What kind of thing do you mean by branch-id here?  A human-assigned
short name, a global name, or something like a uuid?

Given our recent model clarification, the revision-history no longer
needs to be preserved; it's implied as the left-hand path through all
the revisions up to a tip.  (It will still be useful to cache it as a
fast way to get random access by revno.)

The most important thing stored for a branch is just a writeable pointer
to the tip revision of that branch.  Everything else, including the
revision history, can come out of this.
