Francisco f2a56c9139 simplification of multiqueue design.
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

Andre Puschmann 21b3635ae4 rlc_am_lte: refactor retransmit_pdu() to send different SNs
it seems that different SNs should be retransmitted depending
on the actual situation. In case of pollRetx timer expiration,
vt_s - 1 should actually be resent.

This patch prepares the function to accept different SNs but
leaves it to send vt_a by default. The RLC AM test would need
to changed as well to not fail.
