SimpleLruTruncate() a page number that's "in the future", because it will issue a warning and refuse to truncate anything. Instead, we leave behind the latest segment. If the slru is not needed before XID wrap-around, the segment will appear as new again, and not be cleaned up until it gets old enough again. That's a bit unpleasant, but better than not cleaning up anything. Also, fix broken calculation to check and warn if the span of the OldSerXid SLRU is getting too large to fit in the 64k SLRU pages that we have available. It was not XID wraparound aware.
