Implement user-settable power save whitelist.

The whitelist is now maintained by DeviceIdleController,
which is moving out into its own independent system service.
Network stats now queries it for the whitelist, instead of
collecting that itself.

Also did a few improvements in alarm manager -- made the
code for moving alarms out of the pending list more robust,
and fixed the debug output to always print the contents of
the pending list even if we aren't in a pending state.  (That
would have helped me identify the problem much earlier.)
