[Removed extra "test-suite" field in test-suite stanza

 Ignore-this: 4351031606d853474aadb09e393a52b9
 Ticket #215 (Overhaul support for packages' tests).  Previously, the test-suite
 stanza was allowed to contain a test-suite field, such as the executable stanza
 parser allows.  This was removed because it is only required by legacy support
 for executables and no legacy support is required for test suites.

 The problem was that we do the QA check on using the new version range
 syntax after parsing. The new syntax allows ()'s but previously the
 code threw them away in the parser stage. We now retain them in the
 AST and deal with them appropriately. This now allows the QA check to
 be accurate and detect things like "build-depends: base (>= 4.2)".

 The MIN_VERSION_<package> macros are useful to test whether we have at
 least a given version of a dependency, but we can't extract the actual
 version of dependency using this macro. This patch makes the version
 of each dependency available to the code of the cabal package, which
 can be useful when constructing global names in Template Haskell, for
 instance.

 When using "haddock --optghc-XTemplateHaskell" haddock will write out .o

 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.

 lets you look up by either. It also maintains the order of

 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)

       externalPackageDeps :: LocalBuildInfo -> [PackageId]

 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.

 InstalledPackageIndex rather than PackageFixedDeps pkg => PackageIndex

 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.

[Split requireProgram into two different functions
Duncan Coutts <duncan@haskell.org>**20090601174846
 Now requireProgram doesn't take a version range and does not check

 function requireProgramVersion takes a required program version
 range and returns the program version. Also update callers.
 Also fixes the check that GHC has a version number.

 With this change build-depends on a library within the same package

 they are explicitly banned, however this is another step towards

 behaviour if they specify they need at least cabal-version: >= 1.7.1

[Fake support for NamedFieldPuns in ghc-6.8
Duncan Coutts <duncan@haskell.org>**20081208180018
 Implement it in terms of the -XRecordPuns which was accidentally
 added in ghc-6.8 and deprecates in 6.10 in favor of NamedFieldPuns
 So this is for compatability so we can tell package authors always
 to use NamedFieldPuns instead.
