On single-arch the parsing was creating groupnames like 'apt:amd64' even
through it should be 'apt' and a package in it belonging to architecture
amd64. The result for foreign architectures was as expected: The
dependency isn't satisfiable, but for native architecture it means the
wrong package (ala apt:amd64:amd64) is linked so this is also not
satisfiable, which is very much not expected.
No longer excluding single-arch from this codepath allows the generation
of the correct links, which still link to non-exisiting packages for
foreign dependencies, but natives link to the expected native package
just as if no architecture was given.
For negative arch-specific dependencies ala Conflicts this matter was
worse as apt will believe there isn't a Conflict to resolve, tricking it
into calculating a solution dpkg will refuse.
Architecture specific positive dependencies are rare in jessie – the
only one in amd64 main is foreign –, negative dependencies do not even
exist. Neither class has a native specimen, so no package in jessie is
effected by this bug, but it might be interesting for stretch upgrades.
This also means the regression potential is very low.

Remove long obsolete (hold, hold-reinstreq, removal-failed) or just
wrong (post-inst-failed vs postinst-failed) values, that have been
autoconverted by dpkg at run-time to their new equivalents, so there
should not be any such instance in any recent system (removal-failed
since dpkg 1.1.4 in Apr 1996, hold and hold-reinstreq since dpkg
1.2.0 in May 1996). dpkg even stopped doing the mapping in 1.15.4
and 1.15.8 respectively.
At the same time sort the list in the same order as they appear in
the dpkg code.

APT supported versioned provides for a long while in an attempt to get
it working with rpm. While this support is old, we can be relatively
sure that it works as versioned provides are used internally to make
Multi-Arch:foreign work.
Previous versions of apt will print a warning indicating that the
versioned provides is ignored, so that something which "Provides: foo (=
2)" doesn't provide anything.
Note that dpkg does allow only a equals-relation in the provides line
as anything else is deemed too complex. apt doesn't support anything
else either and such a support would require potentially big changes.

Seems this was missed somehow.
Closes: #759099

A call to UniqFindTagWrite can trigger the need for a bigger mmap, which
is usually done by moving it, but with this move all pointers into it
become invalid (and have to be remapped). The compiler calculates the
pointer before the execution of the call though, so it tries to store
the returned value at the old location, resulting in a segfault.
We solve this by use of a temprorary variable as we did in the other
instances of this problem before.

In #737085 we see that apt can be confused if informations about
versions only differ slightly. This commit adds a way of at least adding
a few more data points with the next abi break to help a bit with it.

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

Inspired by the rest of the patch in 661537, but abstract the
parsing of various ways of setting the build profiles more so it can
potentially be reused and all apt parts have the same behaviour.
Especially config options, cmdline options and environment will not be
combined as proposed as this isn't APTs usual behaviour and dpkg doesn't
do it either, so one overrides the other as it normally does.

Build-dependencies are now able to include a <profile.foo …>
specification limiting usage similar to already supported [arch …].

The parser goes a bit to far by stripping :any from dependencies in a
single architecture environment. the flag "Multi-Arch: allowed" doesn't
care any architecture restrictions in that case (as in single arch
everything is native), but it still limits the possible versions
statisfying the dependency so stripping :any over-simplifies in upgrade
situations from "Multi-Arch: none" to "Multi-Arch: allowed".

Release files are basically one big Section, so we might safe some
Resize circles by starting with the filesize.
Git-Dch: Ignore
|

The handwritten parsing here was mostly done as we couldn't trust the
Release file we got, but nowadays we are sure that the Release file is
valid and contains just a single section we want it to include.
Beside reducing code it also fixes a bug: Fieldnames in deb822 formatted
files are case-insensitive and pkgTagFile does it correctly, but this
selfbuilt stuff here didn't.

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.

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

by introducing a pseudo-architecture 'none' so that the small group of
users with these packages can get right of them without introducing too
much hassle for other users (Closes: #686346)

- negative dependencies need to apply to all architectures,
but those with a specific architecture only apply to this one

- Set the Essential flag on APT instead of only Important

internally so that it is exported and can be used like a "normal"
uncompressed file with FileFd
This allows us to hide th zlib usage in the implementation and use gzip
instead if we don't have zlib builtin (the same for other compressors).
The code includes quiet a few FIXME's so while all tests are working
it shouldn't be used just yet outside of libapt as it might break.
