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.
that allows to simplify the error handling.

ue_stack is changed to match new interface. This commit compiles
but doesn't work.

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
this could be info as well but a warning may help to detect issues
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.

Andre Puschmann 83bf5dcd49 rlc_am_lte: reduce time holding Tx mutex when processing status PDUs 
the patch is a re-implementation of the customer-specific optimization
we did in order to reduce the time the RLC holds the Tx mutex when
processing an incoming status PDU.

The patch makes sure to never operate on a raw mutex but instead
uses the deadlock-avoiding RAII lock.

Andre Puschmann 19f30aa652 rlc_am_lte: fix handling of out-of-order status PDUs 
before processing incoming status PDUs we should be checking
if the ACK_SN falls within our current Tx window. If not the PDU
will be dropped.

Without the check we were incorrectly processing the status PDU
and because the sequence number wrap around wasn't working
correctly if ACK_SN is smaller than vt_a we were corrupting
our Tx window.

Andre Puschmann 878142843e rlc_am_lte: add further sanity check when creating status PDU 
the test verifies that the ACK_SN of a status PDU falls inside the
rx_window of the receiver. If not, than the RLC state has been
corrupted and the status PDU is likely invalid.

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 a36e0477b8 rlc_am: fix status PDU packing when grant size isn't enough to send full report 
when a small grant is provided it might not be possible to fit a full status
PDU. This is currently detected while packing the PDU.

In order to avoid sending potentiall contradicting status info to the sending
entity, the fix makes sure to only transmit a small PDU acking what really
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.

Andre Puschmann 02cceee997 rf_zmq_imp: revert 28399dd876 and fix unit 
although the manual test with Amarisoft eNB worked fine it seems
the delay is still needed in the default case. Over 50% of the
tests failed in the nightly with:

[zmq] Error: tx time is 0.067 ms in the past (138240 < 139776)
[zmq] Error: tx time is 1.100 ms in the past (184320 < 209664)

While this usleep() should increase the pass likelihood it
still doesn't guarantee error-free runs, so we might need
to revisit it again as some stage.
