GdaFieldAttributes has been renamed GdaColumn

The GdaParameter is now an object, and it is extensively used within GdaParameterList objects. Each GdaParameterList object represent a vector of parameters (which may or may not have values assigned) and is the base of the GdaDataModelIter iterator object. The GdaParameter API has been altered.

The GdaExport class has been removed, the features it offered are now implemented in each GdaDataModel object.

GdaSelect has been renamed GdaDataModelFilterSQL

The GdaTable class has been replaced by the GdaDataModelQuery class: it's a data model which can refresh itself and can be configured to be updatable, it's not limited to a database table.

The GdaXmlDatabase has been removed and the default database is now SQLite which is a complete RDBMS in a file

All the gda_xql_*() functions have been removed because they were unused and unmaintained.

The 'xml' provider has been removed as it did not work correctly and has been replaced by the SQLite provider as the provider to have serverless databases.
