Misc patches regarding corrupt rindex handling

Hi,

These patches are probably best handled as separate items, rather than as a set, but I didn't want to send out 11 separate emails.

This is a collection of patches I developed while debugging some rather complex problems involving the rebuilding of corrupt or missing rindex system files by fsck.gfs2. It also fixes some problems whereby gfs2_edit or other utils crash and burn due to corrupt rindex files.

Regards,
