[Merge] lp:~stgraber/upstart/upstart-make-event-bridge-usable into lp:upstart

[James Hunt]

Review: Needs Fixing

* extra/upstart-event-bridge.c: main():
  - Looks like user_session_path should be nih_local, whilst path_element should just be 'char *'?
  - If $HOME is not set, we fail to start. That's probably reasonable though as we display a couple
    of errors in that scenario.
