In excuse_unsat_deps(), mark unsatisfiable dependencies not just in the HTML,
but also in the invalid_deps list. If we have any of those in
should_upgrade_src(), block the package and don't run the autopkgtest. This
avoid running tests for known-uninstallable packages, which just leads to
guaranteed failures, manual intervention of re-running tests after it becomes
installable, and spamming maintainers with a FAIL/PASS notification.
This reproduces the failure to hold back gccgo-4.9 due to the broken libgcc1
package. This only seems to happen when a new source package takes over an
existing binary package.
This currently checks that an autopkgtest is triggered for an installable
package, and that no autopkgtest is triggered for an uninstallable one
(failing, demonstrating a bug).
Based on Colin Watson's code to do the same from the "britney2-ubuntu"
repository[1] revision 306, 308 and 309.
Notable differences include:
* output include version of source package being removed
* output prefix removals with a "-" (otherwise it would be identical to
a upgrade/new source with the change above).

This introduces a new variable HINTSDIR, which overrides the location of the
Hints dir (normally it is read from the UNSTABLE dir).
Please note that this is the location of the dir that contains the Hints dir.

This introduces a new variable OUTPUTDIR, which overrides the location where
the new dates file is written. This allow to run britney against a read-only
copy of the data.

If an architecture is marked as fucked, britney's package list for that
architecture may include arch:all packages for an older version. When
outputting the result file, we should not include those packages as
they will lead to import failures.

The new Installability Tester (IT) module replaces the remaining
C-parts. Unlike C-implementation, it does not give up and emit an
"AIEEE" half-way through.
In order to determine installability, it uses two sets "musts" and
"never". As the names suggest, the sets represents the packages that
must be (co-)installable with the package being tested and those that
can never be co-installable. For a package to be installable, "musts"
and "never" have remain disjoint.
These sets are also used to reduce the number of alternatives that are
available to satisfy a given dependency. When these sets are unable
to remove the choice completely, the new IT defers the choice to later.
This occasionally reduces backtracking as a later package may conflict
or unconditionally depend on one of the remaining alternatives.
