Add UUID (re-)scan support for vold-mounted volume (1/2)

Consider the following scenario:
* Using physical primary only storage cofigurations with the sdcard
  daemon
* On first boot, the UUID is plumbed to the framework via vold, but this
  is only done when a volume is mounted (via the extractMetadata()
  function).
* When the framework crashes/restarts, vold does not need to mount any
  volumes (as the sdcard daemon will still be running), which means
  that the UUID is never plumbed to the framework upon restart.
* MediaProvider will continuously crash with an NPE due to the UUID being
  null.

Workaround the issue by adding "scanuuid" to the "vdc volume" command
list, and trigger a scan when the framework detects that a volume is
mounted but the UUID is null.

Fix circle battery opaqueness for the low battery color

Because of the DST_ATOP Xfermode the color was drawn below the full
gray ring resulting in a washed out red. Fix this by not setting an
Xfermode and drawing the color normally.
This does not affect the non-low color as it cannot get any whiter.

Animate circle battery rotation back to 0 after unplugging

Alarm: ignore less than 2 mins upcomming power off alarm

2 minutes is our define for enough boot up time for a power off alarm.
For current design, it can only afford upcoming power off alarm which
is later than 2 minutes. Kernel alarm driver only take care the power
off alarm which is 2 minutes later. And the framework only pass the
first power off alarm to kernel. So we need to find the first 2
minutes later upcomming power off alarm to kernel, otherwise it will
be no power off alarm from kernel's perspective. Fix the bug by
ignoring less than 2 mins upcomming alarm as power off alarm, and
only treat it as a normal alarm.
