* QPDFPageObjectHelper::removeUnreferencedResources can now be
called with a QPDFPageObjectHelper created from a form XObject.
The method already recursed into form XObjects.
* Rename some QPDFPageObjectHelper methods and make them support
form XObjects as well as pages. The old names will be preserved
from compatibility.
