For (non-hint) migrations, split the set of affected into two
parts; one for reverse dependencies and one "negative dependencies"
(e.g. Conflicts).
If there are only regressions in the nuninst after checking the first

"negative dependencies" can only make it worse at that point).

Ideally we would reject all items with known unsatisfiable

In an architecture only migration, we currently see two notes for
every arch:all packages:
* Ignoring "new" arch:all package
* Ignoring "removal" of arch:all package
But a closer look at the situation is that the arch:all packages is
generally the same in both testing and the source suite.
This commit removes these notes when the arch:all is the same in both

There was an implicit assumption in Britney that was violated recently
(presumbly in 12d9ae8). This assumption is that a source package will
reference the *latest* version of an arch:all package; even if that
version is not built by that source (version).
Image the following packages:
* p-all/1 and p-all/2 are arch:all packages.
- p-all/1 is generally superseded by p-all/2 except it has not
been removed yet (regardless of why that happens).
* src-a/2 builds p-all/2.
When Britney loads the packages (assuming packages are sorted[1]):
* p-all/1 is read and associated with src-a/2 (despite not being
built from that source)
* p-all/2 is read afterwards. It would replace p-all/1 and be
assoicated with src-a/2 as well.
- Prior to 12d9ae8, the assoication would be "pkg, arch" and
therefore the same.
- In 12d9ae8a and after, the association would include version
and both would be associated at the same time.
* Since p-all/1 is discarded, it is never added to the
installability tester (nor the solver). It then promptly throws
an exception when asked to deal with a package it believe does
not exist.
- This can trivially be solved by removing the association
between p-all/1 and src-a/2 when p-all/2 is read.
So far so good. Unfortunately, this adds another another problem!
When Britney migrates a binNMU, she currently removes *all* binary
packages on that architecture - *including* the arch:all packages.
This works out in the end because the arch:all packages be re-added
since they associated with the source package.
At first glance, this appears to be a non-issue until you add
hijacking to the mix. This is *exactly* the case behind #709460.
However, now we end up in a situation where the arch:all package is
removed during binNMU and not re-added (because the arch:all package
is not associated with *that* source any more).
This commit fixes all of the above by:
1) Correctly disassociating superseded arch:all packages from their
source packages
2) Falsely associating the "new" arch:all package to the source that
provided the superseded arch:all package (to avoid issues with
binNMUs and hijacked packages).
- This should probably be undone at some point when Britney does
not need this "hack" any more.
This fix is currently relying on the packages being sorted. But so
did the fix for #709460 (see [1] again). It might be prudent to fix
that as well (or at least reject the packages file rather than produce
"random" results).
[1] Which is another assumption we have been relying and that is
currently satisfied.

The same_source is supposed to compare two versions and (if needed)
"massage" a binNMU version into a source version. This extra feature
of same_source happens to be unused (and not generally applicable):
1) We always compare two source versions, so there is never a
binNMU version in the first place.
2) binary versions are *not* always equal to their source version
(even with the binNMU suffix stripped). This happens when
packages use "dpkg-gencontrol -v<version>".
Note this causes results from some live-data tests to change, because
there has been a sourceful upload with a binNMU version. It was
intended as a binNMU, but was uploaded with the source as well. As
Britney no longer works around this issue, it makes her remove the
affected packages in the end (as their source version does not match
the version in testing).

This bug involves a corner case that involves:
* source orig providing liborig1 and orig-doc in testing
* source orig providing liborig2 and orig-doc in unstable
* source hijack providing liborig2 and orig-doc in both testing and unstable,
where the versions of hijack's binaries has a higher version than those of
"orig".
The arch:all packages are needed to trigger this, because Britney
flags an arch:any package as "out of date" and stops the migration
there. However, she is more lenient with arch:all packages.
What happens is that Britney realises that src:orig need to be updated
in testing (to remove liborig1). This leaves src:orig with no
binaries left in testing (as the orig-doc from hijack is used) and it
is therefore removed as an obsolete source. The obsolete removal then
exploded because Britney was also trying to remove the liborig1
package, which is no longer there.

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.

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.

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.

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.

Presumably there once was a reason for having a notion of "depth",
but these days only 3 "values" were given as "maxdepth":
* "easy" (for easy hint)
* 0 (for "main run" or in a "hint"-hint)
* -1 (for force-hint)

This allows britney to load a python2.7 variant of the C module when
run under python2.7.
Note for python3, we add "python3" rather than "python3.Y". This is
to reflect the include path in the python3 package in the archive.
