	* Land the new message args API and type system.

	This patch is huge, but the public API change is not
	really large. The set of D-BUS types has changed somewhat,
	and the arg "getters" are more geared toward language bindings;
	they don't make a copy, etc.

	There are also some known issues. See these emails for details
	on this huge patch:

        http://lists.freedesktop.org/archives/dbus/2005-January/001922.html

	* dbus/dbus-marshal-*: all the new stuff

	* dbus/dbus-message.c: basically rewritten

	* dbus/dbus-memory.c (check_guards): with "guards" enabled, init
	freed blocks to be all non-nul bytes so using freed memory is less
	likely to work right

	* dbus/dbus-internals.c (_dbus_test_oom_handling): add
	DBUS_FAIL_MALLOC=N environment variable, so you can do
	DBUS_FAIL_MALLOC=0 to skip the out-of-memory checking, or
	DBUS_FAIL_MALLOC=10 to make it really, really, really slow and
	thorough.

	* qt/message.cpp: port to the new message args API
	(operator<<): use str.utf8() rather than str.unicode()
	(pretty sure this is right from the Qt docs?)

	* glib/dbus-gvalue.c: port to the new message args API

	* bus/dispatch.c, bus/driver.c: port to the new message args API

	* dbus/dbus-string.c (_dbus_string_init_const_len): initialize the
	"locked" flag to TRUE and align_offset to 0; I guess we never
	looked at these anyhow, but seems cleaner.

	* dbus/dbus-string.h (_DBUS_STRING_ALLOCATION_PADDING):
	move allocation padding macro to this header; use it to implement
	(_DBUS_STRING_STATIC): ability to declare a static string.

	* dbus/dbus-message.c (_dbus_message_has_type_interface_member):
	change to return TRUE if the interface is not set.

	* dbus/dbus-string.[hc]: move the D-BUS specific validation stuff
	to dbus-marshal-validate.[hc]

	* dbus/dbus-marshal-basic.c (_dbus_type_to_string): move here from
	dbus-internals.c

	* dbus/Makefile.am: cut over from dbus-marshal.[hc]
	to dbus-marshal-*.[hc]

	* dbus/dbus-object-tree.c (_dbus_decompose_path): move this
	function here from dbus-marshal.c
