revert: Save command-line options for continuing operation

In the same spirit as ".git/sequencer/head" and ".git/sequencer/todo",
introduce ".git/sequencer/opts" to persist the replay_opts structure
for continuing after a conflict resolution.  Use the gitconfig format
for this file so that it looks like:

  [options]
	  signoff = true
	  record-origin = true
	  mainline = 1
	  strategy = recursive
	  strategy-option = patience
	  strategy-option = ours
