Push patches for cabal-install to cabal-1.2

[Bjorn Bringert]

These two patches in cabal head should be pushed to the 1.2 branch to  
make cabal-install work with 1.2. We really want cabal-install to be  
buildable on GHC 6.8.1. I haven't done it myself since I don't have  
the setup for validating GHC stable patches at the moment.

   * Rename parseDescription to parsePackageDescription.
   This should be pushed to cabal-1.2 to make cabal-install work with  
1.2.
