The optimizations relies on assumptions that are not valid with the
allow-uninst that has not been corrected. When these assumptions, we
end up with invalid nuninst counters.

When an allow-uninst hint is added for an unversioned binary package, items
are allowed to migrate, even if they make that binary package uninstallable
(on the architecture specified in the hint, if one was specified, or on all
architectures otherwise).
Using this hint should avoid using force-hint to allow specific breakage.

We allow this already now even though dpkg/1.19.1 is not in stable as
it will not cause issues with upgrades (only dpkg-checkbuilddeps
needed change, so it will not cause issues on the buildds as we can
rely on dpkg from buster being present there).

The recent code changes made use remove from the "binaries" field in
SourcePackages. Lists are not particularly optimized for this kind
of removal and we have a few source packages with a lot of binary
packages (e.g. libreoffice, gcc-X-cross{,-ports}) that might trip
poor performance.

This test checks if every binary in the target suite is listed as a binary for
its source package and vice-versa.
This adds a config option check_consistency_level:
0: no checks
1: only check at the end
2: also check for every hint run (default)
3: check for every transaction (slow - only useful for the testsuite)

This is a step towards making migration unit-testable. This step
reduces the need for global state (in the MigrationItem class as class
fields) and with another step we can remove the global state entirely
and enable unit tests to create migration items without having to
worry about other unit tests.

All types of dependencies between excuses (Depends, Build-Depends,
Build-Depends-Indep, ...) are handled by the same code. The DependencyType is
used to distinguish between the types where needed.

When we try to compute_groups for a group which has a source or a binary with
a lower version than testing, throw an exception. In the cases where this can
happen, the exception is caught. In other cases, it is not and it serves as an
assert.
This can only happen when there are multiple candidates (from multiple suites)
changing the same source or binary.
This should fix the ordering issues tested in these tests:
- tpu-unstable-binnmu
- binnmu-tpu
- tpu-with-unstable-binnmu
With this change, it should be possible to accept binNMUs from *pu again.

This isolates the undo handling in the new transaction object and in
doop_source, which currently generates the undo items. This commit
will be a stepping stone to rewriting the undo handling.

When calculating smooth updateable binaries, filter out cruft binaries from
unstable, because they will not be part of the set of packages that britney
will try to migrate to testing.

Admittedly, no policy adds them yet so this is currently no-op code.
However, future commits can start to rely on this infrastructure code.
