Change subject: Remove build dependency on legacy OpenBSC
......................................................................
Remove build dependency on legacy OpenBSC
* copy-paste gsm_data_shared.* from OpenBSC master
* remove corresponding configure check and option
* remove .deb dependency
Actual refactoring with removal of unnecessary structures/parts, moving
common OpenBSC/OsmoBSC parts into libraries etc. are left for further
patches.
Current patch will make coexistence with *BSC easier and will simplify
our build infrastructure.
