Reduce unnecessary reading of state variables back from the disk
during sequencer operation.

* ag/sequencer-todo-updates:
  sequencer: directly call pick_commits() from complete_action()
  rebase: fill `squash_onto' in get_replay_opts()
  sequencer: move the code writing total_nr on the disk to a new function
  sequencer: update `done_nr' when skipping commands in a todo list
  sequencer: update `total_nr' when adding an item to a todo list
