[cp-patches] FYI: fix for Component.requestFocus

[Anthony Balkissoon]

This patch makes us pass
gnu/testlet/java/awt/Component/requestFocus.java.  requestFocus was
throwing a NPE unexpectedly.  When looking for our top-level ancestor,
we should start with ourselves if we are Containers, and if not, then
start with getParent().  Before we were just starting with getParent().

Also, if we find no top-level ancestor, we should just return (this is a
standard != null check before continuing).

        * java/awt/Component.java:
        (requestFocus): If this component is a Container, start here, not at
        its parent when looking for the top-level ancestor.  If no top-level
        ancestor is found (parent == null), return.
