debugformat: add a 'debugformat' command
The command displays basic data about all format variants registered for repo
upgrades. This gives a quick way to peek into a repository format.
The 'fm.write()' calls are very independent because more data will be added in
later changeset. Having more separate call make the later patch clearer.
