[PATCH 08/10] revert: move replay_action, replay_subcommand to header

From

In our vision to build a generalized sequencer, the revert builtin will be left only with argument parsing work before calling into the sequencer. Since the enums replay_action and replay_subcommand have nothing to do with this argument parsing, move them to sequencer.h.

However, REVERT and CHERRY_PICK are unsuitable variable names for publicly exposing, as their purpose is unclear in the global context: rename them to REPLAY_REVERT and REPLAY_PICK respectively.
