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.

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 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.

Originally when binNMUs for packages in testing were scheduled, the
binaries would be installed into tpu with no accompanying source. This
allowed the "removed binary" portions of should_upgrade_srcarch() to be
skipped (as britney had generated a faux source record).
dak now adds the source package to tpu in such cases which lead to the
"removed binary" checks being applied to binNMUs in tpu with potentially
destructive consequences. For example, if a package with amd64 and i386
binaries in testing were binNMUed on just amd64, britney would notice
that there were no i386 binaries in tpu and subsequently remove the i386
binaries from testing as well.
In order to resolve this, we skip the check for removed binaries when
building excuses for a binary-only migration via *pu.

The primary difference between the parsing / output of excuses for *pu
and unstable unblocks is the messages displayed. We can therefore remove
some duplication by having the same code handle both, outputting the
appropriate message.
Where a *pu package is also the subject of a "block" (most likely during
a freeze) we only supply the "needs approval" or "approved" message;
previously both "needs approval" and "not touching due to block" were
output, which is redundant. We ensure that there is always a dummy
"block" hint for *pu packages to provide the "needs approval" behaviour.

Commit 94071b1649 excluded intra-source
dependencies from the determination as to whether a binary package was

are situations where it breaks migration. For instance:
foo depends on libdropped1
libdropped1 depends on libdropped2
libdropped1 and libdropped2 are built from the same source; foo from
another source
libdropped2 is otherwise leaf in testing
In order to resolve this, we build a list of all packages which might
be eligible and filter out those which have reverse-dependencies outside
of their source package. For each remaining package, we consider it
eligible if its intra-source reverse-dependencies are within the list
of packages already determined to be eligible.

get_full_tree may be passed an initial package which does not exist in the

If the package was previously arch:all and uninstallable and has moved to
being architecture-dependent, becoming installable in the process, then it
will not be in the architecture-dependent uninstallability set; we
therefore should try removing it from that set.
When marking the reverse dependencies of each binary package as affected
by a sourceful update to testing, the reverse dependencies of those
packages are also affected, and so on.
This helps to avoid situations where the installability of immediate
reverse dependencies is unchanged, but that of other packages in the
