* qt/tools/dbuscpp2xml.cpp: Compile on Windows. * qt/tools/dbusidl2cpp.cpp: Add missing newline.

	* qt/examples/Makefile.am:
	* qt/examples/chat.h: Use UI-generated files with the ui_*.h
	form.

	* qt/src/qdbusmarshall.cpp: Allow sending of QString() and
	QByteArray() (nulls) over the bus.
	* qt/src/qdbusabstractinterface.cpp: Use the correct variable,
	the one that has the signature suffix stripped.
	* qt/src/qdbusreply.h: Make some methods const.
