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 c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

this patch makes sure that if RBs have been deactivated after
max KO on either the DL or the UL, they are reactivated if either
of them is working again.

UL/DL are always activated together, even if just one of them
recovers. The KO counter (or timer), however, is not stopped implicitly.

Francisco f2a56c9139 simplification of multiqueue design.
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
