Andre Puschmann 7726acad41 rlc_am_lte: fix counting of retx of entire PDUs and PDU segments 
this patch fixes a bug discovered in a real network where the DL CQI of a
user degraded repidly in very short time. A relativly big RLC PDU that
was still sent with the good CQI in a big grant now needs to be split
across many tiny segments because the CQI degraded so much.

The retx couting for each transmitted segment caused the retx counter to
reach maxRetx quickly.

With this patch we do not increment the retx counter for each transmitted
PDU or segment of a PDU but instead only increment the counter when
a given SN is added to the retx queue. This can happen either:
a) if the SN is negativly acknowledged and was not already on the retx queue,
b) no new data is available for tx and a SN is selected for retx.

This is in accordance with TS 36.322 which handles retx counting in section
5.2.1 according to the above description.

Andre Puschmann f292042f66 rlc_am_lte: use try-lock when building status PDU 
the patch uses try-lock whenever a status PDU is tried
to be built. This makes sure that when the lock is currently
hold (e.g. by a thread processing rx PDUs) the generation
of the status PDUs is not taking too long and blocking the calling
thread. Instead the status PDU generation is deferred to the next
Tx opportunity.

It's a probabilistic approach that assumes that at some stage the
lock can in fact be acquired.

faluco a70ad58440 Fix a data race in the UHD class wrapper where the last error member was being set concurrently causing random crashes. 
Introduce a new macro to catch UHD exceptions and log them directly instead of storing an error string, similar to what errno does.

faluco e20934583e Remove an unsafe assert in the log backend that could be triggered under very certain circumstances. 
RFCI has detected this assert failing in the log_backend_test. I have not been able to reproduce this locally but my theory is the following one:
one of the unit tests does the following:

backend.start();
backend.stop();

the internal running_flag member could be set to true and then to false by the main thread before the worker thread calls do_work(). If this happens
the assert will be triggered, which is wrong and too conservative, so remove the assert.

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 e1fb58d76e rlc_um: reduce log level for message handling lost PDUs 
when a lost PDU is detected a warning will be logged. In theory

in tests. The same event causes multiple other warnings to be logged,
which is very spammy. The patch reduces the log level for
those messages to info.

Without the check we were incorrectly processing the status PDU

correctly if ACK_SN is smaller than vt_a we were corrupting

when a small grant is provided it might not be possible to fit a full status

In order to avoid sending potentiall contradicting status info to the sending

has been received so far.

This might not be optimal in terms for retx but will not corrupt any
state.

Andre Puschmann f22f4b4fbd rlc_am: fix potential stalling in RLC transmitter 
it turned out that a certain order of events can lead to
a RLC transmitter stalling because even though unacknowledged PDUs
are queued, none of them was actually considered for retx.

This can happen if a pollRetxTimer expires for a SN that, meanwhile,
has already been acknowledged. The positive lead to the deletion of
the SN from the Tx window.

The fix makes sure that when a retx for a unexisting SN is requested,
the sender will consider the next unacknowledged SN instead.
