e2fsck: print runs of duplicate blocks instead of all of them
When pass1 finds blocks that are mapped to multiple files, it will
print every duplicated block. If there are long sequences of
duplicate blocks (e.g. the e_pblk field is wrong in an extent), this
can cause a gigantic flood of output when a range could convey the
same information. Therefore, teach pass1b to print ranges when
possible.
