Replace compile time version detection by runtime version detection

[pali]

Compile time macro MYSQL_VERSION_ID should be replaced by runtime function mysql_get_client_version() where possible. This allows to update system MariaDB/MySQL client library without need to recompile DBD::MariaDB XS module. Reason: Lot of Linux distributions compile DBD::MariaDB just once and not with every minor MariaDB/MySQL client library update.
