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For out-of-date binaries, generate different excuses when the build is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.

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.

sort_actions() can be quite expensive and it is wasteful to resort
actions after each successful "easy"-hint.

There are no uses of "lundo" left for a non-hint recurse run (i.e.
the "main run"), so there is no point in building it.
The "lundo"-list is still used in the recurse run of a "hint"-hint.

The "do_all"-method now checks the architectures of all changes
applied. If they entirely consist of items from "break archs", then
"do_all" will disregard the current "break archs" setting when
comparing nuninst counters.
This change avoids unintended installability regressions on break
arches when a hint (manual or automatic) apply only to packages on
break arches.

Rename local variables and avoid repeated chained lookups. In
particular, avoid confusing cases like:
[...]
version = binaries[parch][0][binary][VERSION]
[...]
binaries[parch][0][binary] = self.binaries[item.suite][parch][0][binary]
version = binaries[parch][0][binary][VERSION]
Where "version" here will refer to two different versions. The former
the version from testing of a hijacked binary and the latter the
version from the source suite (despite the look up using the "testing"
table, due to the testing copy being updated).
Notable renamings:
* binaries => packages_t (a.k.a. self.binaries['testing'])
* binaries[parch][0] => binaries_t_a
* binaries[parch][1] => provides_t_a
* Similar naming used for "item.suite" instead of "testing"
The naming is based on the following logic:
* self.binaries from "packages" files
(by this logic, it ought to be "self.packages", but that is
for later)
* The "_X_a" is short for "[<suite>][<parch>]" look ups.
* binaries_X_a and provides_X_a are the specialised parts of
packages_X_a that deal with (real) binary packages and
provides (i.e. virtual packages) respectively.

When trying to break a choice, try the candidate out and see if we can
pick it without any consequences. Basically, if the candidate causes
no new conflicts or choices, we can safely pick it.

For some cases, like aspell-dictionary, a number of packages can
satisfy the dependency (e.g. all aspell-*). In the particular
example, most (all?) of the aspell-* look so similar to the extent
that reverse dependencies cannot tell two aspell-* packages apart (IRT
to installability and co-installability).
This patch attempts to help the installability tester by detecting
such cases and reducing the number of candidates for a given choice.

Extract a specialised iter_packages_hint from iter_packages that only
deals with applying hints. This simplifies iter_packages AND avoids
having to re-compute the uninstallability counters after each single
item in the hint.
This means that a hint can now avoid triggering expontential runtime
provided only that the "post-hint" stage does not trigger expontential
runtime. Previously the hint had to be ordered such that none of the
items in the hint caused such behaviour (if at all possible).

Avoid creating two dependency clauses for dependencies emulating a
"version range" a la:
Depends: pkg-a (>= 2), pkg-a (<< 3~)
Previously this would create two clauses a la:
- (pkg-a, 2, arch), (pkg-a, 3, arch)
- (pkg-a, 1, arch), (pkg-a, 2, arch)
However, it is plain to see that only (pkg-a, 2, arch) is a valid
solution and the other options are just noise. This patch makes
Britney merge these two claues into a single clause containing exactly
(pkg-a, 2, arch).

The "new" auto hinter relies on partial ordering to determine, when
what can migrate (and what needs to migrate at the same time). At the
same time, it leverages on "_compute_groups" to allow it to include
"removals" in its hints.

Avoid smooth-updating libraries in hints, when all of their reverse
dependencies will certainly disappear in the same hint.
Note that in "hint"-hint, reverse dependencies removed in the
following "full run" will not cause the smooth-updated library to be
removed. Instead these will still be removed in the end as usual, but
in some cases that is too late.

Rename find_upgraded_binaries into _compute_groups. The new method
will also compute what binaries will be updated in or added to testing
after migration.
