rmagueta 5e0307d845 Refactor code, add inter-freq neighbors, avoid mem leak 
Previously, we only supported intra-frequency handovers, so the
measurements where only for intra-frequency, reusing the same
measurement object. Now that we would support inter-frequency handover,
also add multiple MeasObjects for each neighbor.

 		c956de6f27 Trigger F1 Handover on A3 event 
When receiving a measurement report including an A3 event, trigger
handover towards the indicated cell.

Note that currently, we are still limited to one Cell by DU, hence
looking up a cell comes down to looking up a DU, as is done here.

rmagueta ecd941e946 Remove old RA process(es) when removing UE 
In handover, we might need to remove a UE that we knew under it's
C-RNTI, for which we also have the RA process. Hence, when removing a UE
by RNTI, remove it also from RA.
