Subject: [PATCH] Filesystems statistics for sar (part 3): Display statistics

This patch makes sar display filesystems statistics collected by sadc.
No average statistics are calculated here (filesystems can be unmounted,
then mounted again, making average values meaningless). Instead, sar displays again
the list of filesystems.

(cherry picked from commit c8afab03c6a6a28e303613b203bf6c186c168524)
