hnbgw: UE context: add handling by tmsi identification
To prepare for an upcoming commit that accepts TMSI identification upon UE
Register Requests:
Add tmsi arg to ue_context_alloc().
Add ue_context_by_tmsi().
This is aimed at the ip.access nano3G femto cell, as it apparently feeds
whichever identification the UE sends through to HNBAP (TMSI+LAI, pTMSI+RAI),
instead of an IMSI as expected.
See the upcoming commit that enables accepting TMSI identities for further
detail.
