      Replace the terms such as "Message Identifier" with "Packet Identifier" in all cases

      As Part of issue MQTT-17, it was proposed and agreed to use term "MQTT Control Packet" consistently and not "MQTT Command Message" in the specification.

      However this change causes a problem in understanding of another term "message Identifier". Comments and discussion may be needed on the use of word Message Identifier and if it should be called as Packet Identifier. I am opening this JIRA issue for further discussion in TC calls.

      example - from WD-04, line 383 - 385

      "A non zero message identifier (MessageId) MUST be present in the variable header of the following MQTT command messages: PUBLISH(where Qos!=0), PUBACK, PUBREC, PUBREL, PUBCOMP, SUBSCRIBE, SUBACK, UNSUBSCRIBE, UNSUBACK "

      In WD-05

      "A non zero message identifier (MessageId) MUST be present in the variable header of the following MQTT Control Packets: PUBLISH(where Qos!=0), PUBACK, PUBREC, PUBREL, PUBCOMP, SUBSCRIBE, SUBACK, UNSUBSCRIBE, UNSUBACK "

      Should message Identifier be called as Packet Identifier ?
