Andre Puschmann d48bc8837e pdu: refactor MAC PDU class
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method

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 a7911f0dab 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

Andre Puschmann 035c369a43 mac_pdu: fix check of remaining length when adding new subheader to MAC PDU
when adding a new subheader to a MAC PDU we should only add the subheader
if at least 2 bytes are left in the PDU. Even a 1 Byte MAC Control Element requires
another byte to pack the subheader.

This fixes #1424 in which a 3 B MAC opportunity is provided in the UL. After
adding the Short BSR, we tried to add another MAC subheader. Adding the subheader
succeeded even though no space is left to add a single byte. With this patch,
adding the subheader fails and the generates MAC PDU is correct.
