Introduce experimental 'never' pinning for sources
This allows disabling a repository by pinning it to 'never', which is internally translated to a value of -32768 (or whatever the minimum of short is). This overrides any other pin for that repository. It can be used to make sure certain sources are never used; for example, in unattended-upgrades. To prevent semantic changes to existing files, we substitute min + 1 for every pin-priority: <min>. This is a temporary solution, as we are waiting for an ABI break. To add pins with that value, the special Pin-Priority "never" may be used for now. It's unclear if that will persist, or if the interface will change eventually. (cherry picked from commit 8bb2a91a070170d7d8e71206d1c66a26809bdbc3) LP: #1814727 (cherry picked from commit f52e7a2040f461fb37f88751f5a42a5d5c130441)
