shill: power management framework

Add handling of the PowerStateChange event from the power manager.

BUG=chromium-os:22407
TEST=Manual.  Created an instance of PowerManager and verified that signals are
received when the lid is closed and opened.  Verified that when using the root
path, RegisterSuspendDelay is received by powerd.
