This adds ::InfoFD option alongside the ::Version one to request sending
the information to the specified FD, by default it is STDIN as it was
the case before.
The environment variable APT_HOOK_INFO_FD contains the FD the data is on as
a confirmation that the APT version used understood the request.
Allowing the hook to choose the FD is needed/helpful e.g. for shellscripts
which have a hard time accessing FDs above 9 (as >= 10 are usually used
internally by them)

Release files are basically one big Section, so we might safe some
Resize circles by starting with the filesize.

While we don't want these error messages on our usual stack, we can use
our usual infrastructure to generate an error message with all the usual
bells like errno and strerror attached.

If this code is run as non-root we are in a special situation (e.g. in
our testcases) where it is obvious that we can't enforce user/group on
any file, so skip this code altogether instead of bugging users with
an error message – which we also switch to a warning as a failure to
open the file is "just" a warning, so the 'wrong' owner shouldn't be
that much of an issue.
The file is still handled with chmod, so all the security we can enforce
is still enforced of course, which also gets a warning if it fails.

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.

The code incorrectly skips printing of current version information,
if the package has no current version (for APT, but for dpkg as it is
the case for packages which are removed but not purged) by using an
unintended "else if" rather than an "if".

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**

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

before, but later code can be sure about the format
