This applies to the following types:
- audio_gain_mode_t;
- audio_flags_mask_t;
- audio_channel_representation_t;
- audio_channel_mask_t;
- audio_devices_t.
Enum types are distinct thus proper overloading on the type
is possible in C++. Also, assignments to enum types are
less prone to errors.

Fix some (note the fun infinite recursion bug from the dawn of time,
apparently no one has called that function), silence those that are
style choices.

Pass device address (and audio source for inputs) to
open_output_stream() and open_input_stream() audio HAL functions.
Bug: 14815883.

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.

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).

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.
