* dbus/dbus-message.c:

Browse source 
(dbus_message_has_path): New method
        (dbus_message_has_interface): New method
        (dbus_message_has_member): New method

        * dbus/dbus/dbus-sysdeps.c (_dbus_check_dir_is_private_to_user):
        New method

        * dbus/dbus-keyring.c (_dbus_keyring_reload): Check to see that
        the keyring directory is private to the user

        * doc/TODO:
         - The convenience functions in dbus-bus.h should perhaps have
         the signatures that they would have if they were autogenerated
         stubs. e.g. the acquire service function. We should also evaluate
         which of these functions to include, in light of the fact that
         GLib/Qt native stubs will probably also exist.: Punted

         - add dbus_message_has_path(), maybe has_member/interface:
         fixed in this patch

         - in dbus-keyring.c, enforce that the keyring dir is not
         world readable/writable: Fixed in this patch

GLib/Qt native stubs will probably also exist.
- the "break loader" and valid/invalid message tests are all disabled;
they need to be fixed and re-enabled with the new message args stuff.
I think I want to drop the .message files thing and just have code

- add dbus_message_has_path(), maybe has_member/interface
- protocol version in each message is pretty silly
Can Be Post 1.0
