94b4c7dc21 Better error checking when setting 'this' in Python 
If python_append.i is modified to use:
__slots__ = []
instead of
__slots__ = ["this"]
then this additional error checking prevents a crash and shows a stack trace and error:
  AttributeError: 'ForSlots' object has no attribute 'this'

a01e8474f6 Fixing setting this in Python when using __slots__ 
Don't attempt to use the class's __dict__ for setting 'this' when
a user has extended a class with:
    __slots__ = ['this'].
Was segfaulting. Now we fall back to a simple PyObject_SetAttr if the
usual approach to setting 'this' in __dict__ does not work.

67e8334ac8 Python -builtin constructors silently ignored keyword arguments. 
Instead of silenty ignoring them, now a "TypeError: f() takes no keyword arguments"
exception is thrown if keyword arguments are used. Hence constructors and normal
methods/functions behave in the same way.

a628bf9b6f Python std::vector back-reference changes 
Give reference in container_owner a more unique name (back_reference).
Change back-reference 'ret' typemap to have a function name so that they
are less unwittingly be used elsewhere where not intended.

Note that they can be overridden by users if needed using:

%extend std::vector {
%typemap(ret)
  value_type const& __getitem__,
  value_type const& front,
  value_type const& back
  { ...  }
}

These override the SWIG supplied versions because the SWIG supplied
typemaps use non-const value_type&, but the methods use const, so the
above have a higher precedence in the typemap search algorithm.

3efea1f4ab Fix typecheck typemaps for non-pointers and NULL 
The typecheck typemaps succeed for non pointers (SWIGTYPE, SWIGTYPE&,
SWIGTYPE&&) when the equivalent to C NULL is passed from the target
language. This commit implements a fix for Python to not accept a Python
None for non-pointer types.
