scmutil: add option to register summary callbacks as transaction validators
We have a list of summary callbacks which are run after the transaction is
closed to show what has changed and what not. This patch makes it possible to
register those callbacks as transaction validators so that we can show summary
before committing the transaction and prompt user to accept the changes.
The goal of this is to implement `pull --confirm`.
