* Update doxygen annotations in libosmocoreHarald Welte2016-05-051-7/+9
| | | | | This adds and improves doxygen API descriptions all over libosmocore, reducing the 'white spots' that don't have any documentation.
* Add T4 bit map compression routinesMax2016-02-181-0/+480
Add bit map encoder and decoder functions: decoder is fully functional while encoder is good enough for testing - no backtracking to find the best possible compression is implemented. If somebody is willing to implement MS side of EDGE than this has to be expanded. Add corresponding tests. N. B: the encoding is implemented according to ETSI TS 44.060 which is slightly different from T4 used for fax according to CCITT G31D (RFC 804).
