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.

When the item is a single binary cruft removal, the source name is different
from the package. compute_groups has this info anyway, so just pass it on as a
returm value.

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)

Note that this now also applies to binNMUs. A source block also blocks
binaries. Binaries on a specific architecture can be unblock with an
architecture-specific unblock hint.
This also means all binaries from non-primary suites
(testing-proposed-updates, etc) need approval.
Closes: #916209
Currently no policy implements this.
A policy can now implement apply_src_policy_impl or apply_srcarch_policy_impl
(or both), so apply_src_policy_impl is no longer an abstractmethod.

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.

The should_upgrade_srcarch method only needs _compute_groups for the
purpose of computing smooth update candidates. In the concrete case,
it is rather simple to inline that part directly (and fold away
irrelevant code).
This also enables us to rewrite _compute_groups to accept an migration
item as all remaining callers simply unfold the migration item into
the arguments required by _compute_groups. This change will come in a
future commit.

This makes it more explicit that we are not using the value for
anything (and its name did not match it content due to a mistake
in 5d49a41204).

Attempt the removal of the old libraries from smooth updates during every hint
run. In some cases, the removal needs to happen during the hint run for the
hint to succeed.

The "skip" value was a hack to support keeping cruft out of testing
while not breaking the undo code. With new the undo code
(a05a249e04), britney can now handle
this cause without the "skip" value and it has therefore out-lived its
purpose.

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.

The issue with an implicit rollback is that the caller has no idea
whether it should invoke rollback or not if an exception occurs.

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.

Support for binNMUs from *pu is currently broken, so disable it for now.

When building the excuses, don't calculate smoothbins for items not from
unstable.
This improves the change from commit db584d9fdc
Also try to make the code more readable.

When building the excuses, don't calculate smoothbins if the source is not in
unstable. Doing so would result in a KeyError and a crash. This happens for
sources that are in testing and (testing-)proposed-updates, but not in
unstable.

Support blocking the removal of a package with a removal hint. This is useful
to block an auto-removal.
Before this patch, only removals for packages not in unstable could be
blocked.
