We changed an aweful lot of stuff, so 5.0 is properly better than 4.X as
a semantic version and as we are at it lets add some trivial symbol
versioning as well: We just mark all exported symbols with the same
version for now. This isn't really the proper thing to do as if we add
symbols in later versions (with the same abi) they will get the same
symbols version, but our .symbols file will protect us from the problems
arising from this as it will ensure that a package acutally depends on a
version of the abi high enough to include the symbol.

cxx11abi transition happens, we changed a bunch of methods and all that
stuff which is really good™ for an abi. Lets just slowly start to stop
changing more and a first step is to document the current so changes
aren't hidding in a big wall of change anymore.

The library(s) make an API break anyhow, so lets ensure we use gcc5 for
this break and enable c++11 as standard as gcc6 will use it as default
and should provide some API parts for c++11 – beside that it can't hurt
to use c++11 itself. We just have to keep our headers c++03 compatible
to not enforce a standrd bump in our reverse dependencies.

If all keyrings are simple keyrings we can merge the keyrings with cat
rather than doing a detour over gpg --export | --import (see #790665),
which means 'apt-key verify' can do without gpg and just use gpgv as
before the merging change.
We declare this gpgv usage explicit now in the dependencies. This isn't
a new dependency as gnupg as well as debian-archive-keyring depend on
and we used it before unconditionally, just that we didn't declare it.
The handling of the merged keyring needs to be slightly different as our
merged keyring can end up containing the same key multiple times, but at
least currently gpg does remove only the first occurrence with
--delete-keys, so we move the handling to a if one is gone, all are gone
rather than an (implicit) quid pro quo or even no effect.
Thanks: Daniel Kahn Gillmor for the suggestion

dpkg and dak know various field names and order them in their output,
while we have yet another order and have to play catch up with them as
we are sitting between chairs here and neither order is ideal for us,
too.
A little testcase is from now on supposed to help ensureing that we do
not derivate to far away from which fields dpkg knows and orders.

The rational is that https downloads fail with cryptic error messages
if the certificates are missing.

The current filtering matches the names of the image metapackages on the
i386 architecture:
$ dpkg-query -l | awk '/^ii[ ]+(linux|kfreebsd|gnumach)-image-[0-9]/ && $2 !~ /-dbg$/ { print $2 }'
linux-image-3.16.0-4-586
linux-image-586
This results in an extra image package being removed from
APT::NeverAutoRemove, losing the intended effect of keeping the {current,
previous, latest} set of images installed.
Requiring a “.” in the package name tightens the matched package names
to those that are installing a specific version of the image, thus
eliding the meta-packages.

Collect all hashes we can get from the source record and put them into a
HashStringList so that 'apt-get source' can use it instead of using
always the MD5sum.
We therefore also deprecate the MD5 struct member in favor of the list.
While at it, the parsing of the Files is enhanced so that records which
miss "Files" (aka MD5 checksums) are still searched for other checksums
as they include just as much data, just not with a nice and catchy name.
This is a cherry-pick of 1262d35 with some dirty tricks to preserve ABI.

APT supports more than just one HashString and even allows to enforce
the usage of a specific hash. This class is intended to help with
storage and passing around of the HashStrings.
The cherry-pick here the un-const-ification of HashType() compared to
f4c3850ea335545e297504941dc8c7a8f1c83358. The point of this commit is
adding infrastructure for the next one. All by itself, it just adds new
symbols.

By convention, if I run a tool with --help or --version I expect it to
exit successfully with the usage, while if I do call it wrong (like
without any parameters) I expect the usage message shown with a non-zero
exit.

We have a d-pointer available here, so go ahead and use it which also
helps in hidding some dirty details here. The "hard" part is keeping the
abi for the inlined methods so that they don't break – at least not more
than before as much of the point beside a speedup is support for more
than 256 fields in a single section.

Adding a new parameter (with a default) is an ABI break, but you can
overload a method, which is "just" an API break for everyone doing
references to this method (aka: nobody).

We have a bunch of classes which are of no use for the outside world,
but were still exported and so needed to preserve ABI/API. Marking them
as hidden to not export them any longer is a big API break in theory,
but in practice nobody is using them – as if they would its a bug.
|
|
We can't add a new virtual method without breaking the ABI, but we can
freely add new methods, so for older ABIs we just implement this method
with a dynamic_cast, so that clients can be more ignorant about the API
here and especially don't need to pull a very dirty trick by assuming
internal knowledge (like apt-get did here).

Ensure in SetupAPTPartialDirectory() that the /etc/apt/auth.conf file
can be read by the priv sep apt methods.
|

If the methods drop privileges we need to ensure that
/etc/apt/apt.conf is still readable by the _apt user.

Using a different user for calling methods is intended to protect us
from methods running amok (via remotely exploited bugs) by limiting what
can be done by them. By using root:root for the final directories and
just have the files in partial writeable by the methods we enhance this
in sofar as a method can't modify already verified data in its parent
directory anymore.
As a side effect, this also clears most of the problems you could have
if the final directories are shared without user-sharing or if these
directories disappear as they are now again root owned and only the
partial directories contain _apt owned files (usually none if apt isn't
running) and the directory itself is autocreated with the right
permissions.

apt-key creates trusted.gpg if it needs it with 644 nowadays, but before
it ensured this, it was gpg creating it, which gives it by default 600.
Not a problem as long as our gpgv is run as root, but now that we drop
privileges we have to ensure that we can also read trusted.gpg files
created by earlier apt-key versions.

Because of dpkg-buildflags we already get most of the hardening
features, +all adds -fPIE and ld -z now

The fileformat of a pdiff index stores currently only SHA1 hashes. With
this change, we look for all other hashes we support as well and take
what we get, so that we can work after the release of jessie to get
right of SHA1 if we want to.
Note that the completely patched file is and was checked against the
hashes collected from the Release file, so this transition isn't mission
critical.
