britney assumes that a package build is uniquely described by its
name, version and architecture. Particularly when constructing
Packages files by hand for testing purposes this assumption can be
violated, leading to confusing behaviour. This change makes britney
look for such mismatches, and report if any are found.
In some scenarios, it was possible to trigger a bug in the
installability tester, where it would fail to update the "choices" set.
The requirements for triggering this seems to be something like:
* Obtain a choice that is possible to solve.
* Resolve the choice without recursing (with a backtrack point)
* Obtain a second choice that is impossible to solve.
After the two first steps, the installability tester would fail to
update the "choices" set (or, rather, changes would be invisible to
the "_pick_choice" function). Fortunately, most packages are either
trivially installable or trivially uninstallable, so the bug seems to
be rather rare if triggred at all.

Notably:
* Avoid repeated calls frozenset(X), where we can trivially do
without.
* Skip the inner loop, when "i" is in "to_skip".
* Use a set rather than a list for "to_skip" as we do more
membership tests.

The get_dependency_solvers method returns a (boolean, list)-tuple, but
the boolean can always be implied from the list (in boolean context).

cmp is gone in python3. Also add a sorting method to Excuse that is
compatible with its __eq__/__hash__ methods.

It doesn't exist in python3, but 1000 days should be safe enough as a
fallback for a package without urgency.

- split the one-liner into a for and an if
- use open() as a context manager
- don't use string.strip which is gone in python3

Done as kFreeBSD is not a release architecture and it has started to
block migration of release related changes. I have kept it out of
"BREAK_ARCHES" as I do not yet see a reason to add it there.

The "remark" hint is only intended for showing up in the output of "d"
(or via hint grep). It has no effect on Britney's behaviour.
Admittedly, the original code would have ignored it as well. But this
change makes it explicit and not simply a "ignored due to insufficient
permissions".

For out-of-date binaries, generate different excuses when the build is
missing, or when old (cruft) binaries for previous version are still around.

No longer necessary during the freeze, since they'll need an unblock
anyway, at which point age can be adjusted as well if necessary.
This reverts commit 6891fa39f6.

As agreed in the Jessie timetable, mandatory 10-day
ageing is in place for the freeze, starting today.

As part of a migration, we remove all the existing binaries built by
the source (possibly on a particular architecture) from testing; this
includes architecture-independent binary packages. However, when a
binNMU is in *pu, only the arch-dependent binary pakcages are present.
As a result, after the migration the architecture-independent packages
are no longer present in testing. This usually isn't a practical
problem, as dak will re-add them when it generates the packages files.
It is, however, wrong and will break if a source migration is tempted
during the same run as (and after) the *pu binary migration happened.
The simple fix is to not remove the architecture-independent packages
when performing such migrations.

In the rare case that a hint removed an uninstallable binary, the
binary could still be included in the nuninst counter.
