deprecate Branch.set_revision_history

[Jelmer Vernooij]

Branch.set_revision_history scales with the size of history - it's the main reason uncommit is slow on big trees.

It also complicates the Branch interface unnecessarily for foreign implementations.

There is no reason to use it over Branch.set_last_revision_info() (if we
are missing that api, we should add it.)

I think there is even one that lets you not know the last revno, and use
a revision. Which then uses a Graph object to determine the revno from a
couple of starting points.

I'm fine nuking it, or at least deprecating it, etc.
