Added audio HAL functions to control audio routing and audio gain.
Audio HALs above version 3.0 must implement these functions.
These functions will be used by the framework instead of
out_set_parameters("routing"=XXX) for device selection on an output
or input stream.
They will also allow direct connection of input devices to output devices
as well as gain control on devices or streams.
The gain or routing capabilities are exposed in audio_polciy.conf file.

Inheritance of HAL object is performed by composing a child structure of a
single parent structure located at offset 0 followed by new data members
and function pointers in the child structure.
For example,
struct child {
struct parent common;
int a_data_member;
void (*a_method)(struct child *c, int v);
};
HAL code assumes this layout when accessing child structures given a pointer
to a parent structure such that users write code like the following...
void child_method(struct *parent, int v) {
struct child * c = (struct child*)parent;
// do stuff with c
}
Code above will break if a member is added before "common" in "struct child".
This change adds comments that describe the restriction on the location of
parent HAL objects within a derived HAL object. HAL objects that already
have comments that describe the required location of parent objects are not
modified.

- Add non-blocking write support, set_callback() function
- Add pause, resume, flush, drain functions to audio output stream
- Add audio parameter defines for compressed audio metadata
- Extend audio_config_t to include an audio_offload_info_t field
- Add is_offload_supported() function to test whether there is
hardware decode support for a given compressed audio format
- Change audio_stream_frame_size() to handle offloaded streams.
For an offloaded stream the size is always counted in bytes
(frame size == 1) and the number of channels is irrelevant.

Changed audio device API version to 2.0 because of
new enums for audio input and output devices.
Removed implementations of get_supported_devices() in
stub and usb audio modules.

New definitions of audio devices for remote submix: one representing
a sink for writing the audio buffers that won't be played directly
locally, another representing the audio source that can be read from
to obtain the audio mix.
New audio hardware module encapsulating the submix loop functionality.
Create a Pipe to serve as non-blocking audio ring buffer between
the output device (the sink) and the input device (the source).

Modified open output and input stream functions to add new
parameters needed by audio HAL. Also grouped parameters
in a config structure for clarity.

Fill out a missing entry in the audio HAL function table.
The entry for get_initial_master_volume was missing from the non-legacy audio
HAL and needs to be filled out. Also fix up the order of the comments
describing the get_initial_master_volume method.
