[issue16991] Add OrderedDict written in C

[Yury Selivanov]

Yury Selivanov added the comment:

Eric, is there any chance this can land in 3.5?  OrderedDict is a heavily used thing, everyone will benefit from a fast implementation.  It's OK if we have an imperfect (but fully compatible with existing OrderedDict) implementation in 3.5.  We can optimize it in 3.6.
