Looks up a child element by the given full-path name.
Similar to gst.child_proxy.ChildProxy.getChildByName, this method
searches and returns a child given a name. The difference is that
this method allows a hierarchical path in the form of
child1::child2::child3. In the later example this method would
return a reference to child3, if found. The name should be made of
element names only and should not contain any property names.
