Merge lp:~xnox/upstart/fix-1235649 into lp:upstart

[Dimitri John Ledkov]

workaround #1
blacklist SPAM event in upstart-udev-bridge, thus not emitting system event nor re-emitting it to session-init.

this still leaves systemd-udev to consume 5% CPU constantly when the screen is on.

Will work on a systemd-udev patch.

[James Hunt (jamesodhunt)]

- Formatting is not standard: missing space after function name and before bracket. Aslo, why brackets round 'action' and 'kernel'?
- This is an ubuntu-specific work-around so should only be applied to Ubuntu if absolutely necessary.

Ignore VSYNC events from omapfb, as not needed and cause spam when re-emitted to session init.
