* merge of the debian-expermental-ma branch

  
* debian/control:
  - add dependency on zlib-dev for libapt-pkg-dev
* apt-pkg/cacheset.cc:
  - [ABI BREAK] add an ErrorType option to CacheSetHelper
* cmdline/apt-cache.cc:
  - use Notice instead of Error in the CacheSetHelper messages
    for compat reasons. Otherwise tools like sbuild blow up
  - return success in show if a virtual package was given
* debian/control:
  - remove libcurl3-gnutls-dev alternative as the package is gone
  - increase needed version of libcurl4-gnutls-dev to >= 7.19.0
    as we use CURLOPT_{ISSUERCERT,CRLFILE} (Closes: #589642)
* apt-pkg/deb/dpkgpm.cc:
  - Write architecture information to history file.
  - Add to history whether a change was automatic or not.
* apt-pkg/contrib/fileutl.cc:
  - Add FileFd::OpenDescriptor() (needed for python-apt's #383617).
* cmdline/apt-get.cc:
  - Support large filesystems by using statvfs64() instead of statvfs()
    and statfs64() instead of statfs() (Closes: #590513).
* apt-pkg/cdrom.cc:
  - Use link() instead of rename() for creating the CD database backup;
    otherwise there would be a short time without any database.
* apt-pkg/depcache.cc:
  - handle "circular" conflicts for "all" packages correctly
* cmdline/apt-cache.cc:
  - be able to omit dependency types in (r)depends (Closes: #319006)
  - show in (r)depends the canidate per default instead of newest
  - share the (r)depends code instead of codecopy
* apt-pkg/cacheset.cc:
  - move them back to the library as they look stable now
  - add a 'newest' pseudo target release as in pkg/newest
* apt-pkg/pkgcache.cc:
  - prefer non-virtual packages in FindPreferredPkg (Closes: #590041)
* test/integration/*:
  - add with bug#590041 testcase a small test "framework"
* apt-pkg/orderlist.cc:
  - try to install another or-group member in DepRemove before
    breaking the or group (Closes: #590438)
  - configure also the replacement before remove by adding Immediate flag

* apt-pkg/contrib/error.{cc,h}
  - docstring cleanup
  - add inline DumpError() to avoid subtle API break
* apt-pkg/contrib/error.{cc,h}:
  - remove constness of va_list parameter to fix build on amd64 and co
    Thanks Eric Valette! (Closes: #588610)
* apt-pkg/deb/debmetaindex.cc:
  - do not query each architecture for flat file archives
  - fix typo preventing display of architecture in Info()
* methods/bzip2.cc:
  - add a copycat of the old gzip.cc as we need it for bzip2 and lzma
* debian/rules:
  - Make DEB_BUILD_OPTIONS=noopt actually work by passing the right
    CXXFLAGS.
* apt-pkg/contrib/fileutl.{h,cc}:
  - Add support for reading of gzipped files with the new "ReadOnlyGzip"
    OpenMode. (Closes: #188407)
  - Link against zlib (in apt-pkg/makefile) and add zlib build dependency.
  - [ABI BREAK] This adds a new private member to FileFd, but its
    initialization is in the public header file.
* configure.in:
  - Check for zlib library and headers.
* apt-pkg/acquire-item.cc, apt-pkg/deb/debindexfile.cc,
  apt-pkg/deb/debrecords.cc, apt-pkg/deb/debsrcrecords.h,
  cmdline/apt-cache.cc:
  - Open Packages, Sources, and Translations indexes in "ReadOnlyGzip" mode.
* apt-pkg/deb/debindexfile.cc:
  - If we do not find uncompressed package/source/translation indexes, look
    for gzip compressed ones.
* apt-pkg/acquire-item.cc:
  - If the Acquire::GzipIndexes option is true and we download a gzipped
    index file, keep it as it is (and rename to .gz) instead of
    uncompressing it.
* doc/apt.conf.5.xml:
  - Document the new Acquire::GzipIndexes option.
* doc/po/apt-doc.pot, doc/po/de.po:
  - German translation of new Acquire::GzipIndexes option.
* Add test/test-indexes.sh:
  - Test behaviour of index retrieval and usage, in particular with
    uncompressed and gzip compressed indexes.
* methods/gzip.cc: With FileFd now being able to read gzipped files, there
  is no need for the gzip method any more to spawn an external gzip process.
  Rewrite it to use FileFd directly, which makes the code a lot simpler, and
  also using less memory and overhead.
* doc/apt.conf.5.xml:
  - add and document APT::Cache-{Start,Grow,Limit} options for mmap control
* apt-pkg/contrib/fileutl.cc:
  - do not fail von double close()
* cmdline/cacheset.cc:
  - doesn't include it in the library for now as it is too volatile
  - get the candidate either from an already built depcache
    or use the policy which is a bit faster than depcache generation
  - get packages by task^ with FromTask()
  - only print errors if all tries to get a package by string failed
  - factor out code to get a single package FromName()
  - check in Grouped* first without modifier interpretation
* cmdline/apt-get.cc:
  - use the cachsets in the install commands
  - make the specify order of packages irrelevant (Closes: #196021)
* apt-pkg/orderlist.cc:
  - untouched packages are never missing
* apt-pkg/packagemanager.cc:
  - packages that are not touched doesn't need to be unpacked

  - complete rewrite but use the same API
  - add NOTICE and DEBUG as new types of a message
  - add a simple stack handling to be able to delay error handling
* apt-pkg/aptconfiguration.cc:
  - show a deprecation notice for APT::Acquire::Translation
* apt-pkg/contrib/configuration.{cc,h}:
  - add a wrapper to match strings against configurable regex patterns
* apt-pkg/contrib/fileutl.cc:
  - show notice about ignored file instead of being always silent
  - add a Dir::Ignore-Files-Silently list option to control the notice
* apt-pkg/policy.h:
  - add another round of const& madness as the previous round accidentally
    NOT overrides the virtual GetCandidateVer() method (Closes: #587725)
* apt-pkg/pkgcachegen.{cc,h}:
  - make the used MMap moveable (and therefore dynamic resizeable) by
    applying (some) mad pointer magic (Closes: #195018)

  - make the apt/term.log output unbuffered (thanks to Matt Zimmerman)
* methods/ftp.h:
  - Handle different logins on the same server (Closes: #586904).
* apt-pkg/deb/deblistparser.cc:
  - Handle architecture wildcards (Closes: #547724).
* apt-pkg/versionmatch.cc:

  - Make FileFd replace files atomically in WriteTemp mode (for cache, etc).
* debian/control:
  - Set Standards-Version to 3.9.0
* apt-pkg/cachefile.h:
  - make pkgPolicy public again, libapt-pkg-perl (and probably
    others) get unhappy without that
* merge the remaining Ubuntu change:
  - on gpg verification failure warn and restore the last known
    good state

    that use round robin DNS)

    packages maintained in a Vcs

    method expects a list of mirrors (generated on the server e.g.

  - correct "Dangerous iterator usage" pointed out by cppcheck
  - deal with long long, not with int to remove 2GB Limit (LP: #250909)

  - remove duplicate architectures in getArchitectures()
* apt-pkg/indexrecords.{cc,h}:
