Convert remaining callers of sha1_object_info_extended to object_id

Convert the remaining caller of sha1_object_info_extended to use struct
object_id.  Introduce temporaries, which will be removed later, since
there is a dependency loop between sha1_object_info_extended and
lookup_replace_object_extended.  This allows us to convert the code in a
piecemeal fashion instead of all at once.
