Keep quiet when volume keys are used to wake up device

- Userspace will make a 'beep' with it receives a key up, so
  consume that event as well.

SystemUI: status bar brightness: store value as int

Non-automatic brightness value is stored as int, not float.

Symptom: adjust the brightness in the status bar, the brightness
         slider in the notification bar will always be set to full

HeadsUp: fix settings not being applied after reboot

blacklist and dnd setting were not being applied at boot
clean up the SettingsObserver
MountService: Add support for multiple storage configurations

Currently AOSP only supports a single storage configuration that is hardcoded
in storage_list.xml. Some device updates are now merging data and internal
storage partitions, and as a result require the storage list to support two
different variations.

By utilizing the sys.storage_legacy property this will allow for the framework
to support multiple configurations which can be determined during boot.
