http://bugs.debian.org/457400
http://bugs.debian.org/459682
* Added patch from Aaron M. Ucko <ucko@debian.org> to allow trousers to
  build successfully on amd64, and presumably also other 64-bit
  architectures (Closes: #457400).
* Including udev rule for /dev/tpm from William Lima
  <wlima.amadeus@gmail.com> as suggested by David Smith <dds@google.com>
  (Closes: #459682).
* Added lintian overrides.
