	* libgda/sqlite/virtual/gda-virtual-connection.c:
	* libgda/sqlite/gda-sqlite-recordset.c:
	* libgda/gda-column.[ch]:
	* libgda/gda-data-model.c:
	* libgda/gda-data-model-import.c:
	* libgda/gda-data-model-array.c: removed gda_column_[gs]et_table(), gda_column_[gs]et_caption(),
	gda_column_[gs]et_scale(), gda_column_[gs]et_primary_key(), gda_column_[gs]et_unique_key(),
	gda_column_[gs]et_references() and gda_column_[gs]et_defined_size() as they were useless
	* libgda-report/engine/gda-report-engine.c: forgot to rename "spec-file" to "spec-filename"
	property
	* libgda/gda-data-select.c: added a "select-stmt" property to retreive (if available), the
	GdaStatement object which was executed in order to created the GdaDataSelect data model.
	* libgda/gda-data-model-iter.c: when the data model the iterator will be for is a GdaDataSelect,
	then use the SELECT statement to set some holder's properties (such as NOT NULL and default value),
	contributes to fixing bug #551058
	* libgda/sqlite/gda-sqlite-recordset.c: don't set GdaColumn's properties as we can't determine them
	correctly at this point, contributes to fixing bug #551058
	* libgda/sqlite/virtual/gda-virtual-connection.c: added missing header file
	* libgda/gda-data-select.c:
	* libgda/gda-data-model-dsn-list.c: correctly implement the get_value_at() virtual method
	* libgda/gda-util.c: bug fixed in gda_compute_unique_table_row_condition()
	* tests/: tests update
	* doc/C: doc. update
	* libgda/gda-data-model.h:
	* all GdaDataModel's implementations: added a new virtual method "i_iter_set_value" to
	allow data modifications from a GdaDataModelIter
	* libgda/gda-holder.[ch]:
	* libgda/gda-set.[ch]: added GdaHoler "before-change" and GdaSet "before-holder-change" signals
	to enable control over the values a GdaHolder can have
	* libgda/gda-data-model-iter.c: use the new GdaDataModel's "i_iter_set_value" virtual method and
	GdaSet's new signal
	* Altered all the signal's names to use the '-' instead of '_'
	* tools/gda-list-server-op.c: compilation warnings fixes
