[Workaround the fact that haddock stomps on our precious .hi and .o files
Duncan Coutts <duncan@haskell.org>**20100408225156
 Ignore-this: 301321a9ad31195da3cf78d8a0a72edd
 When using "haddock --optghc-XTemplateHaskell" haddock will write out .o
 and .hi files. This is bad because it replaces the ones we previously
 built. This results in broken packages later on. Of course haddock
 should not do this, it should write temp files elsewhere. The workaround
 is to tell haddock to write the files to a temp dir.

 It does not work as intended and gives inconsistent results between
 cabal install and cabal configure. The problem with the approach was
 that we were filtering out the dependencies of non-buildable components
 at the end. But that does not help much since if one of the deps of
 the non-buildable component were not available then we would have
 failed earlier with a constraint failure. A proper solution would have
 to tackle it from the beginning, not just as a filter at the end.
 The meaning of build-depends and buildable: False needs more thought.

 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:

     to InstalledPackageIndex.

   - we now export

     to look it up in the InstalledPackageIndex, which is in the
     LocalBuildInfo)

 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.

 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.
