Devices which have no battery and are always plugged in will not have
any battery property initialized. This causes the 'stable power' to
never be switched which is required for updating apps.
This change recognizes such a device and manually sets the battery to
100% and charger status to connected to AC mains. It will also fake the
battery temperature.

(cherry pick from commit acb1ddf56c)
Aid monotonic to realtime logging synchronization correction in
the Android ecosystem by providing a periodic notification. We
now have the following messages in the kernel logs:
- PM: suspend entry %Y-%m-%d %H:%M:%S.%09q UTC
- PM: suspend exit %Y-%m-%d %H:%M:%S.%09q UTC
- Suspended for %s.%03q seconds
- healthd: battery l=100 ... %Y-%m-%d %H:%M:%S.%09q UTC
Alter klogd to resynchronize on healthd messages as well.
NB: Time using strftime format, %q is a reference to fractional
second as introduced into log_time strptime method.

In charger-mode, power off/on screen as required, for efficient
charging.
Turn on screen on power-key press rather than on key-release.
On charge-cable removal, kick animation to show the correct battery
level.

Existing code allows charger-mode to exit to Android even with 0%
battery.
This might lead to more battery discharge while booting to Android,
especially if only USB-charger is connected, and thus certain
features/components not functioning as expected in Android.
This patch adds a configurable parameter to improve the user experience
by preventing the charger exit till battery capacity is good enough to
boot Android

Adds a callback to the healthdHAL which can check for device specific
properties to decide if the screen should turn on.

If charger is connected and battery capacity is 0, charging animation should
run. The device would be booted up even if capacity is 0 in off-mode charging.
At that time, it would take some time to be 1 from 0 for capacity if you
use USB charger.

Logic for this check was inadvertently reversed when porting this from
the charger daemon to healthd. Request suspend if a charegr is connected,
else stay out of suspend waiting for a charger connect or power off if
none.

reports 42% battery charge and 42.2 degrees temperature.

At present, charging animation runs irrespective of whether charger is
connected or not. When the charger is disconnected, device does not
shutdown for 10sec. Charger animation during this period should be
avoided.

The minui library has changed to no longer use libpixelflinger. It
also offers a more efficient way of storing and loading frames of
animation; use it to represent the battery-full state images.
Also removes the unused battery_charge.png image.
