Having a clean API for working with WAL independently of recovery
would let us have a maintainable xlogdump tool that doesn't constantly
get out of sync with the wal archive format. It would also make it
easier to write things like prefretching logic that requires reading
the upcoming xlog before its time to actually replay it.
