mount options: add generic_show_options()
Add a new s_options field to struct super_block. Filesystems can save
mount options passed to them in mount or remount. It is automatically
freed when the superblock is destroyed.
A new helper function, generic_show_options() is introduced, which uses
this field to display the mount options in /proc/mounts.
Another helper function, save_mount_options() may be used by
filesystems to save the options in the super block.
