It is interesting to know if a release was normal (as expected/requested
by the NAS layer, typically indicating a user-requested call end) or
abnormal (radio failure, pre-emption or whatever other event that the
user did not expect).

Add rate_ctr based statistics for RAB activation, deactivation and
failures. This requires us to parse RANAP in both uplink and downlink
and to iterate deep into the setup/modify/release/failure lists.
Given the way how the protocol works, the only way to distinguish an
activation from a modification is because sender and recipient know
whether a given RAB is already active at the time of the message. So we
also need to track the activation state of each RAB.
