apt_preferences and deb822-style sources used the specialized class
pkgUserTagSection to deal with comments before/after a given stanza, but
it couldn't deal with comments in the stanza at all.
codesearch suggests that nobody else does and a vastely superior way of
working with potentially commented files is implemented now, so we can
officially discourage the use of the old incomplete hack class.

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

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.

And of course, testing obscure things ends up showing obscure 'bugs' or
better shortcomings/inconsitencies, so lets fix them with the tests.

xz has pretty much won "the compressor war" and e.g. the Debian archive
doesn't even distribute bz2 anymore in favor of 'xz' and 'gz', so by
changing the default order we have a more realistic --print-uris
behavior as it will always show the first compressor.
In practice this effects repositories without a Release file (very bad,
we don't want to support them anymore anyhow) as xz will be tried before
bz2 now [which is probably not available, but so might be bz2…] AND
repositories which provide both, bz2 and xz (which isn't too common) in
sofar as apt will now download xz instead of bz2.
Users with special needs can stick with bz2 as first compressor tried
with Acquire::CompressionTypes::Order:: "bz2"; (see man apt.conf) – but
users with special needs usually prefer "gz" anyhow, so the realworld
change is expected to be very low.

Also support vertical tabs, as isspace() does the same.

Having two different formats in the same file is very dirty and causes
external tools to fail hard trying to parse them. It is probably not a
good idea for them to parse them in the first place, but they do and we
shouldn't break them if there is a better way.
So we solve this issue for now by giving our deb822 format a new
filename extension ".sources" which unsupporting applications are likely
to ignore an can begin gradually moving forward rather than waiting for
the unknown applications to catch up.
Currently and for the forseeable future apt is going to support both
with the same feature set as documented in the manpage, with the
longtime plan of adopting the 'new' format as default, but that is a
long way to go and might get going more from having an easier time
setting options than from us pushing it explicitely.

Having every item having its own code to verify the file(s) it handles
is an errorprune process and easy to break, especially if items move
through various stages (download, uncompress, patching, …). With a giant
rework we centralize (most of) the verification to have a better
enforcement rate and (hopefully) less chance for bugs, but it breaks the
ABI bigtime in exchange – and as we break it anyway, it is broken even
harder.
It shouldn't effect most frontends as they don't deal with the acquire
system at all or implement their own items, but some do and will need to
be patched (might be an opportunity to use apt on-board material).
The theory is simple: Items implement methods to decide if hashes need to
be checked (in this stage) and to return the expected hashes for this
item (in this stage). The verification itself is done in worker message
passing which has the benefit that a hashsum error is now a proper error
for the acquire system rather than a Done() which is later revised to a
Failed().

It is not very extensible to have the supported Hashes hardcoded
everywhere and especially if it is part of virtual method names.
It is also possible that a method does not support the 'best' hash
(yet), so we might end up not being able to verify a file even though we
have a common subset of supported hashes. And those are just two of the
cases in which it is handy to have a more dynamic selection.
The downside is that this is a MAJOR API break, but the HashStringList
has a string constructor for compatibility, so with a bit of luck the
few frontends playing with the acquire system directly are okay.
