62f3617f2f4016ad2f59635d5156d64872989880 14-Aug-2011 Eric Laurent <elaurent@google.com> Deprecate use of some audio effects on output mix.

The possibility for applications to apply insert audio effects
(Equalizer, BassBoost, Virtualizer) on global output mix has brought up
a number of issue.

This change updates the java doc for audio effects indicating that
application should not apply insert effects globaly anymore as this behavior
will soon be deprecated.

The audio framework will still allow global insert effects during an interim
period but will give the priority to effects inserted on particular player by
disabling global effects when both are present.

0f7f4ece1b6b73caf608d533d833a8cdc11c8131 24-Jul-2011 Eric Laurent <elaurent@google.com> Added APIs for audio preprocessing

Added APIs to control pre processes applied on captured audio.
Those APIs are still hidden until reviewed by API council.

Three types of standard pre processes are supported:
- Automatic Gain Control (AGC) by AutomaticGainControl class
- Acoustic Echo Cancellation (AEC) by AcousticEchoCanceler class
- Noise Suppression (NS) by NoiseSuppressor class

A method is added to AudioEffect class to query audio pre processings
applied by default by the platform on a given AudioRecord session ID.

602b3286ffe7da6e70bf2d9e4861a5d74ff7c473 18-Mar-2011 Eric Laurent <elaurent@google.com> Fix issue 3509396: AudioEffect.getParameter JAVA.

Removed dead/buggy code in AudioEffect.getParameter() and
AudioEffect.command() that was meant to return the actual length of
meaningful data in the returned parameter or command reply.

This is replaced by the method return status indicating this length when
positive (negative return codes still indicate the same errors as before).

Modified automated AudioEffect tests accordingly.
