Refactor AudioPolicyManager
AudioPolicyManager implementation is now split into the
following files:
files managerdefault/Gains.*
class AudioGain
class VolumeCurvePoint
class StreamDescriptor
files managerdefault/Devices.*
class DeviceDescriptor
class DeviceVector
files managerdefault/Ports.*
class AudioPort
class AudioPortConfig
class AudioPatch
files managerdefault/IOProfile.*
class IOProfile
files managerdefault/HwModule.*
class HwModule
files managerdefault/AudioInputDescriptor.*
class AudioInputDescriptor
files managerdefault/AudioOutputDescriptor.*
class AudioOutputDescriptor
All files for libaudiopolicyservice are moved under service/
All files for libaudiopolicymanager are moved under manager/
