sched - handle the case when the CRC is missing and max retx is reached

Enhance RRC eNB events:
...
- Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum.
- Log events for connection, reestablishment, reconfig, reject and release.
- Log the corresponding ASN1 message used by each procedure.
- Redefine the JSON object for this event to match the new structure.
Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.

rlc_am_lte: refactor PDCP/RLC interface to use fix sized data structure

this patch replaces the std::vector type used in the interface between
PDCP and RLC to signal delivery status between both layers. The new
data type is a configurable but fixed-size vector.
The RLC AM doesn't need to dynamically allocate the vector for every SN but
uses the tx_window for storage.

enb,rrc: delay UE release after RLC maxRetx
...
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.
this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.

the RLC can keep track of the ack'ed bytes for a specific PDCP PDU.
- Added in the RLC an `undelivered_sdu_info queue`, to keep track of the
amount of ack'ed bytes and the total size of the PDCP PDU,
so the RLC can know when delivery is finished.
- Added an interface between the PDCP and the RLC so that the RLC can
notify the PDCP when it receives an ack from the status PDUs. The RLC
passes to the PDCP a vector of all the ack'ed pdus in a rx'ed status PDU.
- Added some tests to the notify functionality. This includes some tests
where the PDUs are acked imediatly, and one test where the PDU is
retx'ed.

- Made RLC add_bearer() function capable of re-creating the RLC entity.
- Send RRC reconfiguration to the UE and reply to the EPC with S1AP
modify bearer response.

Bug fixes of srseNB scheduler TPC

- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.

If the UL grants are very sporadic, the SNR time window will never have samples
when a TPC is encoded
