Into 3 categories:
* target suite ("testing")
* primary source suite ("unstable")
* additional source suites ("pu" and "tpu")
This will be useful for implementing logic working with suites without
basing it on the name of the suite.

At the moment, it is just a glorified dict. However, we will
eventually use it to get rid of the hardcoded references to "testing"
etc. all over the code.

1) the update didn't happen for all but the first
2) we don't want a package that fixes a regression in unstable to influence the
reference for another package until it actually migrates, so this updating
is flawed.
Given that only one value is defined ("reference"), it is a better
option to allow the config to be unset when one does not want to have
adt_baseline set to "reference".

Notable omissions are "pending_tests" and "tests_results". This is
omission is due to these (some times) being initialized from the
output of "json.load" (so we cannot assume defaultdict semantics
without manually imported the data into one).

The first case is to avoid a creating a list, which is then converted
to a set only to throw away the list again. Here we can just create
the set right away without a list inbetween.
The second case is "if x in [...]:" is better written as "if x in
{...}:" as sets provides faster "__contains__" (assuming you are on a
"recent enough python3", which britney is).

Arguable, this is not a problem in the code as the failure case
invokes sys.exit. However, this is more future proof as the sys.exit
may be replaced (or we may later catch another exception that is
"recoverable").

- revert most of commit adbe6d5 as checking the version in testing doesn't work
when other packages migrate and cause regressions
- Alternative way of determining if a package is regressing, by comparison to a
reference set. The reference set is to be created by a holy trigger that
doesn't take packages from the base suite, but instead tests in the testing
suite. This reference needs a retry when a package causing regression
migrates nevertheless, e.g. due to hints or to bounty/penalty policy.
This commit rewrites the make-shift "log" methods to use the logging
framework without requiring changes to the callers. This will be done
in a latter commit to keep things reviewable.

The other item includes bug numbers so this one is less useful.

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

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.

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.
