Cool. I've sync'd the branch to trunk, and it builds and passes
regression tests (though there are no tests for the new functionality).

Next, I'm making the format bump, FS-BDB format going from 4 to 5, and
making this successor-ids table conditional on format >= 5. Patch
attached. Is this correct?

After that, two possible next steps are:

  * to connect the APIs up through the layers (FS -> repos -> RA ->
client) so that a client can use it.

  * to add some tests at the FS layer.

  * to investigate how to do the equivalent in FSFS. (Stick a table in
the sqlite db?)
