This is about it on what can be disabled/deleted from libdbus
	easily, back below 150K anyhow. Deeper cuts are more work than
	just turning the code off as I've done here.

	* dbus/dbus-marshal-basic.c (_dbus_pack_int32): we don't need the
	signed int convenience funcs

	* dbus/dbus-internals.c (_dbus_verbose_real): omit when not in
	verbose mode

	* dbus/dbus-string-util.c, dbus/dbus-string.c: more breaking
	things out of libdbus

	* dbus/dbus-sysdeps.c, dbus/dbus-sysdeps-util.c: same

	* dbus/dbus-hash.c: purge the TWO_STRINGS crap (well, make it
	tests-enabled-only, though it should probably be deleted)

	* dbus/dbus-message-util.c: same stuff

	* dbus/dbus-auth-util.c: same stuff
