deprecating

[Simon Peyton-Jones]

Dear maintainers of

As discussed in Trac #6032 I am deprecating
          Rank2Types
          PolymorphicComponents
in favour of the single flag
          RankNTypes

Could you update your packages to match?  Until then we'll need to accept the deprecation warnings that GHC will produce when building them.

The change is backward compatible; older GHCs understand RankNTypes.

In addition to changing any LANGAUGE pragmas, there may be some changes to Cabal's flaggery.

Thanks

Simon
