When sd_device_enumerator_add_match_parent() is called multiple times, then previously set parents are discarded. This adds device_enumerator_add_match_parent_incremental() to make sd-device-enumerator scan devices under all specified parents. Note that for backward compatibility, sd_device_enumerator_add_match_parent() and udev_enumerate_add_match_parent() still discard previous assignments.
