Separated current and V3 VHAL impls

This allows us to define V3-specific modules so that we can create
reference VHAL implementations that do not depend on implementing V4
(current) AIDL APIs

+# AIDL VHAL libraries and reference implementation.
+---
+
+This directory stores the libraries useful for implementing vendor AIDL VHAL.
+This directory also stores a reference fake implementation for AIDL VHAL.
+
+## default_config
+
+Stores the default vehicle property configurations for reference vehicle HAL.
+Vendor implementation could copy this library but must update the configuration
+to meet their own requirements, e.g. enable or disable certain properties or
+update the initial value for certain properties.
+
+##	fake_impl
+
+Contains libraries used specifically for the fake reference VHAL implementation.
+These libraries are for test only and must not be directly used for vendor
+VHAL implementation.
+
+These libraries contain test-spcific logic and must not run directly on a real
+vehicle.
+
+## grpc
+
+Stores code for GRPC based VHAL implementation.
+
+## hardware
+
+Defines an interface `IVehicleHardware.h` which vendor must implement for
+vehicle-specific logic if they want to follow our reference VHAL design.
+
+## proto
+
+Stores Some protobuf files translated from AIDL VHAL interface types. These
+files are used in GRPC VHAL implementation.
+
+## utils
+
+Defines a library `VehicleHalUtils-V3` which provides useful utility functions for
+VHAL implementation. Vendor VHAL could use this library.
+
+## vhal
+
+Defines a library `DefaultVehicleHal` which provides generic logic for all VHAL
+implementations (including reference VHAL). Vendor VHAL implementation could
+use this library, along with their own implementation for `IVehicleHardware`
+interface.
+
+Also defines a binary `android.hardware.automotive.vehicle@V3-default-service`
+which is the reference VHAL implementation. It implements `IVehicle.aidl`
+interface. It uses `DefaultVehicleHal`, along with `FakeVehicleHardware`
+(in fake_impl). It simulates the vehicle bus interaction by using an
+in-memory map. Meaning that all properties (except for some special ones) are
+just written into a hash map and read from a hash map without relying on any
+hardware. As a result, the reference implementation can run on emulator or
+any host environment.
+
+Vendor must not directly use the reference implementation for a real vehicle.

+# Fake reference AIDL VHAL implementation libraries
+---
+
+This directory stores libraries for implementing a fake reference AIDL VHAL.
+
+WARNING: All the libraries here are for TEST ONLY.
+
+## GeneratorHub
+
+Defines a library `FakeVehicleHalValueGenerators-V3` that could generate fake
+vehicle property values for testing.
+
+## hardware
+
+Defines a fake implementation for device-specifc interface `IVehicleHardware`:
+`FakeVehicleHardware`. This implementation uses a in-memory map for storing
+property values and does not communicate with or depending on any specific
+vehicle bus.
+
+## obd2frame
+
+Defines a library `FakeObd2Frame` that generates fake OBD2 frame for OBD2
+properties.
+
+## userhal
+
+Defines a library `FakeUserHal` that emulates a real User HAL behavior by
+parsing debug commands.
