AudioFlinger: tell HAL the PCM is non-audio
Add a bit to tell the HAL that the PCM data is really encoded audio
wrapped in a data burst.
Otherwise the device may try to play the encoded data directly
which will sound like modulated white noise.

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.
