Changes for version 2.0
- major port to new MARIADB_PVIO structure (Pluggable Virtual IO) - so, yay, finally no more header file hacking because an official API exists, but since it is new, the PVIO api is quite broken, and due to the massive changes involved, not sure about backwards compatibility or stability. Seems to work for me.
- use mariadb_config or mysql_config commands to find includes and libraries.
