Reimplement batch-based background object/memory pool
...
Main changes:
- addition of pool utilities
- The node size/alignment and batch allocation threshold are now runtime arguments
- object pool and memory pool are not anymore based on the same class.
The object pool cannot use intrusive free list because it would overwrite the object
memory

Enhance RRC eNB events:
...
- Implement a common event "log_rrc" for all RRC events and discriminate by procedure using an enum.
- Log events for connection, reestablishment, reconfig, reject and release.
- Log the corresponding ASN1 message used by each procedure.
- Redefine the JSON object for this event to match the new structure.
Fixed a compilation error detected by the static analyzer in gcc9.3 where bounded_vector::data() was using taking the address of the internal buffer which confused it, prefer to use the data method of std::array.

enb,rrc: delay UE release after RLC maxRetx
...
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.
this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.
