commit 76e97d39 introduced a regression by having setDeviceConnectionState()
force a device change on duplicated outputs even if the selected device is 0.
This also forces a device 0 for the two outputs it is duplicated to,
which may override a valid device selection on those outputs and apply
default volumes.

Fix a small parsing error in parsing the supported formats and sample
rates of a stream out with dynamic values for these parameters. The
channel mask parser was properly skipping the "=" in the setting
string, but formats and sample rates were not (cauing the first
reported format and sample rate to end up being skipped)

Fix is a bug in checkOutputsForDevice() which makes that we can
try to reopen an output stream after a new device is connected because
we believe that no opened output is available for this device.

Changes for new audio devices enums:
- legacy audio HAL wrapper provides conversion between new and

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.

Audio hw modules are now loaded according to configuration

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.

and getNewDevice() methods.

Map the NOTIFICATION stream type to a new strategy,

when a headset is in use for media playback.
