description:
Drop HAVE_WCHAR ifdefs from code that is not even compiled with !HAVE_WCHAR.

We still try to mainain the ability to build our curses with
!HAVE_WCHAR, but it doesn't make sense to provide stubs for new wide
API functions that just error out when !HAVE_WCHAR.  Any code that
only uses old API (and can work with !HAVE_WCHAR curses) doesn't use
those new functions.  The code that uses new API obviosly cannot work
when all the new API is stubbed out.

So the plan is to drop the stubs.  This commit does that for files
that are not even compiled with !HAVE_WCHAR (not only those stubs are
useless, they were not even there to begin with).

Same object code is generated for the normal HAVE_WCHAR case.  Nothing
is even recompiled for !HAVE_WCHAR.
