Log:
Prevent CDR backends from unregistering while billing data is in flight
This patch makes it so that CDR backends cannot be unregistered while active
CDR records exist. This helps to prevent billing data from being lost during
restarts and shutdowns.

associated with the current CDR for the channel, as opposed to a cumulative
measurement of all CDRs for that channel.
+ - CDR backends can no longer be unloaded while billing data is in flight. This
+ helps to prevent loss of billing data during restarts and shutdowns.

CEL:
- The Uniqueid field for a channel is now a stable identifier, and will not
change due to transfers, parking, etc.
