The PiupartsPolicy does not use the report URL for testing, so we do
not need to store it in memory. Unfortunately, the logic was broken
and the discard did not happen.

If a package had:
Build-Depends: foo [i386], uninstallable-pkg
Then the excuses for amd64 would point to "foo [i386]" rather than
"uninstallable-pkg".

Add a new "BuildDependsPolicy" that will check the satisfiability of
the build-dependencies listed in the Build-Depends and
Build-Depends-Arch fields. This enables gating of packages based on
missing / broken build-dependencies.
There are some limitations:
* Build-Depends-Indep is ignored for now. Missing or broken packages
listed in Build-Depends-Indep will be continue to be silently
ignored.
* Being a policy check, it does not enforce "self-containedness" as
a package can still migrate before a build-dependency. However,
this can only happen if the build-dependency is ready to migrate
itself. If the build-dependency is not ready (e.g. new RC bugs),
then packages build-depending on it cannot migrate either (unless
the version in testing satisfies there requirements).

We basically use them as sets and do not need to rely on the ordering,
so we might as well just turn them into proper sets.

Rewrite _compute_scc to be iterative to avoid call recursion limit for
graphs with long dependency chains.

Sometimes the solver would correctly compute which items are grouped
together, but then fail to emit some groups. This is trivially
fixable by forcing an update of "before" + "after" relations.
Admittedly, this looks unnecessary, so it may just be hiding the bug.
Nonetheless, the change makes the new test_solver_simple_scc test
produce the expected result.

devscripts' grep-excuses expects each <li> to be on its own line. When
d7a676d074 added the verdict summary,
without an EOL, it broke grep-excuses' ability to search by maintainer.

With this change, Britney can now provide a very brief summary of the
migration via one single value (YAML) or line (HTML). This solves two
issues:
* It provides an aggregated version of the policy decision without
having to loop over all policies (and even those would not give
a full verdict on their own as not all rejections come from
policies)
* It enables a simple way to inform readers of the HTML excuses of
whether a rejection is permanent or not. This should hopefully
make it easier for contributors to understand Britney and react
more pro-actively.
