revert: prepare to move replay_action to header

REVERT and CHERRY_PICK and are unsuitable names for an enumerator in a
public interface, because they are generic enough to be likely to
clash with identifiers with other meanings.  Rename to REPLAY_REVERT
and REPLAY_PICK as preparation for exposing them.
