cindex: read-only association dump

This will eventually allow associating coderepos with inboxes
and vice-versa; avoiding the need for manual configuration via
tedious publicinbox.*.coderepo directives.

I'm not sure how this should be stored for WWW, yet, but it's
required since it takes about 8 hours to do this fully across
lore and git.kernel.org.
