Implement support for paging based on LAC and CI. 

This is a simple combination of the LAC and CI cases which have
already been implemented.

The BSC_Tests.TC_paging_imsi_nochan_lac_ci ttcn3 test passes.

The switch statement in bssmap_handle_paging() is getting a bit large,
and scoping of local variables could be improved. I will focus on
cleaning this up later once paging functionality is complete.
