Title:
  fd reception code is not exeception-safe when unexpected numbers of
  fds are received

Status in Mir:
  Fix Released
Status in mir package in Ubuntu:
  Fix Released

Bug description:
  the easiest way to see this is to inspect mir::receive_data, or to run
  valgrind with track-fds = yes

  In the wild, this would only leak 1-4 fd's per error. Given the type
  of errors that would cause this, it would take a lot of rare errors
  before we hit the process fd limit.
