histedit: convert fold/roll actions into a class

This converts the fold/roll actions into a histeditclass instance, as part of an
ongoing effort to refactor histedit for maintainability and robustness.

The tests changed for two reasons:

1) We get a new 'empty changeset' warning because we now warn more consistently
between normal histedit and --continue about commits disappearing.

2) Previously we were not putting the histedit-source extra field on the
temporary fold commit during normal runs, but we were on --continue runs. By
unifying these code paths we now consistently put histedit-source on the
temporary fold commit, which changes some of the hashes in the backup bundles.
