hal_initialize() overrides other filter/object/fallback functions on separate connection

Hi,

My tests confirm this is correct; the bug was that the libhal message
filter function always returned DBUS_HANDLER_RESULT_HANDLED even though
we didn't handle the message. Now we return RESULT_NOT_YET_HANDLED for
messages we don't handle (which is less rude). I've committed the fix to
HAL CVS. So now your testcase won't fail.

I think this is an issue with D-BUS, yes, why would the filter function
in the DBusConnection from libhal receive messages bound for the
DBusConnection made in your main application?
