This makes it easier to see which headers includes what.

The changes were done by running

    git grep -l '#\s*include'  \
        | grep -E '.(cc|h)$' \
        | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/'

To modify all include lines by adding a space, and then running
./git-clang-format.sh.

This gives the repository owner a chance to explain why this change was
needed – e.g. explaining the organisational changes or simply detailing
the changes in the new release made. Note that this URI is also shown
if the change is accepted, so it also draws attention to release notes
of minor updates (if users watch apt output closely).

The value of Origin, Label, Codename and co can be used in user
configuration from apts own pinning to unattended upgrades.
A repository changing this values can therefore have serious effects on
the behaviour of apt and other tools using these values.

In a first step we will generate error messages for these changes now
explaining the need for explicit confirmation and provide config options
and commandline flags to accept them.

If we couldn't find an entry for a Sources file we would generate an
error while for a Packages file we would silently skip it due to
assuming it is missing because it is empty. We can do better by checking
if the repository declares that it supports a component we want to get
the file from and if not say so and hint at the user making a typo.

An example were this helps is mozilla.debian.net which dropped the
firefox-aurora component (as upstream did) meaning no upgrades until the
user notices manually that the repository doesn't provide packages
anymore. With this commit warnings are raised hopefully causing the user
to investigate what is wrong (sooner).

<title>don't warn if untransformed distribution matches</title>

A suite or codename entry in the Release file is checked against the
distribution field in the sources.list entry that lead to the download of that
Release file. This distribution entry can contain slashes in the distribution
field:

    deb http://security.debian.org/debian wheezy/updates main

However, the Release file may only contain "wheezy" in the Codename field and
not "wheezy/updates". So a transformation needs to take place that removes the
last / and everything that comes after (e.g. "/updates"). This fails, however,
for valid cases like a reprepro snapshot where the given Codename contains
slashes but is perfectly fine and doesn't need to be transformed. Since that
transformation is essentially just a workaround for special cases like the
security repository, it should be checked if the literal Codename without any
transformations happened is valid and only if isn't the dist should be checked
against the transformated one.

This way special cases like security.debian.org are handled and reprepro
snapshots work too.

The initial patch was taken as insperationto move whole transformation
to CheckDist() which makes this method more accepting &amp; easier to use
(but according to codesearch.d.n we are the only users anyhow).

Thanks: Lukas Anzinger for initial patch

<title>allow repositories to forbid arch:all for specific index targets</title>

Debian has a Packages file for arch:all already, but the arch:any files
contain arch:all packages as well, so downloading it would be a total
waste of resources. Getting this solved is on the list of things to do,
but it is also the hardest part – for index targets like Contents the
situation is much easier and less server/client implementations are
involved so we might not want to stall them.

A repository can now declare via:
No-Support-for-Architecture-all: Packages
that even if an arch:all Packages exists, it shouldn't be downloaded, so
that support for Contents files can be added now.

See also 1dd20368486820efb6ef4476ad739e967174bec4 for the implementation
of downloading arch:all index targets, which this is limiting.

The field uses the name of the target from the apt configuration for
simplicity and is negative by design as this field is intended to be
supported/needed only for a "short" time (one or two Debian releases).

While this commit theoretically supports any target, its expected to
only see "Packages" as a value in reality.

<title>support arch:all data e.g. in separate Packages file</title>

<id>urn:sha1:1dd20368486820efb6ef4476ad739e967174bec4</id>

Based on a discussion with Niels Thykier who asked for Contents-all this
implements apt trying for all architecture dependent files to get a file
for the architecture all, which is treated internally now as an official
architecture which is always around (like native). This way arch:all
data can be shared instead of duplicated for each architecture requiring
the user to download the same information again and again.

There is one problem however: In Debian there is already a binary-all/
Packages file, but the binary-any files still include arch:all packages,
so that downloading this file now would be a waste of time, bandwidth
and diskspace. We therefore need a way to decide if it makes sense to
download the all file for Packages in Debian or not. The obvious answer
would be a special flag in the Release file indicating this, which would
need to default to 'no' and every reasonable repository would override
it to 'yes' in a few years time, but the flag would be there "forever".

Looking closer at a Release file we see the field "Architectures", which
doesn't include 'all' at the moment. With the idea outlined above that
'all' is a "proper" architecture now, we interpret this field as being
authoritative in declaring which architectures are supported by this
repository. If it says 'all', apt will try to get all, if not it will be
skipped. This gives us another interesting feature: If I configure a
source to download armel and mips, but it declares it supports only
armel apt will now print a notice saying as much. Previously this was a
very cryptic failure. If on the other hand the repository supports mips,
too, but for some reason doesn't ship mips packages at the moment, this
'missing' file is silently ignored (= that is the same as the repository
including an empty file).

The Architectures field isn't mandatory through, so if it isn't there,
we assume that every architecture is supported by this repository, which
skips the arch:all if not listed in the release file.
