  revert: decouple sequencer actions from commands

  Currently, we have two actions "pick" and "revert" that directly
  correspond to the action of the commands 'git cherry-pick' and 'git
  revert' respectively.

Well, let's start here.  The two insns "pick" and "revert" and the
ability to mix them doesn't have much to do with the picture, does it?

I think the actual problem being solved is that insn types, as described
by the replay_action enum, are being abused to refer to top-level git
commands "revert" and "cherry-pick".  The sequencer isn't supposed to
care which top-level git command called it, except in some messages, so
we'd certainly like to stop pretending that has something to do with
insn types.

Based on what you've said, correcting this cleanly is complicated in
some places by the inconvenient fact that the sequencer _does_ care
which top-level git command called it.  (I haven't checked this; I'm
just taking it on faith from you.)  If we want to let other git
commands (like "git rebase" or "git sequence") call into the
sequencer, that sounds like a way bigger problem than any conflict of
terminology.
