upstart user session leaks all the dbus events it receives

Fix Released
Bug description:
[Impact]
The unity-panel-service process has been caching D-Bus messages sent
from upstart, effectively leaking memory. The solution replaces the
offending code with a single upstart event emission.
[Test Case]
0. Make sure there is a user session job with a dbus rule (eg unity-greeter-session-broadcast)
1. Install and run system-load-indicator (indicator-multiload)
2. Set the update interval to 100ms
3. Now watch the memory use of init --user increase by 100kb per second
4. Also open up upstart-monitor to see all the dbus messages being sent
[Regression Potential]
Some kind of hidden functionality depending on upstart events sent
through D-Bus to the unity-panel-service may have become disconnected.
Unlikely.
[Other Info]
The fix for Ubuntu 14.04 LTS was cherry picked from the Ubuntu "Vivid
Vervet" dev release where it has been in regular use for some time
without apparent regression.
