When GATT services are discovered, added, and removed, profiles will
be notified using btd_profile device_probe and device_remove functions.
Since a single profile may handle multiple services from the same
device, it is useful to distinguish each btd_service by its service
handle range. This patch adds the start_handle and end_handle fields to
btd_service and an accessor for getting them, which reports failure if
the service was initialized without handles.
