dbus: add ObjectPath type

Rather than use std::string for object paths, add a dbus::ObjectPath type
that wraps one while allowing more type-safety. This solves all sorts of
issues with confusing object paths for strings, and allows us to do
Properties code using templates disambiguating them from strings.
