Andre Puschmann c16ac6c890 ue_stack: only push sync event to event queue is stack is still running
stopping the UE in ZMQ mode caused a dead-lock because the Stack was
stopped before the PHY causing the sync queue to overflow. Since we
use a queue-length of 1 in ZMQ, mode, the PHY sync thread was blocking to
push a new sync event while the stack thread was already stopped.

this patch makes sure no new sync events are queued after the stack has
been terminated.

Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation

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 49a7a90698 mac: simplify BSR packing logic
simplify logic to check whether a BSR fits and, if so, which type.
before the check has been done in two places.

we now also accomodate for the CE subheader size.

Andre Puschmann 6364a4513c mac_pdu: fix issue when packing CE but no space left in PDU
we've not checked the return value when adding a new CE, like BSR or PHR,
for a UL MAC PDU. For very small UL grants, this could fail and
we need to remove the subheader again before packing the PDU.

This fixes issue #1649.

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 24dfb03b9d rrc: defer manipulations of the RLC/PDCP arrays
all calls that manipulate the RLC and/or PDCP arrays suffer
from a high deadlock risk if a PHY worker holds the RLC
AM Rx mutex at the same time when the stack wants to carry
out this reconfiguration.

this applies to RRC Reconfigs, but potentially also to RRC Connection
Reestablishment or even RRC Connection Setup, although this should
seldom be the case.

By breaking the call stack between RLC->PDCP->RRC->RCL and
carrying out the reconfig as a single task without holding the
RLC readlock the deadlock should not happen anymore.

This should fix issue #1593

Andre Puschmann 1199a79851 fix Scell sync for large cells
the PSS detection needs more temporary buffer than a full subframe.
we therefore need to allocate and initialize the sync object with
larger maximum size to support Scell search of large cells, e.g.
20 MHz

this fixes issue #1538
