Jeremy Drake 31e6c8ed34 WXMSW: use HandleToLong/LongToHandle functions.
On Clang++, casting from a pointer to an integer of a smaller size is
considered an error.  In cases where Windows HANDLEs are converted
to/from longs, use the Windows-provided conversion functions
HandleToLong and LongToHandle.

In a couple of cases, a pointer is being cast to long in a __hash__
function.  These don't seem Windows-specific so it is not safe to assume
the Windows conversion functions are present.  In those cases, fall back
to the (ugly) double-casting that the Windows functions contain.

doc="""\
This class provides a mechanism for mapping between Python objects and the
:class:`DataViewItem` objects used by the :class:`DataViewModel` for tracking the items in
the view. The ID used for the item is the id() of the Python object. Use
:meth:`ObjectToItem` to create a :class:`DataViewItem` using a Python object as its ID,
and use :meth:`ItemToObject` to fetch that Python object again later for a given
:class:`DataViewItem`.
By default a regular dictionary is used to implement the ID to object
mapping. Optionally a WeakValueDictionary can be useful when there will be
a high turnover of objects and maintaining an extra reference to the
objects would be unwise. If weak references are used then the objects
associated with data items must be weak-referenceable. (Things like
stock lists and dictionaries are not.) See :meth:`UseWeakRefs`.
This class is used in :class:`PyDataViewModel` as a mixin for convenience.
