When adding object (or class) uint types, one must therefore use the generic property helper if a setter is needed. This enhances the uint-specific property helper APIs by adding a 'readonly' field and modifying all users of that API to set this parameter to true. If 'readonly' is false, though, the helper will add an automatic setter for the value.

This makes use of an enhanced API for object_property_add_uintXX_ptr() which offers default setters. Some of these setters used to update the value even if the type visit failed (eg. because the value being set overflowed over the given type). The new setter introduces a check for these errors, not updating the value if an error occurred. The error is propagated.
