I think both would be justifyable, so I don't really care for now. One
slight reason for wrapping it in xlogreader.h is that we might add
compression of some form or another soon and it'd possibly be better to
have it in xlogreader.h so pg_xlogdump doesn't have to be changed. But
that's really rather minor.
