    Move Win32 thread-safety stuff to hb-object-private.h
    
    The Win32 definitions for LONG, ULONG, etc conflicts with
    hb-open-type.h.  Avoid that by making sure hb-object-private.h
    and hb-open-type.h are not included in the same compilation unit.

commit 266b34418c9bbe23ccaf29cb354b58c465fa3b22
Author: Behdad Esfahbod <behdad at behdad.org>
Date:   Tue May 3 00:35:53 2011 -0400

    Refactor to keep hb-object-private.h and hb-open-type.h separate
    
    Needed to be able to include <Windows.h> from hb-object-private.h.
