- added optional mode argument to popen2/popen3
  for unix; if the second argument is an integer,
  it's assumed to be the buffer size.

- changed nt.popen2/popen3/popen4 return values
  to match the popen2 module (stdout first, not
  stdin).

  for the moment, this argument must be left out or set
  to -1 (only the default bufsize is supported, that is)

  function is overridden by a python version which accepts
  *either* a string (old behaviour) or a locale tuple.

- renamed a few methods (for consistency):

        get_locale => getlocale
        get_default_locale => getdefaultlocale
        set_to_default => resetlocale (!)

- the _locale implementation module can now implement
  an optional _getdefaultlocale function.  if that function
  isn't available, a POSIX-based approach is used (checking
  LANG and other environment variables, as usual).

  note: to run this on Windows 95/98, you need to have the
  w9xpopen.exe helper in the same directory as the python DLL.

The actual test for it is only commented out in configure.in, so it can
be re-enabled if we ever run across the need for it again.

  just for the sake of it.

  note that this only covers the unlikely case that size_t
  is smaller than a long; it's probably more likely that
  there are platforms out there where size_t is *larger*
  than a long, and mmapmodule cannot really deal with that
  today.

  cast to make sure Py_BuildValue gets the right thing.

  this change eliminates bogus return codes from successful
  spawn calls (e.g. 2167387144924954624 instead of 0).

  this should be built as a console application (link with
  USER32.LIB), and installed in the same directory as the
  Python DLL.

was cascades of warnings about mismatching const decls.  Overall,
I think const creates lots of headaches and solves almost
nothing.  Added enough consts to shut up the warnings, but
this did require casting away const in one spot too (another
usual outcome of starting down this path):  the function
mymemreplace can't return const char*, but sometimes wants to
return its first argument as-is, which latter must be declared
const char* in order to avoid const warnings at mymemreplace's
call sites.  So, in the case the function wants to return the
first arg, that arg's declared constness must be subverted.
