parse debian/tests/control for test dependencies

Our integration tests need some additional dependencies to run and
function correctly, but while multiple places run them, there is no need
to also specify the these dependencies in multiple places.

Git-Dch: Ignore
ensure that all docs use all entities files

Not all are needed for all files at the moment, but the new docbook
building hadn't available some of the entities it used as the files
weren't correctly copied around in all cases and having the same across
the bord makes working with all of them a little easier.

Git-Dch: Ignore
remove obsolete documentation bits

Git-Dch: Ignore
rewrite and extend new README file

Reuse description from the package descriptions and add various
subsection describing useful debug options and general information.

Turkish program translation update

Closes: 756710
Czech program translation update

Closes: 758208
add dpkg::source-options for dpkg-source invocation

dpkg-source can be told to enforce signature checks with
--require-valid-signature, but while this isn't feasible as default for
Debian itself at the moment, a local admin should be able to use it.

This commit also fixes the size limit on the construction of the command
being called for dpkg-source and dpkg-buildpackage.

Closes: 757534
support versioned provides as implemented by dpkg

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.

prepare 1.0.7

German program translation update

Closes: 758837
The following command otherwise yields many blank lines:
apt list -o APT::Cmd::use-format=true -o APT::Cmd::format=\${Package}

And even worse when adding "-o APT::Cmd::All-Versions=true".

Portuguese manpages translation update

Closes: 759608
initialize iPolicyBrokenCount in DepCache::Update

All other counters are correctly initialized here, expect this one. The
practical effect is low as in apt we usually just do "!= 0" checks, but
only correct counters are good counters.

Closes: 758397
Make Proxy-Auto-Detect check for each host

When doing Acquire::http{,s}::Proxy-Auto-Detect, run the auto-detect
command for each host instead of only once. This should make using
"proxy" from libproxy-tools feasible which can then be used for PAC
style or other proxy configurations.

Avoid yielding blank lines with APT::Cmd::use-format=true

* apt-pkg/deb/dpkgpm.cc:
    - update string matching for dpkg I/O errors. (LP: #1363257)
    - properly parse the dpkg status line so that package name is properly set
      and an apport report is created. Thanks to Anders Kaseorg for the patch.

Use heap to allocate PatternMatch to avoid potential stack overflow

When apt-cache search with many args (> 130) is given the allocation
of PatternMatch on the stack may fail resulting in a segmentation
fault. By using the heap the max size is much bigger and we also
get a bad_alloc expection instead of a segfault (which we can catch
*if* this ever becomes a pratical problem). No test for the crash
as its not reproducable with the MALLOC_ settings in framework.

Closes: 759612
Make Packages & Sources generation optional, during Generate call

refactor a bit, extract code out of Generate() into
DoGenerate{PackagesAndSources,Contents}, add new
APT::FTPArchive::ContentsOnly option to allow skipping the generation
of Package/Source files (if they are generated e.g. by some db outside
of apt-ftparchives control)
