Bonnet Tun Exchanger Refactor: Drop the base class that barely did anything

TunDevicePacketExchanger had a base class that didn't do anything significant. Overcomplicates my efforts to refactor the exchanger for worker-thread writes.

Merge the little bit of behavior directly into TunDevicePacketExchanger and replace the base class with a pure interface.  Also, while at it, move the now-interface (and its mock) into the bonnet/ subdir and rename from QbonePacketExchanger to QBONE client packet exchanger to better describe its purpose.

Through some of the moved/modified logic, there may be some very minor changes to how the packets get logged/monitored, e.g. neighbor solicit packets (which are directly responded to in the exchanger) now get treated as a write packet rather than a read error.
