qt-ble: add BLE packet debugging code

Browse source 
This is perhaps overly verbose, but the timing details helped figure out
some EON Core download issues, and it's nice to see when things actually
happen.

It's also good to see when the data actually enters our queues, and when
we read and write the packets.  That might help debug the issues Fabio
is seeing with the Mares Bluelink.
