant byte from create_gsm0414_msg()
  .. .. .. xx  - (!) The actual "Sub-channel" IE (loop C, X=0)

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.
