Log Message:
Re-organise nhc98 to make it ready to use hierarchical libraries.

In this significant internal change, we rename some of the
compiler-specific implementations of Prelude types (e.g. IO) and
non-standard auxiliary functions (e.g. _apply1) to reside in the
NHC.Internal module.  This new module allows programmer access to
implementation details, without polluting the Prelude.

Also, the non-Haskell'98 libraries supplied with nhc98 are all renamed
to hierarchical variants within the NHC namespace. e.g.
  PackedString -> NHC.PackedString
  Binary -> NHC.Binary
etc.
