- Provide HAL for vendors to turn on VR-specific device performance
settings when we enter VR mode in VrManagerService.

- vehicle hal is used for supporting car specific features.
- Each property can be written (=set), read (=get), or subscribed.
- Each property has configuration informaiton to tell what that property
is and how it can be accessed.
- also adding dummy hal implementation.

This HAL was intended to support doze mode but it is currently
unused and it's best for it to stay that way.

HAL for physical TV input such as HDMI-in. The main purpose is to
provide sideband video stream source handle to feed SurfaceFlinger and
audio related information to feed AudioManager (TBD).

Android's implementation of vibrator needs to be done inside a
hardware module, so that it can make a vendor implementation possible.
Hw module's name becomes vibrator.default.so.
This change is related to other changes in:
- frameworks/base
- hardware/libhardware_legacy
- device/generic/goldfish
- platform/build

Squashed commit of:
Move sensors multi HAL to libhardware
Added a SensorEventQueue, a circular buffer meant for reading with one thread
and polling a subhal with another. The writing thread gets access to pointers
in the internal buffer. This design avoids a memcpy on write when the multihal
fetches subhal events using poll().
Unit-tests include multithreaded reading and writing lots of events, in
random-sized chunks.
This is not used by the multihal yet. That will be a different CL.
MultiHal multithreaded polling
Tests SensorEventQueue I/O when the queue is full.
Reduced debug logging in multihal.
deactivated multihal logspam, made warnings warnings, left critical startup info
Removed unneeded linux/input.h includes, to fix Mac SDK build

This is meant to be an example and a reference for device manufacturers
on how to build a new Camera v2 HAL. This first patch has basic
configuration and entry/exit.

Change the signature of set_local_slew.
Changed the definition of the slew function in the local time HAL to take an
int16 instead of an int32 and to use the full range of the int instead of
attempting to imply any particular PPM range.

Remove "primary" from the local_time HAL.
Interface instances are a pattern which should only be used by audio. Remove
its use from the local_time HAL.

Refactor the local/common clock services.
This change is one of a set of 5 changes made to different repositories. Look
for this comment in all of them.
Refactor the local/common clock services to match android best
practice. Notable changes include
+ The kernel no longer knows anything about common time. Common time has been
moved completely up into user land. This has an impact on the accuracy of the
timesync debugging code, and the netfilter assisted approach to network based
timesync is going to have to be modified.
+ The timesync driver used by A@H is now just local time driver.
+ The kernel no longer needs access to the linear transform math code, and it
has been removed.
+ A new HAL has been introduced to expose the concept of local time to the
system.
+ A non-slewable stub implementation of the local time HAL based on
CLOCK_MONOTONIC has been added.
+ The old library has been eliminated. Its functionality has been
distributed among the common time binder service, the local time hal and the
linear transform utility code.
+ All clients of the old library have been changed to be clients of
the binder service, the hal and the utility code.
+ The reset_tt utilities have been removed, they no longer have a purpose in the
system.

First implementation of a NFC HAL. This implementation doesn't
offer a generic NFC device HAL (yet), but offers typed interfaces
for different NFC controllers. Currently only the PN544 is supported.
