A lot of code (including clients of AudioFlinger) use constants
and structs from hardware/audio_effect.h for convenience, without
actually interacting with HAL. Thus these definitions are more
like the ones from system/audio.h and need to be moved to system/.
Test: make

Add a flag for effect descriptor indicating that the effect does not
implement a process function. This tells the framework that no
latency or performance penalty comes with enabling this effect.
When this flag is set, the process function does not have to be implemented
by the effect implementation.

Added EFFECT_CMD_OFFLOAD command to audio effect control
interface. It is used by the framework to indicate if
the playback thread the effect is attached to is offloaded
of not.
Added effect flag EFFECT_FLAG_OFFLOAD_SUPPORTED indicating if
the effect implementation supports offloading to a DSP.

A special value for NULL effect UUID is declared as const
in audio_effect.h. This prevents several modules including
audio_effect.h to be linked together.
The fix consists in declaring the value as static const.

Added API to query and configure effects supporting auxiliary channels.
An auxiliary channel contains an additional audio signal helping in the
processing of the main channel. An example is a dual mic noise suppressor
were the main channel contains the signal from the main mic and the aux channel
containss the signal from the sub mic.

Renamed audio effect library interface command for audio format
configuration from EFFECT_CMD_CONFIGURE to EFFECT_CMD_SET_CONFIG.
This makes the naming more consistent with other exixsting commands
and allow adding new a command to get the configuration (EFFECT_CMD_GET_CONFIG).
Same change for reverse channel configuration renamed from
EFFECT_CMD_CONFIGURE_REVERSE to EFFECT_CMD_SET_CONFIG_REVERSE.

Moved and renamed media/EffectApi.h to hardware/audio_effect.h
Modified the effect library API to expose a library info structure
containing an interface functions table.
Also removed enums for audio channels, audio format and devices
from effect API and use values from system/audio.h instead.
