Add the following methods to IModule:
- getTelephony;
- get/setMasterMute;
- get/setMasterVolume;
- get/setMicMute;
- updateAudioMode;
- updateScreenRotation;
- updateScreenState;
The "update..." methods are "informational," the HAL may ignore
them and must not raise any errors.
ITelephony currently contains 2 methods:
- getSupportedAudioModes;
- switchAudioMode.
This "switchAudioMode" must validate the argument, and must
switch the HAL to the new mode synchronously.
Implement and add VTS tests.
