ul_harq: don't clear payload buffer during HARQ reset
...
this fixes #1791 which was caused by a race between
the PHY workers preparing a new UL-SCH PDU and the Stack resetting
the MAC, which in turn resets the HARQ processeses, which cleared
the buffer and set the length to zero.
Not explicitly clearing the buffer on a HARQ reset seems to be
fine since the PHY worker clears the buffer before starting to
pack a new PDU anyway.

ue,rach: fix failing RACH proc when Msg3 grant RNTI matches current CRNTI

this was preventing that the Temp-CRNTI used in the RAR to be identical
to the currently configured C-RNTI of the UE.
The issue simply was that the RACH procedure was declared successful too
early, even before the Msg3 UL grant was filled with the Msg3 content.
The patch moves the logic that detects the successful completion of
the RACH procedure below the Msg3 packing.

the filter alpha was initialized to zero by default which causes an

because the filtering function will always return the current value.
According to 36.331 Sec 5.5.3.2 Note 2, a k-value of 0 should turn
off filtering, which should be used as the default value until
an update is received from the network.

It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.
It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.

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.

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

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

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

Previously we have only waited for SRB1 but the message can also be received on SRB2
and in this case both bearers need to be checked.
The method is now streamlined to check both SRBs and is also used when
checking the msg transmission of an detach request.
