sgsn: Cross-link gsm_subscriber and sgsn_mm_ctx
To implement subscriber based authorization a data structure is
needed that keeps the subscriber data. The MSC already uses a similar
struct named gsm_subscriber whose implementation is split into a
generic part (allocation, retrieval, reference counting, list
maintenance) and MSC related parts. For GPRS, only the generic part
will be used and specific fields may be added when needed.
This patch adds a field mm to struct gsm_subscriber that will be used
by the SGSN to store a reference to the current MM context (or NULL
if there is none). This also adds a field subscr to struct
sgsn_mm_ctx that reversely points to a gsm_subscriber (or NULL if
there is none). Either both fields are NULL or both fields are
non-NULL. Note that subscr is being reference counted.
