Andre Puschmann 878142843e rlc_am_lte: add further sanity check when creating status PDU 
the test verifies that the ACK_SN of a status PDU falls inside the
rx_window of the receiver. If not, than the RLC state has been
corrupted and the status PDU is likely invalid.

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 aaffdeb326 rrc,rlc: add method to signal protocol failure to RRC 
general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.

In the current case, implement a direct release of the UE (enb) or
a reestablishment (UE).

Andre Puschmann f1e6a975de thread_pool: fix concurrent access of state variable 
the thread workers need access to their current state to exit properly
when they are set to state STOP. However, since the state is kept in
a std::vector for all workers, it seems more appropiate to add a per-thread
running variable rather then mutexing the entire vector.

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
