error in update on Release information changes
The value of Origin, Label, Codename and co can be used in user
configuration from apts own pinning to unattended upgrades.
A repository changing this values can therefore have serious effects on
the behaviour of apt and other tools using these values.
In a first step we will generate error messages for these changes now
explaining the need for explicit confirmation and provide config options
and commandline flags to accept them.
