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 9133135e12 rlc_tm: remove error from log when RLC TM PDU can't be sent
RLC TM can't be segmented so it may happen that a PDU
cannot be sent because the grant is too small. That is not
an error and should only be logged in info.

Andre Puschmann 55336665b9 rlc: remove timers and sdu queue length from RLC TM ctor

fine to be used at all times.

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 e8d6236975 remove init for all RLC TM/UM/AM
- all RLC entities are now initialized during contruction
- there is no need to check for, e.g., existance of timers, during
  runtime
- there is also no need to call re-init during resume
- timers are freed in dtor

Andre Puschmann c3441046c9 simplify RLC buffer status query procedures
- add a simple and low-overhead has_data() method to check whether
  an RLC entity has data to transmit or not
- use this method for all calls that are actually not interested
  in the amount of data to send
- use the more expensive get_buffer_state() for all cases where
  the actual size of the buffer is of importance
