[svn-r23104] Purpose: Add object header flush dependencies
Description:
Added flush dependencies between object header chunks. Also added a new object
header proxy object, which is a child dependency of all object header chunks.
All objects which are child dependencies of an object header should set up a
flush dependency on the object header proxy, so the dependency applies to all
object header chunks.
Tested: ummon; jam (fails ph5diff -v, unrelated), koala, ostrich (h5committest)
