	* bus/dispatch.c (bus_dispatch_test): OK, now finally actually
	write useful test code, after all that futzing around ;-)

	Test does not yet pass because we can't handle OOM in
	_dbus_transport_messages_pending (basically,
	dbus_connection_preallocate_send() does not prealloc the write
	watch). To fix this, I think we need to add new stuff to
	set_watch_functions, namely a SetEnabled function so we can alloc
	the watch earlier, then enable it later.

	* dbus/Makefile.am (libdbus_convenience_la_SOURCES): move
	dbus-memory.c to the convenience lib

	* bus/test.c: rename some static functions to keep them clearly
	distinct from stuff in connection.c. Handle client disconnection.
