do not blindly assume that all packages stanzas have a "Description:"
field in 'apt-cache show' as well as in the cache creation itself.
We instead assume now that if the stanza has a Description, it will not
be the first field as we look out for "\nDescription" to take care of
MD5sum as well as (maybe ignored) translated Descriptions embedded in
the package stanza.

We do the same in the acquire system which handles the 'normal'
downloads, so do it here as well even though its unlikely anyone
will ever notice (beside testcases of course …)

Testing for global PendingErrors in users of CopyFile is incorrect
in so far as unrelated errors will prevent us from copying perfectly
fine files and checking for the validity of the files is just better
in CopyFiles as it already checks if files are at least opened.
Add also a higher-level error message to the error stack if it fails.

OpenInternDescriptor failures would cause additional errors to be
generated by double-closing an fd. Other errors (although these
are generated if the method is used incorrectly, so unlikely)
didn't close the fd aswell.
Closes: 704608

Previously some errors would set the Fail flag while some didn't
without a clear reason as all errors leave a bad FileFd behind,
so we use a helper now to ensure that all errors set the flag.

Git-Dch: Ignore

In the past packages were flagged "Protected" so that install/
remove markings where issued before the ProblemResolver.
Nowadays, the marking methods check if they are allowed to modify
the marking of a package instead, so that markings set by FromUser
calls are not overwritten anymore by automatic calls which elimates
the need for InstallProtect which just eats CPU now.
The method itself is left untouched for now in case frontend needs it
still for some wierd usecase, but they should be eliminated.

Splits the big loop over dependencies in SmartConfigure which unpacks and
configures dependencies into two loops and reverse their order, so that all
dependencies which need to be unpacked are handled first and only after that
configures are issued for dependencies.
This is needed as otherwise the unpack of a (new) dependency will be issued
in between a configure call for two (or more) packages which form a loop,
which means the configure calls aren't part of the same dpkg call and
therefore dpkg bails out.
Such tight loops should really be avoided as they are usually wrong – and in
reality the dependencies in libreoffice were greatly simplified thanks to
Rene Engelhard so the problem is gone for the benefit of all.

Used to work until a certain (here unnamed) person came along and used
the wrong operator causing low-priority packages to be sorted above
high-priority packages while choosing a provider in commit

Doing Removes early is good to have them out of the way, so they
don't break 'Inst' or 'Conf' chains, but scoring them above Essentials
means that we end up upgrading (many) less important packages before
we handle big stuff like libc6 or debconf which not only fails if those
less important packages have unannounced (strict) dependencies, but also
leads to having these packages unconfigured for a long time triggering
bugs in maintainer scripts for no good reason (#708831).
So this commits sets the default value for remove scores to 100, which
is below the one for essentials (200) and a lot lower than the previous
default value (500).

Some squeeze → wheezy upgrades indicate that DepRemove runs amok
in complicated setups as it wasn't correctly working with or-groups.
Completely rewritten the check is now moving from or-group to or-group
instead.
The behavior should be the same as the code before, but
(hopefully) with less bugs and more comments.

versions to fix partial upgrades (Closes: #707771)
The rename in 0.9.7.9~exp2 moved the method body to the class definition
which means it became inline, which isn't ABI compatibile. The reverse of
moving inline to non-inline is safe though.

- Do not propagate negative scores from rdepends. Propagating the absolute
value of a negative score may boost obsolete packages and keep them
installed instead of installing their successors. (Closes: #699759)

free to escape all lines (we have no lines in our files which need
to be escaped as these would be invalid fieldnames) and while ExecGPGV
would detect dash-escaped text as invalid (as its not expected in
messages with detached signatures) it would be possible to "comment"
lines in (signed) dsc files which are only parsed but not verified

apt-pkg/deb/deblistparser.cc:
- use OpenMaybeClearSignedFile to be free from detecting and
skipping clearsigning metadata in dsc and Release files
We can't write a "clean" file to disk as not all acquire methods copy
Release files before checking them (e.g. cdrom), so this reverts recombining,
but uses the method we use for dsc files also in the two places we
deal with Release files
