Convert remaining callers of lookup_blob to object_id

Browse source 
All but a few callers of lookup_blob have been converted to struct
object_id.  Introduce a temporary, which will be removed later, into
parse_object to ease the transition, and convert the remaining callers
so that we can update lookup_blob to take struct object_id *.
