MXS-1703 Move more functions to MariaDBServer

Also, the QueryResult integer reading method now only reads non-negative integers
since the server rarely returns negative values. This frees negative values for
indicating parsing error(s).

Gtid-class was moved back to utility.hh/.cc because the QueryResult-class requires it.
