Bertram Felgenhauer <int-e@gmx.de>**20091103165558
 Ignore-this: 422eaeca8c7246170931adecc8556f15
 The main effect of this change is that the PROFILING macro gets defined
 when compiling C files and profiling is enabled. This is useful for code
 that inspects closures.
 
 Caveat:
   The change relies on the fact that Cabal does not track dependencies
   of C files but recompiles them every time. If dependency tracking is
   added, we'll need different extensions for profiling and non-profiling
   object files.

 Distribution.Simple.LocalBuildInfo: 
 
   - the LocalBuildInfo record contains an index of the installed
     packages; this has changed from PackageIndex InstalledPackageInfo
     to InstalledPackageIndex.
 
   - ComponentLocalBuildInfo stores the "external package dependencies"
     of the component, which was 
       componentPackageDeps :: [PackageId]
     and is now
       componentInstalledPackageDeps :: [InstalledPackageId]
 
   - we now export
       componentPackageDeps :: LocalBuildInfo -> [PackageId]
     (since to get the PackageId for an InstalledPackageId, you need
     to look it up in the InstalledPackageIndex, which is in the
     LocalBuildInfo)
 
   - similarly, previously
       externalPackageDeps :: LocalBuildInfo -> [PackageId]
     is now
       externalPackageDeps :: LocalBuildInfo -> [InstalledPackageId]

 This part adds the InstalledPackageIndex type to
 Distribution.Simple.PackageIndex.  Now that packages have a unique
 identifier within a package database, it makes sense to use this as
 the key for looking up installed packages, so InstalledPackageIndex is
 a mapping from InstalledPackageId to InstalledPackageInfo.
 
 Distribution.Simple.PackageIndex still supports other kinds of package
 mappings: PackageIndex is a mapping from PackageName.
 
 All the functions in the section "Special Queries" now work on
 InstalledPackageIndex rather than PackageFixedDeps pkg => PackageIndex
 pkg:
 
   topologicalOrder,
   reverseTopologicalOrder,
   dependencyInconsistencies,
   dependencyCycles,

 Note: this patch doesn't build on its own, you also need the rest of
 the patch series.
 
 Compatibility with older GHCs.  When reading a package database
 created by an older version of GHC without installedPackageIds, we
 have to fake an InstalledPackageId for the internal
 InstalledPackageInfo.
 
 So, when reading in an InstalledPackageInfo from an older GHC, we set
 the installedPackageId to be the textual representation of the
 PackageIdentifier: i.e. <package>-<version>.  Now, previously the
 depends field of InstalledPackageInfo was [PackageIdentifier], and is
 now [InstalledPackageId], so we will read each PackageIdentifier as an
 InstalledPackageId (a String).  The dependencies will still point to
 the correct package, however, because we have chosen the
 installedPackageId to be the textual representation of the
 PackageIdentifier.

   NOTE: the patch has been split into 9 pieces for easy
   reviewing, the individual pieces won't build on their own.
   
 Part 1 does the following:
 
 Distribution.Package: 
   - define the InstalledPackageId type as a newtype of String
 
 Distribution.InstalledPackageInfo:
   - add an installedPackageId field to InstalledPackageInfo
   - change the type of the depends field from [PackageIdentifier]
     to [InstalledPackageId]
 
 
 The idea behind this change is to add a way to uniquely identify
 installed packages, letting us decouple the identity of an installed
 package instance from its package name and version.  The benefits of
 this are
 
   - We get to detect when a package is broken because its
     dependencies have been recompiled, or because it is being
     used with a different package than it was compiled against.
 
   - We have the possibility of having multiple instances of a
     given <package>-<version> installed at the same time.  In the
     future this might be used for "ways".  It might also be
     useful during the process of upgrading/recompiling packages.

 (ghc >= 6.6.1).
