merge 'after squeeze release'-stuff

[ David Kalnischkies ]
* apt-pkg/depcache.cc:
  - add SetCandidateRelease() to set a candidate version and
    the candidates of dependencies if needed to a specified
    release (Closes: #572709)
* cmdline/apt-get.cc:
  - if --print-uris is used don't setup downloader as we don't need
    progress, lock nor the directories it would create otherwise
  - show dependencies of essential packages which are going to remove
    only if they cause the remove of this essential (Closes: #601961)
  - keep not installed garbage packages uninstalled instead of showing
    in the autoremove section and installing those (Closes: #604222)
  - change pkg/release behavior to use the new SetCandidateRelease
    so installing packages from experimental or backports is easier
  - really do not show packages in the extra section if they were
    requested on the commandline, e.g. with a modifier (Closes: #184730)
* debian/control:
  - add Vcs-Browser now that loggerhead works again (Closes: #511168)
  - depend on debhelper 7 to raise compat level
  - depend on dpkg-dev (>= 1.15.8) to have c++ symbol mangling
* apt-pkg/contrib/fileutl.cc:
  - add a RealFileExists method and check that your configuration files
    are real files to avoid endless loops if not (Closes: #604401)
  - ignore non-regular files in GetListOfFilesInDir (Closes: #594694)
* apt-pkg/contrib/weakptr.h:
  - include stddefs.h to fix compile error (undefined NULL) with gcc-4.6
* methods/https.cc:
  - fix CURLOPT_SSL_VERIFYHOST by really passing 2 to it if enabled
* deb/dpkgpm.cc:
  - fix popen/fclose mismatch reported by cppcheck. Thanks to Petter
    Reinholdtsen for report and patch! (Closes: #607803)
* doc/apt.conf.5.xml:
  - fix multipl{y,e} spelling error reported by Jakub Wilk (Closes: #607636)
* apt-inst/contrib/extracttar.cc:
  - let apt-utils work with encoded tar headers if uid/gid are large.
    Thanks to Nobuhiro Hayashi for the patch! (Closes: #330162)
* apt-pkg/cacheiterator.h:
  - do not segfault if cache is not build (Closes: #254770)
* doc/apt-get.8.xml:
  - remove duplicated mentioning of --install-recommends
* doc/sources.list.5.xml:
  - remove obsolete references to non-us (Closes: #594495)
* debian/rules:
  - use -- instead of deprecated -u for dh_gencontrol
  - remove shlibs.local creation and usage
  - show differences in the symbol files, but never fail
* pre-build.sh:
  - remove as it is not needed for a working 'bzr bd'
* debian/{apt,apt-utils}.symbols:
  - ship experimental unmangled c++ symbol files
* methods/rred.cc:
  - operate optional on gzip compressed pdiffs
* apt-pkg/acquire-item.cc:
  - don't uncompress downloaded pdiff files before feeding it to rred
  - try downloading clearsigned InRelease before trying Release.gpg
  - change the internal handling of Extensions in pkgAcqIndex
  - add a special uncompressed compression type to prefer those files
  - download and use i18n/Index to choose which Translations to download
* cmdline/apt-key:
  - don't set trustdb-name as non-root so 'list' and 'finger'
    can be used without being root (Closes: #393005, #592107)
* apt-pkg/deb/deblistparser.cc:
  - rewrite LoadReleaseInfo to cope with clearsigned Releasefiles
* ftparchive/writer.cc:
  - add config option to search for more patterns in release command
  - include Index files by default in the Release file
* methods/{gzip,bzip}.cc:
  - print a good error message if FileSize() is zero
* apt-pkg/aptconfiguration.cc:
  - remove the inbuilt Translation files whitelist
