the thread sleep waiting for the UE release should not run
on the stack thread. Move it to the UE class therefore.

Andre Puschmann 3173dedf0a ue_stack_lte: make sure to execute stack commands on Stack thread 
some commands were executed from the calling thread which may lead
to concurrent access to members. Detected by TSAN. The patch
moves all remaining calls (the majority was alread moved) to the
Stack task queue.

Andre Puschmann fb4dd3ba7b ttcn3: fix various races between SS and Stack thread detected by TSAN 
fixed through the right usage of mutexes in both TTCN PHY and syssim.
nested mutex locking is solved by calling SS from the PHY after
releaseing the PHY lock again.

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 7113e55d53 rlc: refactor RLC entity to use smart pointers for holding bearers 
this patch mainly modernizes the bearer creation to use smart pointers.

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.

Andre Puschmann 98a91a2057 sync: protect sync_state, access ue_sync object only from one thread 
races detected with TSAN, primarily the ue_sync object which isn't
thread-safe is accessed by all workers to set the CFO and by the
sync thread to receive samples (which read the CFO).

The patch introduces shadow variables that are updates from the
main thread before/after the sync is executed. The atomic shadow
variables can then be read from otherthreads without holding a
mutex, i.e. blocking the sync.

Andre Puschmann 018c734b09 dl_harq: fix unlocking of unlocked mutex bug detected by TSAN 
in the mac_test the tb_decoded() method was called twice for
the 2nd codeword, causig TSAN to complain about an unlocked mutex
being unlocked.

The patch resolves the potential issue only calling tb_decoded
for a grant/tb thas has a non-zero MCS.

The patch also adjusts the reset function to have a safe and "unsafe"
version to be called from inside the class, similar to other
classes where we do the same.

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.
- no differentiation between queues, in terms of notification features

Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class 
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.
