Matthew Jordan a8276fe8ef Fix crash from bridge channel hangup race condition in ConfBridge ...

This patch addresses two issues in ConfBridge and the channel bridge layer:
1. It fixes a race condition wherein the bridge channel could be hung up
2. It removes the deadlock avoidance from the bridging layer and makes the
   bridge_pvt an ao2 ref counted object
