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.

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.

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.

Add an implementation of the new get_master_volume method to bridge from the new
C only audio HAL to the old C++ legacy audio HAL.

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.
