Neels Hofmeyr 086bd33f18 add GAD coding for Location Services 
GAD, Universal Geographical Area Description:
- raw coding for all GAD elements.
- SI-units encoding and decoding for Ellipsoid point with uncertainty circle,
  which I presume is the typical "at most N meters away from cell tower located
  at X,Y", which corresponds to the TA positioning currently being implemented.
- other SI-units GAD element encodings are so far not implemented.

Add encoding and decoding tests.

In gsm/protocol/gsm_23_032.h are the raw coding structs as defined in 3GPP TS
23.032.

In gsm/gad.h are structs carrying consistent units based on meters and degrees,
for convenient / less error prone handling of GAD data, and for human readable
representations of the GAD data.

The separation of the two is desirable because OsmoBSC will receive GAD data
from OsmoSMLC on the Lb interface, and pass on this data to the MSC via the A
interface. It is better to pass the GAD data as-is without de/encoding.

README.md

libosmocore - set of Osmocom core libraries

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.

The libosmocore.git repository build multiple libraries:

  • libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
  • libosmovty contains routines related to the interactive command-line interface called VTY
  • libosmogsm contains definitions and helper code related to GSM protocols
  • libosmoctrl contains a shared implementation of the Osmocom control interface
  • libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
  • libosmocodec contains an implementation of GSM voice codecs
  • libosmocoding contains an implementation of GSM channel coding
  • libosmosim contains infrastructure to interface SIM/UICC/USIM cards
