Traditionally all providers are protected providing something as apt
can't know which of them is actually really providing the functionality
for the user ensuring that we don't propose the removal of used stuff,
but that is of course also keeping stuff around which could be removed.
That can cause the collection of multiple old providers until the
provided package is itself no longer needed (e.g. out-of-tree kernel
modules). We combat this by marking providers only from the newest
source package version so that old providers built by older versions of
the same source package can be garbage collected.

This doesn't allow all tests to run cleanly, but it at least allows to
write tests which could run successfully in such environments.

The bugreport is more conservative in asking for a conditional, but
given that this is a message intended to be read by users to be run by
users we should suggest using a command intended to be used by users.
And while we are at, add sudo to the message – conditional of course.

In private-install.cc we call MarkInstall with FromUser=true, which sets
the bit accordingly, but while applying the EDSP solution we call mark
install on all packages with FromUser=false, so MarkInstall believes
this install is an automatic one and sets it to auto – so that a new package
which is explicitely installed via an external solver is marked as auto
and is hence also up for garbage collection in a following call.
Ideally MarkInstall wouldn't reset it, but the detection is hard to do
without regressing in other cases – and ideally ideally MarkInstall
wouldn't deal with the autobit at all – so we work around this on the
calling side for now.

apt-get is displaying various lists of package names, which until now it
was building as a string before passing it to ShowList, which inserted
linebreaks at fitting points and showed a title if needed, but it never
really understood what it was working with. With the help of C++11 the
new generic knows not only what it works with, but generates the list on
the fly rather than asking for it and potentially discarding parts of
the input (= the non-default verbose display). It also doubles as a test
for how usable the CacheSets are with C++11.
(Not all callers are adapted yet.)

We use test{success,failure} now all over the place in the framework, so
its only consequencial to do this in the situations in which we test for
a specific output as well.

We can't remove packages which are held back by the user with a hold, so
marking them (or its dependencies) as garbage will lead our autoremover
into madness – and given that the package is important enough that the
user has held it back it can't be garbage (at least at the moment), so
even if a front-end wants to use the info just for information display
its a good idea to not consider it garbage for them.

For many commands the output isn't stable (like then dpkg is called) but
the exitcode is, so this helper enhances the common && msgpass ||
msgfail by generating automatically a msgtest and showing the output of
the command in case of failure instead of discarding it unconditionally,
the later being chronic-like behaviour
