Andre Puschmann 92d76a5eb6 mac_test: update tests involving BSR handling
* split existing BSR test into dedicated test for short, long, and trunc
  BSR tests

* update MAC tests that include packing UL BSR.
  (After checking TS 36.321 again it seems we have reported old UL buffer states)

Andre Puschmann 5e40bfe72c mac_pdu: unpack and print BSR index as well as BSR value in bytes
before the BSR was extracted but the actual index (between 0 and 63)
was not stored but directly converted into bytes.

for log parsing and debugging it is easier to follow the index
value. this patch therefore adds both values to the log message
and extends the API accordingly.

Andre Puschmann 9550bd3ef8 rlc: revisit interface for MAC and RRC
* add locked and unlocked version of has_data() since one is
  called from stack and one from PHY threads

* add comments in each interface section as to why locking
  is required or not

* remove RLC rwlock when not required

* move calls only used by RRC to RRC section

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

Andre Puschmann 218fa5cf55 ttcn3_dut: fix bug in DUT
reducing the sync queue len to 1 caused an issue when the
PHY was locking the mutex while trying to push a TTI event
on the stack.

instead of signaling the new TTI within the PHY, we now do it outside
in the DUT (after releasing the PHY mutex)

Andre Puschmann a5c0f96fa7 srsue: limit sync queue length to 1 for ZMQ radio
apply same change that we've done on the eNB also on the UE
to avoid the PHY processing TTIs faster than the stack.

Without that, we see lots of those in the logs:

...
08:39:17.580325 [STCK] [W] Detected slow task processing (sync_queue_len=7).
