factor out gen of USSD notify and release complete to libosmocore
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() functions, since there will be distinct subscriber connection structs. Rename to msc_send_ussd_notify() and msc_send_ussd_release_complete(), and add the same in libbsc with bsc_ prefix in new file gsm_04_80_utils.c. In preparation of this patch, the message generation part of these functions has been added to libosmocore as gsm0480_create_ussd_notify() and gsm0480_create_ussd_release_complete(). Use these. Adjust all libmsc and libbsc callers according to use the msc_* or bsc_* implementation, respectively. Change-Id: I33a84e3c28576ced91d2ea24103123431f551173
