This change moves all Wifi HAL headers to libhardware_legacy; and moves
hal implementation under hardware/<vendor>/wlan. This way different
vendors will be able to tailor implementation to their drivers.

The existing openOutputStream API did not allow passing stream flags even
though its audio hardware interface's open_output_stream counterpart does take
a "flags" argument. This means that, when the audio hw_module is implemented
using libhardware_legacy, the output flag was lost.
This commit adds an API in libhardware_legacy's audio module, allowing to pass
the flag, and updates the default wrapper in order to call this new API instead
of the old version that missed the flag.

Do not allow offloading if one non offloadable effect is enabled. This prevents from
creating an offloaded track and tearing it down immediately after start when audioflinger
detects there is an active non offloadable effect.
Not doing so breaks gapless playback because AwesomePlayer will always be able to open
an offloaded track which will not be compatible with the previous PCM track and
Audiosink::open() will not recycle it.

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 switching audio path, it is sometimes required

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.

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.

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.

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 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
