Added specific volume curves for AUDIO_STREAM_SYSTEM,
AUDIO_STREAM_ENFORCED_AUDIBLE and AUDIO_STREAM_DTMF.
Volume for these streams tracks AUDIO_STREAM_RING on phones
and AUDIO_STREAM_MUSIC on tablets but is contrained in the range
-24dB to -6dB on speaker and -24dB to -12dB on headset.
STRATEGY_ENFORCED_AUDIBLE routing policy is now the same as
STRATEGY_MEDIA in countries where not enforced.

The addition of the per device volume feature has introduced
a problem where a volume burst can be heard in the headphones
just after insertion if the speaker volume is much higher than the
headphones volume.
Added a temporary mute of the output when switching device to force
volume ramp to 0 and back up to new volume.

Added definitions for parsing deep buffer flags in output profiles.
Make sure that sound start is delayed enough to allow
duck/mute effect to apply before starting a notification on an output

Audio hw modules are now loaded according to configuration
data read from audio_policy.conf. They are not loaded anymore
from a hardcoded list in AudiFlinger.
Output and input streams are opened on the hw module by which
they are exposed.
Also removed obsolete "acoustics" flags for input streams.

The audio policy manager implementation now reads a configuration file at
boot time that contains descriptors for available audio hardware
modules and for each module the profiles of available inputs and outputs streams.
The configuration file path on the target is: /system/etc/audio_policy.conf.
A default configuration file is given that defines a basic configuration
with one primary audio hw module capable of playback and capture.
Each platform or device should have its own audio_policy.conf file.
Also removed default value of fromCache argument of getDeviceForStrategy()
and getNewDevice() methods.

Map the NOTIFICATION stream type to a new strategy,
named STRATEGY_NOTIFICATION_RESPECTFUL, which differs
from STRATEGY_NOTIFICATION in that, when media is
playing, the notifications will use the same output
as the MEDIA strategy. This will results in the
notifications not being duplicated on the speaker
when a headset is in use for media playback.

This change makes support for A2DP related audio policy more generic:
-removed WITH_A2DP compilation switch
-use output profile descriptors listing the parameters
(sampling rate, format...) devices and attributes (low power, tunneling...)
for each available output.
All the behavior specific to A2DP is derived from the A2DP output profile
descriptor.
- removed obsolete a2dpUsedForSonification() method.
This is a first step towards a more generic support for different audio
hardware modules (USB, HDMI) and output streams supporting different
combinations of parameters (sampling rate, format...) and attributes
(low power, tunneling...).
Ultimately, the hw modules and output descriptors will loaded from a
configuration file.

Improve volume management by keeping track of volume for each type
of device independently.
AudioPolicyManagerBase now keeps track of stream volumes for each device
and apply volume according to current device selection.
Methods to set and get stream volume now specify the device class.
A value for "default" device is always present for each stream and is used
if a device is selected and no specific volume was ever set for this device.

Add a default implementation of get_next_write_timestamp to the C <--> C++
legacy audio HAL implementation allowing HALs using the legacy C++
AudioStreamOut to overload and implement get_next_write_timestamp. Default
implementation returns INVALID_OPERATION to indicate that the functionality is
not supported.

When no DRC is applied by the platform when playing
over the device speaker, faint audio signals are not boosted and
barely audible until the media volume is raised to about one fourth
of the range.
Compensate this by applying a different volume curve for music stream
when the speaker is selected.

Modified the volume curve for ringtones and notifications
in audio policy manager. The first volume step now corresponds to
-30dB instead of -50dB thus making ringtone much more
audible for low volume settings.
Also made a generic implementation of volume curves according to
audio policy strategies.

This doesn't actually create a HAL, but rather a set of helper static
libraries that device specific libraries (i.e. the old libaudio pieces)
can link against to create a proper audio HAL module.
We provide an audio_policy static wrapper and audio hardware interface
static wrapper.

There is a bug in the way audio policy manager handles A2DP interface suspend/restore
when SCO is used. This bug is not new but has been triggered by a change in the timing
of the events received by audio policy manager when a call is setup and torn down
introduced by commit 164a8f86c7e48992691368c4895709c3bdb835a4.
The fix consists in grouping the control of A2DP suspended state in a single function
that is called systematically when conditions affecting this state are changed:
- call state change
- device connection/disconnection
- change in forced usage.

The fix for issue 2952766 showed some unused code in
AudioPolicyManagerBase::checkOutputForStrategy(): since commit
eb8f850d0b7e53956e917fd9645f808c1a09bc88: there is no need
to update the hardware output device as it will be updated when the
new tracks are created by audioflinger.

Added methods for audio effects management by audio policy manager.
- control of total CPU load and memory used by effect engines
- selection of output stream for global effects
- added audio session id in parameter list for startOutput() and stopOutput().
this is not used in default audio policy manager implementation.

The problem is that the code in AudioPolicyManagerBase::checkAndSetVolume() that forces
voice volume to max when setting bluetooth SCO volume is not called if the bluetooth stream
volume did not actually change. So even if we re apply volumes when switching to bluetooth
device, the voice volume is not changed in audio HAL and remains what it was when routed to earpiece.
What makes things worse on Passion is that stream volumes are limited when connected to bluetooth
and their actual value does not change as soon as they exceed the limit threshold.

The noise is the residual ring tone that is still playing while the call is answered and the
audio route changed to headset or earpiece.
The fix consists in muting the ringing tone when changing mode from ringtone to in call
and delaying the route change until the audio buffers are emptied.
First implementations of audio policy manager in Eclair branch have shown that most code is common to all platforms.
Creating AudioPolicyManagerBase base class will improve code maintainability and readability.
