Python 3.8 (prep): Import Mapping etc. from collections.abc

Browse Source 
Python 3.3 moved various collections abstract base classes from
`collections` to `collections.abc`, but also kept them available in
`collections` for compatibility with Python 2. Python 3.8 will allow
importing only from `collections.abc`.

(`collections.abc` hasn't yet been added to six.moves; see
https://github.com/benjaminp/six/issues/155.)
