[issue17394] Add slicing support to collections.deque

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Since the patch is so complex, I suggest to split it on parts, and review and commit them separately:

1) Refactoring. Extract common code to macros and utility functions. These macros can be used for more efficient implementing insert() and __del__.

2) Add slice getting.

3) Add slice assignment and deleting. I'm not sure that this is needed for deque.
