VersionExtra holds, at runtime, the SHA256 of the packages being
added to try to avoid deduplicating obviously different packages;
the SHA256 itself is too large to store in the cache.
When volatile sources are used, the VersionExtra array is not
initialized, or rather it used to be initialized to 32*1024
zero elements as a performance optimization.
This meant that specifying --with-source with a package that
looks like a duplicate of a version with an ID >= 32*1024 triggered
the assertion; so we could not reproduce it easily in the test
suite.
Remove the optimized initialization to make the behavior more
uniform; and treat too large version IDs as having no SHA256.

Compare SHA256 to check if versions are really the same2023-08-02T10:04:32ZJulian Andres Klodejulian.klode@canonical.com2023-08-01T11:59:09Zurn:sha1:5576e7f76da73f3f5217f90d816cc19b6c0a5a77
If we know both SHA256, and they're different, the packages are. This
approach stores the SHA256 only at runtime, avoiding the overhead of
storing it on-disk, because when we update repositories we update all
of them anyhow.
Note that pkgCacheGenerator is hidden, so we can just modify its
ABI, hooray.

Test that tiny differences result in different versions2021-06-10T14:41:04ZDavid Kalnischkiesdavid@kalnischkies.de2021-06-10T14:41:04Zurn:sha1:e6056cbc8faf82c368d4439b0fcdcf4f46047d59
Just because two packages have the same version number doesn't mean it is
the same package. APT can detect rebuilds and other "inconsistencies",
but we had no explicit test for it so far. It turned out to be the wrong
track in this branch, but as I wrote it already, lets add it at least.
