Created after hardware/audio_effect.h with the following changes: - names changed to satisfy HAL style guide; - defined an interface per effect, an interface method per command, and getter / setter methods for properties; - retained methods for executing proprietary commands and accessing proprietary properties, only to be used for third-party software effects; - HIDL vector type is used instead of count / array pairs; - provider callback changed to be used over RPC; - 'dump' is method is already defined by generated code. Note that audio data is currently transferred using AudioBuffers, which is not effective due to memory copy and HwBinder transaction involved. The transfer method will be changed to FastMessageQueue.
