Modified getOutput() logic to not systematically
open a new direct output when a profile matches a request.
This causes a problem when transitioning between two
multichannel tracks as the audio HAL will most of the times
only support one direct output stream open at a time.
Instead, reuse an open output if all the parameters match
or force close the output before reopening it.
Also modify releaseOuput():
- close a direct output only if no client is using it anymore
- call closeOutput() instead of removing the output from
the open output list: this factors in code executed when closing an
output stream.

When answering a call in silent mode, music playing over A2DP
was not immediately muted by current audio policy manager logic.
The fix consists in muting media strategy on all output streams
immediately when entering in call.
Also add methods to AudioOutputDescriptor to report
recent global, per strategy and per stream activity.

There is a brief music interruption when a touch sound
is played the first time after the headset insertion.
This is due to a bug in audio policy manager logic to prevent
volume bursts while changing device while music is playing.
The fix consists in muting music only on current output stream
when changing device, not all output streams.
Also prevent unecessary device change if the requested device
is not supported by the output stream profile.

There is a delay inserted by audio policy manager before switching
device when entering in call mode to allow music playback to be muted
before the device actually switches.
This delay can be significant when high latency outputs (e.g. deep buffers) are
present and should not be applied if the output is not active.

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.

enum values from AudioSystemLegacy.h, of type audio_devices,
and some from /system/audio.h, of type audio_devices_t.

inspect what audio device type they correspond to.

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.
