GERAN: allow GSM SRES on UMTS AKA challenge
Store the established security context type (GSM or UMTS) instead of the
boolean flag is_authenticated. Provide the previous boolean query with thin
sgsn_mm_ctx_is_authenticated() function.
Knowing which security context was established will be necessary for OS#3224,
i.e. using the proper ciphering key, which is not yet tested properly, and
probably not correct at this stage.
This change will make new SGSN_Tests.TC_attach_umts_aka_gsm_sres pass.
