Remove support for shared configuration cache
The configuration cache shared between packages, while being in principle a nice idea to speed-up the configuration of packages by avoiding repetitive identical checks, turned out to be unreliable due to the subtle differences between similar but not identical checks in different packages. After spending some time trying to fix those, we concluded that supporting the shared configuration cache is definitely too hard and too unreliable, and that we'd better get rid of it altogether. This patch therefore removes the shared configuration cache infrastructure and usage.
