MessagePack structure bug in returned data

[hrbonz]

If you look at the issue I analyzed in influxdb-python, you will see that there is a suspicion of a msgpack issue in the server.
It was uncovered when querying 'SHOW DIAGNOSTICS' but I also got the exact same problem in "some" queries (that would be a bit trickier to debug as debugging involved reading the binary msgpack structure and validating it by hand)

I'm unfortunately not that comfortable with go and couldn't really track down the problem in the server code...
