revert: do not reverse hunks in interactive when REV is not parent (issue5096)
And introduce a new "apply" operation verb for this case as suggested in
issue5096. This replaces the no longer used "revert" operation.
In interactive revert, when reverting to something else that the parent
revision, display an "apply this change" message with a diff that is not
reversed.
The rationale is that `hg revert -i -r REV` will show hunks of the diff from
the working directory to REV and prompt the user to select them for applying
(to working directory). This contradicts dcc56e10c23b in which it was
decided to have the "direction" of prompted hunks reversed. Later on
[1], there was a broad consensus (but no decision) towards the "as to
be applied direction". Now that --interactive is no longer experimental
(5910db5d1913), it's time to switch and thus we drop no longer used
"experimental.revertalternateinteractivemode" configuration option.
