Add VTS tests for audio effects
Added tests covering IEffect, IEqualizerEffect, and
ILoudnessEnhancer interfaces.
Minor corrections in the interface definitions and implementations:
- fixed descriptions and @callflow annotations in IEffect;
- fixed type used for band levels in IEqualizerEffect;
- fixed specification of frequencies in IEqualizerEffect;
- fixed some bugs in previously non-execrices Effects code;
- warning messages changed to error messages.
Test: this is a test
