This would fit in as part of a general plan to s/xlog/wal/g throughout
our user-visible names and documentation.  Which seems like a good idea
to me; there's no need to expose two different terms for the same thing.

(I don't feel a great need to unify the terminology in the code, though.
Just in stuff users see.)
