Previously pg_stat_statements calculated the difference of buffer counters by its own code even while BufferUsageAccumDiff() had the same code. This commit expose BufferUsageAccumDiff() and makes pg_stat_statements use it for the calculation, in order to simply the code. This change also would be useful for the upcoming patch for the planning counters in pg_stat_statements because the patch will add one more code for the calculation of difference of buffer counters and that can easily be done by using BufferUsageAccumDiff().
