Currently the mapping between GSM 04.08 (GPRS) protocol specific
numbers and their textual description was put into gprs_gmm.c and not
exported.
This commit moves the mappings to a new file gsm_04_08_gprs.c,
renames some of them, and exports them via gsm_04_08_gprs.h.
The following identifiers are renamed to match the corresponding type
names:
- gmm_cause_names -> gsm48_gmm_cause_names
- gsm_cause_names -> gsm48_gsm_cause_names
