The code to ban some filters for non-destructive usage was duplicated in a PDB file and in the XCF load code. Additionally to combining these 2 codes into a single gimp_gegl_op_nde_allowed(), this commit also moves part of the logic into gimp_gegl_op_blacklisted() which improves the following: * It used to be possible to create filters for hidden operations which were not returned by gimp_drawable_filter_operation_get_available(), such as "gegl:color" or "gimp:equalize", which would create all sorts of problems. Now trying to create these filters through the API will not work and will properly warn with an explicit error message. I do not consider this an API break since the filters were not returned in the available lists and therefore were not considered usable. Anyone who would have used any of these hidden filters was just going around a weakness in our implementation. * We make sure that our lists of allowed/forbidden filters are consistent across usages. * When getting the list of filters with gimp_gegl_get_op_classes(), we don't need to do an additional validation step (as we were doing until now in the PDB call). This is meant to imply that all returned operations were already validated.
