[New-bugs-announce] [issue39822] Use NULL instead of None for empty attrib in C implementation of Element

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Currently None is used instead of an empty directory for the attrib field in the C implementation of Element in ElementTree. It is a pure optimization: an empty dict takes a memory and its creation has a cost.

The proposed PR makes NULL be using instead of None. This simplifies the code.
