Abstract away access to audio streams HAL in AudioFlinger
In this CL all direct access to audio_stream_t, audio_stream_out_t, and
audio_stream_in_t their functions is encapsulated within the new
hierarchy of Stream[In|Out]HalLocal classes. AudioFlinger uses
interface classes Stream[In|Out]HalInterface to access these functions.
Note that NBAIO still receives raw HAL stream handles and needs to be
converted separately.

Test: manual with Loopback app

Abstract away access to audio devices HAL
In this CL all direct access to audio_hw_device_t and its functions is
encapsulated within the new class DeviceHalLocal. Loading of hardware
modules is encapsulated withing DevicesFactoryHalLocal. AudioFlinger
uses interface classes DevicesFactoryHalInterface and DeviceHalInterface
to access these functions.

Remove self-recursive includes from AudioStreamOut.h and SpdifStreamOut.h
These includes do not make much harm but look confusing.

AudioTrack: support ENCODING_IEC61937
Set DIRECT flag.
Use audio_has_proportional_frames() instead of audio_is_linear_pcm()
where appropriate.

AudioFlinger: fix repeated underruns for compressed audio
The AudioFlinger kept pausing the audio when playing compressed AC3 or DTS.
This caused pause/resume loops that were hard to break out of.
The AudioFlinger was thinking that the compressed audio was PCM
because the HAL was in PCM mode playing SPDIF data bursts.
It also thought that EAC3 was at 192000 Hz instead of 48000
Hz because the data bursts are played at a higher rate.
This CL adds more calls to the shim that separates the AudioFlinger.
Now the AudioFlinger gets information about the HAL sample rate,
channel masks and format from the shim instead of calling the HAL directly.
The AudioFlinger now uses a different threshold for detecting
underruns when the audio is compressed.

AudioFlinger: reset frame position on standby
The HAL does not reset the frame position on standby().
But applications expect the frame position to be reset.
So we subtract the position at standby from the current position.

AudioFlinger: call SPDIF wrapper from AudioFlinger
Create an interface layer between the AudioFlinger and the HAL
that manages the wrapping and format conversion.
Removed unnecessary includes.
Handle rate conversion in getRenderPosition().
Try to open HAL with encoded format before wrapping with SPDIF.
