Changes for new audio devices enums:
- legacy audio HAL wrapper provides conversion between new and
old device enums. It exposes a rev 2.0 audio device API to the
audio framework and allow legacy implementation to use old device enums.
- AudioPolicyManager: use standard enum value for no device (0).

The AudioPolicyManagerBase implementation was using some device
enum values from AudioSystemLegacy.h, of type audio_devices,
and some from /system/audio.h, of type audio_devices_t.
Now only uses audio_devices_t, and associated functions to
inspect what audio device type they correspond to.
Added #define to represent "no audio device" to clarify code.
Removed unused variable in AudioPolicyManagerBase::startOutput()

When an HDMI sink is connected it is possible that
a direct output is made available for multichannel audio.
In this case, the list of outputs available to reach the HDMI device
after the connection is different from before. checkOutputForStrategy()
must take this into account in order to invalidate tracks so that
they can be re connected to the multi channel output if necessary.

setForceUse() should not force new device selection on outputs
if the selected device is 0. If a device 0 (no device) selection
is forced on a duplicated output, this causes volumes to be reset to
their default on outputs the duplicated output is connected to.
Also force reapply volumes when a new output is created. It is safer and more
explicit than relying on the fact that the selected volume is different
from default volume and thus is actually sent to audioflinger.

When switching audio path, it is sometimes required
to temporarily mute certain streams to avoid glitches.
The unmute command is sent with a delay but the volume applied
when unmuting is computed according to the state at the time of mute.
If the device selection changes after the delayed unmute is programmed
the new volume will not correspond to the new device.
setStreamMute() now accepts a device selection as input parameter which is
used instead of current device for volume computation.

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

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.

The change for volume per device introduced a problem where if a headset
is plugged in while in silent mode, the sound will not be restored
at the first press on volume up key but only at the second press.
This is because when exiting silent mode, AudioService reapplies the
last known volume for all devices in any order and the last volume
applied prevails, even if it is for a device other than currently selected
by audio policy manager.
The fix consists in applying a new volume only if the device indicated
matches currently selected device on an output.

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.

Increase the delay after muting music when switching audio path
to both speaker and headset for notifications and ringtones.
This is required to avoid a residual of music to be output to speaker
now that the max latency has been increased in low power playback mode.
This is a temporary workaround that will be removed when low power mode
is controlled policy manager.

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.
Change-Id: I03f316fb28150eda50b05dfa12310701e2674648
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.
