* French manpage translation update

* spot & fix various typos in all manpages
* German manpage translation update
* cmdline/apt-cache.cc:
  - remove translatable marker from the "%4i %s\n" string
* buildlib/po4a_manpage.mak:
  - instruct debiandoc to build files with utf-8 encoding
* buildlib/tools.m4:
  - fix some warning from the buildtools
* apt-pkg/acquire-item.cc:
  - add configuration PDiffs::Limit-options to not download
    too many or too big patches (Closes: #554349)
* debian/control:
  - let all packages depend on ${misc:Depends}
* share/*-archive.gpg:
  - remove the horrible outdated files. We already depend on
    the keyring so we don't need to ship our own version
* cmdline/apt-key:
  - errors out if wget is not installed (Closes: #545754)
  - add --keyring option as we have now possibly many
* methods/gpgv.cc:
  - pass all keyrings (TrustedParts) to gpgv instead of
    using only one trusted.gpg keyring (Closes: #304846)
* methods/https.cc:
  - finally merge the rest of the patchset from Arnaud Ebalard
    with the CRL and Issuers options, thanks! (Closes: #485963)
