Change subject: Merge gsm_data_shared.h into gsm_data.h
......................................................................
Merge gsm_data_shared.h into gsm_data.h
Old _shared one comes from time where we shared header with other
componenets. It's no longer the case sine a logn time ago.
The gsm_data_shared.h is only being included by gsm_data.h nowadays, so
let's simply merge it to simplify header dependency and struct
definitions.
Similarly, gsm_data_shared.c is renamed to gsm_data.c
