printers.py (StdListPrinter): Add -D_GLIBCXX_DEBUG implementation changes.

2009-10-01  Phil Muldoon <pmuldoon@redhat.com>

	* 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.
