Having maybe_null flag unset for geometry/spatial functions leads to wrong Item_func_isnull::val_int()'s results. Fix: set maybe_null flag and add is_null() methods. mysql-test/r/gis.result: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - test result. mysql-test/t/gis.test: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - test case. sql/item_geofunc.cc: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - set maybe_null flag for Item_geometry_func and Item_func_as_wkt. - moved length check to the beginnig of the Item_func_spatial_collection::val_str() to affect geometry collection objects at once. - changed Item_func_isempty::val_int() and Item_func_issimple::val_int() to properly handle null_value. sql/item_geofunc.h: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - set maybe_null flag for geometry/spatial functions. - added is_null() to Item_geometry_func and Item_func_spatial_rel classes. sql/spatial.cc: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - changed return type of Geometry::create_from_wkb() to be consistent with Geometry::create_from_wkt(), now it returns Geometry object or NULL in case of error. sql/spatial.h: Fix for bug #26038: X() value of empty NOT NULL POINT is neither NULL nor NOT NULL - changed return type of Geometry::create_from_wkb() to be consistent with Geometry::create_from_wkt(), now it returns Geometry object or NULL in case of error.
