Andre Puschmann 9c4146442a mac,phy: refactor NR MAC/PHY UL data passing interface 
inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU

RLC failure to deliver notifications and discard timer limits to 1500ms (#2368) 
* Added interfaces for the RLC to notify the PDCP of failure to transmit
SDU

* Limit discard timer to 1500ms, to avoid issues of lingering SDUs in the undeliverd_sdus_queue.

* Fix bug in early exit of notify_delivery and notify_failure

* fix compilation issue in rlc-pdcp notification

Pedro Alvarez fcaaf72187 Starting to add discard functionality to PDCP LTE entity. 
This includes:
  - Adding a queue (implemented with std::map) for undelivered PDUs.
    This queue uses the SN used for TX as the key.
  - Added discard timer that is started upon reception of the SDU. Upon
    expiry of the timeout a discard callback removes undelivered PDUs
from the queue.
  - Added the mechanisms to the notify_delivery to remove PDUs from the
    undelivered queue when the PDU is ACK'ed.
  - Added test case for both timer expiry and acknowledgment.
  - Fix up the getter for buffered SDUs to return the undelivered SDUs
  - Changed default PDCP discard timer, so AM has a discard timer by
    default.

Pedro Alvarez 7b25eac47c Fix race condition in rlc_am_stress test and other fixes related to this 
test. The race condition was being cause by write_sdu being called
simultanously to read_pdu, which could cause the read_pdu to try to get
the SDU info before it had been written by the write_sdu.

Changes in this commit include:
 - Make sure PDCP sn in included in RLC AM stress test.
 - Stop handling control PDU when TX is not enabled in RLC AM.
 - Fixed issue with length of the PDCP SN in rlc_stress_test.
 - Moved the place were sdu info erase was called to avoid double calls to erase
 - Tentative fix for race condition in rlc_am_stress test.
 - Added function to print information about undelivered_sdu_info_queue
   for debugging.

Pedro Alvarez de90b4753f Added the ability of the RLC AM to notify the PDCP of the acknowledged 
PDCP PDUs. This includes:

- Modifying the byte_buffer_t to include PDCP SN meta-data. This way,
  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.
