backup-files: Batch mass restore
When restoring all files, batch the first steps (directory creation
and target file removal) and last steps (optional touch and backup
file removal). This makes the typical restore case (quilt pop) much,
much faster.
Note: a similar optimization would be possible for the removal
function (-x), but quilt doesn't use this function at the moment.
