obsolete: reports the number of local changeset obsoleted when unbundling

This is a first basic visible usage of the changes tracking in the transaction.
We adds a new function computing the pre-existing changesets obsoleted by a
transaction and a transaction call back displaying this information.

Example output:

  added 1 changesets with 1 changes to 1 files (+1 heads)
  3 new obsolescence markers
  obsoleted 1 changesets

The goal is to evolve the transaction summary into something bigger, gathering
existing output there and adding new useful one. This patch is a good first step
on this road. The new output is basic but give a user to the content of
tr.changes['obsmarkers'] and give an idea of the new options we haves. I expect
to revisit the message soon.

The caller recording the transaction summary should also be moved into a more
generic location but further refactoring is needed before it can happen.
