indexer: do multiple passes over the delta list
Though unusual, a packfile may contain a delta whose base is a delta
that comes later. In order index such a packfile, we must not give up
on the first failure to resolve a delta, but keep it around.
If there is a pass which makes no progress, this indicates that the
packfile is broken, so fail accordingly.
