* merge the remaining Ubuntu change:

  - on gpg verification failure warn and restore the last known
    good state
  - on failure display the IP of the server (useful for servers
    that use round robin DNS)
  - support Original-Maintainer in RewritePackageOrder
  - enable cdrom autodetection via libudev by default
  - show messsage about Vcs in use when apt-get source is run for
    packages maintained in a Vcs
  - better support transitional packages with mark auto-installed. 
    when the transitional package is in "oldlibs" the new package
    is not marked auto installed (same is true for section
    metapackages)
  - provide new "deb mirror://archive.foo/mirrors.list sid main"
    method expects a list of mirrors (generated on the server e.g.
    via geoip) and will use that, including cycle on failure
  - write apport crash file on package failure (disabled by default
    on debian until apport is available)
  - support mirror failure reporting (disabled by default on debian)
