    Fix make check with --enable-warnings=fatal and fix make distcheck
    
    * tests/saxparser_chunk_parsing_inconsistent_state/main.cc:
    * tests/saxparser_parse_double_free/main.cc: Comment out names of unused
    parameters in function definitions.
    * Makefile.am: Add wrapped_exception.h to h_exceptions_sources_public or else
    it won't be distributed.
    * libxml++/exceptions/wrapped_exception.h: Add DOXYGEN_SHOULD_SKIP_THIS.
    xmlpp::wrapped_exception is a private class that shall not be included in
    the documentation. Bug #753570.
