configure fixed ARFCN per bts

Browse Source 
Remove ARFCNs as a concept from resource pool, assign a fixed ARFCN to
each BTS and TRX in the resource pools.

Using ARFCNs on specific bands as resources was an idea that is hard to
implement, because specific BTS dictate selection of bands which
influences which ARFCNs can be picked. That means reserving ARFCN
resources is only possible after reserving specific BTS resources, but
the tester is currently not capable of such two-stage resolution.

Writing handover tests, I got the problem that both BTS in a scenario
attempt to use the same ARFCN.

The by far easiest solution is to assign one fixed ARFCN to each BTS and
TRX. If ever needed, a scenario modifier can still configure different
ARFCNs.

(Due to uncertainty about OC2G operation stability, I prefer to leave
OC2G on ARFCN 50, as it happened to end up being configured before this
patch.)
