	Oops - test code was only testing failure of around 30 of the
	mallocs in the test path, but it turns out there are 500+
	mallocs. I believe this was due to misguided linking setup such
	that there was one copy of dbus_malloc etc. in the daemon and one
	in the shared lib, and only daemon mallocs were tested. In any
	case, the test case now tests all 500+ mallocs, and doesn't pass
	yet, though there are lots of fixes in this patch.

	* dbus/dbus-connection.c (dbus_connection_dispatch_message): fix
	this so that it doesn't need to allocate memory, since it
	has no way of indicating failure due to OOM (and would be
	annoying if it did).

	* dbus/dbus-list.c (_dbus_list_pop_first_link): new function

	* bus/Makefile.am: rearrange to create two self-contained
	libraries, to avoid having libraries with overlapping symbols.
	that was resulting in weirdness, e.g. I'm pretty sure there
	were two copies of global static variables.

	* dbus/dbus-internals.c: move the malloc debug stuff to
	dbus-memory.c

	* dbus/dbus-list.c (free_link): free list mempool if it becomes
	empty.

	* dbus/dbus-memory.c (_dbus_disable_mem_pools): new function

	* dbus/dbus-address.c (dbus_parse_address): free list nodes
	on failure.

	* bus/dispatch.c (bus_dispatch_add_connection): free
	message_handler_slot when no longer using it, so
	memory leak checkers are happy for the test suite.

	* dbus/dbus-server-debug-pipe.c (debug_finalize): free server name

	* bus/bus.c (new_connection_callback): disconnect in here if
	bus_connections_setup_connection fails.

	* bus/connection.c (bus_connections_unref): fix to free the
	connections
	(bus_connections_setup_connection): if this fails, don't
	disconnect the connection, just be sure there are no side
	effects.

	* dbus/dbus-string.c (undo_alignment): unbreak this

	* dbus/dbus-auth.c (_dbus_auth_unref): free some stuff we were
	leaking
	(_dbus_auth_new): fix the order in which we free strings
	on OOM failure

	* bus/connection.c (bus_connection_disconnected): fix to
	not send ServiceDeleted multiple times in case of memory
	allocation failure

	* dbus/dbus-bus.c (dbus_bus_get_base_service): new function to
	get the base service name
	(dbus_bus_register_client): don't return base service name,
	instead store it on the DBusConnection and have an accessor
	function for it.
	(dbus_bus_register_client): rename dbus_bus_register()

	* bus/dispatch.c (check_hello_message): verify that other
	connections on the bus also got the correct results, not
	just the one sending hello
