Multi-Arch: same packages can be co-installed, but need to have the same
version for all installed packages (aka "siblings"). Otherwise the
unsynced versions will fight against each other and the auto-install as
wel as the problem resolver will later have to decide between holding the
packages or to remove one of the siblings (usually a foreign) taking a
bunch of packages (like the entire foreign setup) with them.
The idea here is now to be more pro-active: MarkInstall will fail for
a package if the siblings aren't synced, so we don't allow a situation
in which a resolver has to decide if to hold or to remove-upgrade under
the assumption that the remove-upgrade decision is always wrong and
doesn't deserve to be explored (expect valid out-of-syncs of course).
Thats a pretty bold move to take for a library which is used by
different solvers so this check is done in IsInstallOk and can be
overridden if front-ends want to.

Default is to acquire all architectures from APT::Architectures which
can be changed by arch=, but this isn't very flexible if you want
"mostly" the default as you have to hardcode the architectures then,
so arch-= and arch+= can be used to add/remove architectures from the
default set.
On a machine with 'amd64' and 'i386' configured the lines:
deb [arch+=armel] http://example.org/debian wheezy rocks
deb [arch-=amd64] http://example.org/debian jessie rocks
will result in the download of:
wheezy Packages for 'amd64', 'i386' and 'armel'
jessie Packages for 'i386'

Adds on top of Version 2 to all displayed version numbers the
architecture as well as the MultiArch flag for consumption by the hooks.
Most of the time the architecture will be the same for both versions
displayed, but packages might change from "all" to "any" (or back)
between versions so we can't display the architecture for packages.
Pseudo-Format for Version 3:
<name> <version> <arch> <m-a-flag> <compare> <version> <arch> <m-a-flag>
Examples:
stuff - - none < 1 amd64 none **CONFIGURE**
libsame 1 i386 same < 2 i386 same **CONFIGURE**
stuff 2 i386 none > 1 i386 none **CONFIGURE**
libsame 2 i386 same > - - none **REMOVE**
toolkit 1 all foreign > - - none **REMOVE**

GCC 4.8 is now clever enough to warn about:
contrib/sha2_internal.cc: In function ‘char* SHA256_End(SHA256_CTX*, char*)’:
contrib/sha2_internal.cc:656:31: warning: argument to ‘sizeof’ in ‘void*
memset(void*, int, size_t)’ call is the same expression as the destination;
did you mean to dereference it? [-Wsizeof-pointer-memaccess]
MEMSET_BZERO(context, sizeof(context));
So fix it as suggested. Its interesting though that the SHA2*
calculation as far as we need it works even without zeroing out.

fixup for 42d51f333e8ef522fed02cdfc48663488d56c3a3
The for-loop iterating over the DepIterators which need configuration
can (and will be in 'complicated' situations) run multiple times, so we
can't just GlobOr on the DepIterator as it modifies it, so that the next
iteration over the list ends up checking another dependency leading us
into a 'Internal error, packages left unconfigured. foopkg' maybe or we
are 'lucky' and calculate a solution which might break down the line

With the selfgrown splitting we got the problem of not recovering
from networks which just reply with invalid data like those sending
us login pages to authenticate with the network (e.g. hotels) back.
The good thing about the InRelease file is that we know that it must
be clearsigned (a Release file might or might not have a detached sig)
so if we get a file but are unable to split it something is seriously
wrong, so there is not much point in trying further.
The Acquire system already looks out for a NODATA error from gpgv,
so this adds a new error message sent to the acquire system in case
the splitting we do now ourselves failed including this magic word.
Closes: #712486

Before we download the 'new' InRelease file the old file will be moved
out of the way with the name 'foobar_InRelease.reverify', so if no
partial file for the 'new' file exists take the modification time from
this reverify file, so that if we get an IMS hit for the InRelease file
we can move back the reverify file as new file rather than downloading
the 'new' file even though we already have it.
We do the same for Release files and this happened to work until the
reverify renaming was corrected for InRelease files.

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.
Closes: #712435

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.

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.
