Attached are changes for in-place upgrade for the latest errata for the
8.1 branch.  This only affects 8.1 - although some of the changes will
be merged into d10 as part of the upgrade framework very soon.  They
will be reviewed separately.

These scripts will be tested again once Matt's changes are in, to ensure
that everything is caught.  Its expected that there will be additional
issues to address.  I will update spec files then.

Matt, please review.
