Rework things a bit so the logic can be shared.

It turns out that some of the peak memory is actually during the inventory
to string to bundle translations. So re-use the refcount logic there.
This actually does show a decrease in peak memory.
Specifically 'cd bzr.dev; bzr send ../2.2' drops from 221MB peak to 156MB.

We don't speed anything up (16.5s both ways), but peak memory is quite
a bit better.
