Lots of people have pinned an older version that is no longer
installable, or more common yesterday, we saw a lot of people
who seemingly manually installed a newer version of a deb than
in the repositories, causing the package to be considered obsolete,
which does not make much sense.

solver3: Ignore Architecture: all for obsoleted-by2025-06-10T14:27:36ZJulian Andres Klodejak@debian.org2025-06-10T09:47:41Zurn:sha1:15f48dcd65fb17a4cb4cd1f93b872b3bb810c3b2
In case a new version of the source package is published, we
check that if there's a newer binary for the same architecture
and then consider the binary obsoleted.
This logic did not properly account for Architecture: all packages
which are considered as native architecture package with an "All"
multi-arch flag set, and hence a native architecture package may
inadvertently be considered obsoleted by a package that only built
on Architecture: all.
solver3: Do not prefer new installs over manually installed obsoletes2025-03-09T13:53:53ZJulian Andres Klodejulian.klode@canonical.com2025-03-09T13:52:53Zurn:sha1:5daf6dbfd272be2f8e3c59d4bab4be8c119b7aa1
Only move obsolete packages last that are automatically installed,
as we don't want to remove manually installed obsolete packages.
Add some missing const annotations to the operator[] arguments as
well that were needed.

solver3: Reject all non-candidates outright for strict pinning2024-12-03T08:44:18ZJulian Andres Klodejulian.klode@canonical.com2024-11-02T11:45:07Zurn:sha1:8f317d97c9fb821e839342ae445c824207678eb7
Reimplement strict pinning by rejecting the non-candidates when
translating the problem from the depcache to the solver. This is
substantially better than restricting the list of alternatives for
an or group to only include allowed ones for debugging purposes,
albeit a bit slower.
Fix obsoleted-by handling for experimental2024-08-12T14:05:54ZJulian Andres Klodejulian.klode@canonical.com2024-08-12T13:27:31Zurn:sha1:5d2c0e600656db690aaeb0768f3df8e71127808a
Basically this boils down to checking that the priority of the
source candidate candidate is higher or equal than the priority
of the package's candidate that is being under consideration.
It stands to reason if we maybe we should actually calculate a
source candidate version; this will look similar but may perhaps
perform slightly different.
