setting fake properties.
healthd used to check for registered charger drivers to determine if the
device is an always-plugged device with no battery. This patch changes
it to check for battery instead.

With Type-C PD, VBUS can no longer be assumed to
to be at 5V. Read the "voltage_max" field from the
power_supply class node and export it through
BatteryProperties service.

Use 1972 as a right delineation. Otherwise use half way point
between the monotonic and realtime. Treat correction factor as
unsigned, ensure that any wrapping to a negative value is
dropped or set to EPOCH. Acknowledge that we can get a more
accurate time track by acquiring the time rather than relying on
healthd timestamp.

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.

* Replace unnecessary warnings about missing attributes with a more
informative message when no battery devices provided by the system.
* Turn off periodic battery checks when no battery devices (thereby
reducing unnecessary kernel log spam).
* Replace battery properties in log messages with a more informative
message when no battery is provided or the battery is removed.

* add ops for different "modes" of healthd operation: android vs. recovery
* recovery mode selected by runstring options -r
* binder/Android communication moved to android mode
* recovery mode ops avoiding binder service registration
* "no service manager" flag removed; now handled by android vs. other modes
