* python/libstdcxx/v6/printers.py (StdListPrinter):
Add -D_GLIBCXX_DEBUG implementation changes. Receive typename from
printer registration.
(StdListIteratorPrinter): Likewise.
(StdDebugIteratorPrinter): New printer.
(build_libstdcxx_dictionary): Add -D_GLIBCXX_DEBUG registration
entries.  Always pass a typename where the type can change.
(StdSlistPrinter) Receive typename from printer registration.  Use
in printer output.
(StdBitsetPrinter): Likewise.
(StdDequePrinter): Likewise.
