Title:
  Stale trusted socket may stop Unity8 from restarting after an abnormal
  exit

Status in “unity8” package in Ubuntu:
  New

Bug description:
  In some cases (like bug #1371593) unity8 crashes leaving the
  mir_socket and mir_socket_trusted sockets in the filesystem. When
  unity8 tries to restart it fails with "bind: address already in use"
  because of the left over mir_socket_trusted.

  There are two aspects to this bug:

  1. The unity8 upstart script should clean up the trusted socket before starting, like it does for the normal socket
  2. If Mir is instantiated using the mir::run_mir() helper function, it is able to clean up the sockets even when the server crashes. However unity8 doesn't currently use the helper (also see bug #1371621).
