  * Add a Distribution.Setup module that re-exports Distribution.Simple.Setup
  Many Setup.hs files import Distribution.Setup so this unbreaks them.
  It's marked DEPRECATED so will generate a warning for scripts that use it.
  This patch is only going to the cabal-1.2 branch, not HEAD.

    M ./Cabal.cabal +1
    A ./Distribution/Setup.hs
