[issue20653] Pickle enums by name

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Currently enums are pickled by values. It means that if the value of enum is platform depending, pickling one enum you can unpickle other enum on other platform.

Here is a patch which makes enum pickling by name. It also get rid of not needed __getnewargs__().
