Andre Puschmann 6c82d63aa6 remove legacy PNF/VNF code 
the code hasn't been maintained for a while an likely needs to be
adapted for a real-world scenarios.

in order to avoid having to maintain two MAC/PHY interfaces we
remove the code from now.

Andre Puschmann 068267992d rnti_pool: add rrc_endc class and extra 1024B to UE memblock size 
this should fix #3045

however, this hard-coded size seems pretty unflexible anyway so we might
have to increase/add to it, or find an alternative way to calculate the size?

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack 
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.

Andre Puschmann 4b069d9b86 enb,mac: fix concurrent access to cell structs 
this patch moves the rwlock that protects the UE database outside
to also protect the cell struct.

It also adds a missing write guard when setting the cell
