 - Remove Giant from msync(2).  Giant is still acquired by the lower layers
   if we drop into the pmap or vnode layers.
 - Migrate the handling of zero-length msync(2)s into vm_map_sync() so that
   multithread applications can't change the map between implementing the
   zero-length hack in msync(2) and reacquiring the map lock in
   vm_map_sync().
