bpo-33947: dataclasses no longer can raise RecursionError in repr (GF9916)
...
The reprlib code was copied here instead of importing reprlib. I'm not sure if we really need to avoid the import, but since I expect dataclasses to be more common that reprlib, it seems wise. Plus, the code is small.

Trivial dataclass cleanups: (GH-6218)
...
- When adding a single element to a list, use .append() instead of
+= and creating a new list.
- For consistency, import the copy module, instead of just deepcopy. This
leaves only a module at the class level, instead of a function.
- Improve some comments.
- Improve some whitespace.
- Use tuples instead of lists.
- Simplify a test.

If a non-dataclass derives from a frozen dataclass, allow attributes to be set.
Require either all of the dataclasses in a class hierarchy to be frozen, or all non-frozen.
Store `@dataclass` parameters on the class object under `__dataclass_params__`. This is needed to detect frozen base classes.
