5.0 replaces 3.1.1's handful of return codes with a single reason code
space shared across CONNACK, the PUBLISH acknowledgements, SUBACK,
UNSUBACK, DISCONNECT and AUTH.
NOTE:: anything below 0x80 is a success. Success, GrantedQoS0 and
NormalDisconnection are all zero, they simply read differently
depending on which packet carried them
