Deprecate SAX classes in Qt XML

Deprecated the SAX classes and disabled or replaced their uses in
tests if applicable.

Removed the saxbookmarks example, no point in keeping examples for
the deprecated code.

[ChangeLog][QtXml] SAX classes are now deprecated. Use QXmlStreamReader,
QXmlStreamWriter in QtCore instead.
