The multi-statement detection did not check for the existence of
semicolons before doing the heavier processing.
Calculcate the packet length only once for the result state management.
The enums exposed by the connector are not intended to be used by the
users of the library. The fact that the protocol, and other, modules used
it was in violation of how the library is intended to be used.
Adding an internal mapping into MaxScale also removes some of the
dependencies that the core has on the connector.
The default database can now be manipulated with a set of functions
exposed by the maxscale/protocol/mysql.h header. This removes the need to
handle the structures themselves in the modules and is a step towards
moving the dcb->data contents inside the session.
The temporary table detection and handling now uses C++ containers to
store the set of temporary tables. The detection also uses the new query
classifier field info API to detect which tables and databases are
targeted.
