[PATCH] Do not regard old one-way links as errors (flapping test)

[Andrew Bartlett]

The dbcheck flapping test came up for me recently, and I figured out
what was going on and how to fix it.

Attached is a patch that passes 5 autobuilds on the Catalyst Cloud, and
should make dbcheck no longer flap.

Since we didn't choose to implement psudo-backlinks, we do not know
about one-way links when their target is renamed.  Instead we correct
them at runtime.  dbcheck now noticed the old names, and this caused a
flapping test.  We now change the code to still fix it, but not as an
error.

I already has this reviewed by Garming, but I had to change the
renamedc test to account for this no longer being an error. 

Please review/push!

Thanks,

Andrew Bartlett
