	This doesn't compile yet, but syncing up so I can hack on it from
	work. What are branches for if not broken code? ;-)

	* dbus/dbus-protocol.h: remove DBUS_HEADER_FIELD_NAME, add
	DBUS_HEADER_FIELD_INTERFACE, DBUS_HEADER_FIELD_MEMBER,
	DBUS_HEADER_FIELD_ERROR_NAME

	* dbus/dbus-hash.c: Introduce DBUS_HASH_TWO_STRINGS as hack to use
	for the interface+member pairs
	(string_hash): change to use g_str_hash algorithm
	(find_direct_function, find_string_function): refactor these to
	share most code.

	* dbus/dbus-message.c: port all of this over to support
	interface/member fields instead of name field

	* dbus/dbus-object-registry.c: port over

	* dbus/dbus-string.c (_dbus_string_validate_interface): rename
	from _dbus_string_validate_name

	* bus/dbus-daemon-1.1: change file format for the
	<deny>/<allow> stuff to match new message naming scheme

	* bus/policy.c: port over

	* bus/config-parser.c: parse new format
