setup: move cffi stuff to mercurial/cffi

This patch moves all setup*cffi stuff to mercurial/cffi to make the root
directory cleaner. The idea was from mpm [1]:

  > It seems like we could have a fair amount of cffi definitions, and
  > cluttering the root directory (or mercurial/) with them is probably not
  > a great long-term solution. We could probably add a cffi/ directory
  > under mercurial/ to parallel pure/.
