Applied with revisions. I didn't like the extra state you added to
track whether an xlog switch had occurred --- the more bits of
interdependent state the more chance for bugs, IMHO, and it seemed
unnecessary since it's easy enough to test whether we are at a
segment boundary. I also made the new user-level functions a bit
more orthogonal, so that filenames could be extracted from the
existing functions like pg_stop_backup.
