Audio routing part 2
- Added WIRED_HEADSET and SPEAKER to AudioModes
- Added WiredHeadsetManager class
- AudioRouter now listens to WiredHeadsetManager and PhoneUtils for
speakerphone
- AudioRouter maintains state across earpiece,headset,bluetooth,speaker
- Most code copied from InCallScreen for speaker logic
- CallHandlerService listens to audioRouter for audio states
- Moved Wired headset logic from phoneglobals to wiredheadsetmanager
- Better toString for logging Call objects
