The update of gcc to gcc-9 introduced a regression in buildability of
anything relying on kernel headers. This could have been caught by the
kernel's standard rebuild autopkgtest, but we currently only trigger the
linux autopkgtest for source packages named gcc-N, which excludes
gcc-defaults.
Include gcc-defaults in the list of packages that trigger a linux rebuild
test.

The intialise method is already complex enough and this was a trivial
snippet to extract to reduce the complexity a bit.

When we convert legacy results in the autopkgtest-results.cache file,
we are only touching leaf results. By moving the loops into a
function, we can remove 2-3 levels of ("redundant") nesting. This in
turn makes it more clear what is relevant in the conversion.
This same also holds in save_state when we convert an Enum to a
string.

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.

apply_src_policy expects an excuse with a new source and binaries. It doesn't
apply to srcarch excuses, which only have new binaries for an existing source.

Currently autopkgtest tries to install our trigger from unstable and the rest
from testing. If that fails, than autopkgtest has a fall-back to allow all
packages from unstable to be installed. This has two severe issues:
1) the version of the test and the package it came from may be out-of-sync
2) too much from unstable may be installed, even stuff that should not/is not
allowed to migrate as it breaks stuff.
Make sure that test depends also get added to triggers if they are broken.
E.g. imagine the following scenario: trigger X changes (breaks) the output
generated by Y. Package Z has Y in the test dependencies and compares the
output in the autopkgtest. We want to have the opportunity that a new version
is automatically fixing the situation.
Two use cases are currently unsupported: needs-build (autopkgtest restriction)
and test dependencies generated by autodep8.
In case autopkgtest triggering is delayed because the required builds aren't
ready yet or the package is not installable, currently there is only the
message that autopktest delays the migration, but no hint why. This commit adds
these hints.
The initial idea was to do this to bootstrap the baseline, but it turns out
that this has the drawback it triggers runs for a package that has a new
autopkgtest where it didn't have it in the version in the target suite. It was
considered harmless (as it would just have a failing reference), but due to
autodep8, package can have a passing result in the target suite while the new
autopkgtest is actually broken. Such a package should not be blocked / getting
a penalty.
The alternative is to make the check here smarter, but as this is only for
bootstrapping, lets do that outside of britney proper.
When determining whether a policy applies to a given item, use the
suite class rather than the suite name.

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.
