[issue11297] Make ChainMap() public in the collections module.

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

This is nice, but IMO there is some information lacking, e.g.:
- when an underlying mapping is mutated, does the ChainMap get updated too?
- does it work with arbitrary mappings or only with dicts or dicts subclasses?

I think new_child() isn't very useful. It seems two specialized for a one-liner. Ditto for parents().
