utterance capture.
Sound trigger service

Use the class factory to create the audio policy mamager
instead of AudioPolicyManager class constructor and
use a pointer to an AudioPolicyInterface.

Do not define USE_LEGACY_AUDIO_POLICY by default.
By default, all devices will now use the new audio policy implementation
in AudioPolicyManager.cpp
To continue using the legacy audio policy implemented by
AudioPolicyManagerBase in libhardware_legacy a device should
define USE_LEGACY_AUDIO_POLICY in its makefile.

Split audio policy library into a service part and a policy part.
This will allow OEMs to customize the policy part:
- libaudiopolicyservice for the service.
- libaudiopolicymanager for the policy.
Two build options can be defined in device make file to select
the policy library:
- USE_LEGACY_AUDIO_POLICY = 1: this will use the legacy policy
in hardware/libhardware_legacy implemented by AudioPolicyManagerBase class.
This policy is loaded as a harware module and exposes the audio policy HAL
defined in include/hardware/audio_policy.h and is in a library called
audio_policy.XXX.so (e.g audio_policy.default.so)
The legacy HAL will not be updated with new features.
If USE_LEGACY_AUDIO_POLICY is not defined, the policy is implemented by
a class named AudioPolicyManager exposing an interface defined in
AudioPolicyInterface.h.
The corresponding library is libaudiopolicymanager.so.
New features will be added only to AudioPolicyInterface.h
The default implementation is provided here in file AudioPolicyManager.cpp
OEMs wanting to cutomize the policy can implement the AudioPolicyManager class
and provide the libaudiopolicymanager.so library.
In this case the device make file should define:
- USE_CUSTOM_AUDIO_POLICY = 1
For now, USE_LEGACY_AUDIO_POLICY = 1 is forced in audio policy service make file.
This will be removed when the new audio policy is enabled.

Add build option USE_LEGACY_AUDIO_POLICY to use either new
audio policy manager in local AudioPolicyManager.cpp
or the legacy AudioPolicyManagerBase.cpp via the policy HAL.
New features will be implemented only by the new audio policy manager.
Platform customiization will be by config file or new policy HAL.
AudioPolicyClientImplLegacy.cpp copied from AudioPolicyClientImpl.cpp
AudioPolicyInterfaceImplLegacy.cpp copied from AudioPolicyInterfaceImpl.cpp
New implementations of AudioPolicyInterface and AudioPolicyClient talking directly to
AudioPolicyManager.

Split audio policy service implementation to ease
further evolution:
AudioPolicyInterfaceImpl.cpp contains the implementation of
IAudioPolicyService interface
AudioPolicyClientImpl.cpp contains the implementation of the
AudioPolicyManager client interface
AudioPolicyService.cpp contains the rest of the code mostly
command threads implementation and pre processing management.
AudioPolicyService.cpp:
