Francisco 46cfdaf9e5 Handle case when old rnti gets removed during RRC reestablishment
This is achieved via:
- keep restarting the inactivity timer whenever a ReestablishmentRequest is received
- in case the RRC ReestablishmentComplete is very late and the old rnti was removed anyway,
  abort RRC reestablishment procedure and release new rnti

Andre Puschmann b2825d1280 mac_controller: after maxRetx disable ALL UE bearers
the reasoning here is that the only way to recover
from the maxRetx event is the UE attempting a reestablishment.

No further traffic, neither control nor data is scheduled
until then.

Andre Puschmann b61be7878a enb,rrc: split RLF counter and timer handling for DL/UL/RLC
this patch splits the counter and timer handling for PHY DL, PHY UL,
and RLC errors and makes sure that, for example, a successful DL
does not cancel the UL RLF timer, and vice versa.

They all use the same timeout value which is user-configurable.

Francisco 0d800eb8f6 stack, multiqueue - bugfix for multiqueue destruction, and addition of unit test 2021-05-10 15:27:21 +01:00
Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.
