With this patch, Britney will correctly parse (and deparse) a
versioned Provides. Furthermore, she will allow it to satisfy any
unversioned dependency on the provided package.
This is the easy half of #786803.

It can be used to A) to make the mismatch check more efficient and B)
share identical binaries between suites.

Previously whether such packages received excuses, and the specific
content of such excuses, was dependent on the order in which their
binary packages were considered.

Technically, we simply sort by the "hint-size", but it for most parts
have the effect of putting single item earlier. Note this is /not/ a
perfect solution, but it is a simple heuristic exploiting the common
case.

This made iter_packages_hint a thin wrapper around try_migration, so
it was inlined into its only caller "do_all".

The callers of get_dependency_solvers need to do those table lookups
anyway. By moving it out, it is now possible to reuse the results.

Rely on the Installability tester to locate all of the affected
packages plus their transitive reverse dependencies. As the
InstallabilityTester is suite agnostic, the set of affected packages
now includes (versions of) packages not in testing, which is filtered
out during the check.

If we have an up-to-date arch all package available for this architecture,
that doesn't mean this architecture has an up-to-date build. We need an
architecture specific up-to-date package for that.

For fucked architectures, binaries from older versions are allowed to be in
testing, so we only remove them if they are gone from unstable.

Old binaries in testing are usually old versions of libraries that where
smooth-updated. These should only be kept in testing as long as they are
needed to install other packages in testing. When they are no longer needed,
they can be removed, even if the old library is still in unstable (where it
might be needed for reverse dependencies which are not in testing).
