Fix scoped type variables for expression type signatures

type signature, such as
e :: forall s. <type>
where 's' should scope over the expression e.

and treating quoted strings as atomic chunks.  Thus:
  :load a\ b c\"d e" "f

be used elsewhere.  I see no harm in modifying both to be consistent -- in fact,

    - Data constructors of a data/newtype family F can be exported and imported

    - This appears the most natural from a user's persepctive - although, it has a
      slightly different flavour than similar import/exports items for closed data
      types.  The data constructors denoted by F(..) vary in dependence on the
      visible data instances.
    - This has been non-trivial to achieve as RnNames derives its knowledge of what
      sub-binders an F(..) item exports/imports from the relation specified by
      Name.nameParent - ie, the constructors of a data/newtype instance need to
      have the family name (not the internal name of the representation tycon) as
      their parent.

    * Fix type checking of imported data instances
    - When reading a data/newtype instance from an interface, the data constructors
      have their own universals that do not necessarily match up with their tycon's
      type parameters.  (Whereas when type checking source, they are always the
      same.)
    - Hence, we need to be careful when building the wrapper signature of imported
      data constructors from data/newtype instances, and rename the type variables
      in the instance types appropriately.

    - Name generation for the internal names of indexed data/newtypes now uses
      the same counter that generates the dfun unique indexes (ie, class and type
      instances are counted with the one counter).  We could make this two
      separate counters if that's what's preferred.
    - The unique index of a data/newtype instances needs to go into the iface, so
      that we can generate the same names on slurping in the iface as when the
      original module was generated.  This is a bit yucky, but I don't see a way
      to avoid that (other than putting the full blown internal tycon name and
      coercion name into the iface, which IMHO would be worse).
    - The predicate for when a datacon has a wrapper didn't take GADT
      equations nor whether it comes froma  family instance into account.
