Thomas Zimmermann 649a51e22d Bug 1267214: Add |DBusConnectionDelete| for using |DBusConnection| with |UniquePtr|, r=shuang
The new helper |DBusConnectionDelete| deletes instances of |DBusConnection|
that are stored in a |UniquePtr|. It will close open connections before un-
ref'ing them.

For shared DBus connections, continue to use |RefPtr|.
