[PATCH v4 01/25] sequencer: use static initializers for replay_opts

[Johannes Schindelin]

This change is not completely faithful: instead of initializing all fields
to 0, we choose to initialize command and subcommand to -1 (instead of
defaulting to REPLAY_REVERT and REPLAY_NONE, respectively). Practically,
it makes no difference at all, but future-proofs the code to require
explicit assignments for both fields.
