This splits headers into three locations:
include - for backwards compatibility, the global include
include_all - for things system/vendor both use
include_vendor - for things that only vendors use
The goal is to gradually have system things stop referencing
(at least most) of these headers.

Add a function to audio HAL interface for retrieving audio_port_v7
structure directly. The legacy audio_port structure can always be
converted into audio_port_v7, however the latter may contain more
information.
This function must be supported from legacy HAL version 3.2.

Add a function to audio HAL interface allowing the attachement of an
audio effect to an audio device.
This is used when an audio effect is implemented below the HAL (e.g by an audio DSP)
and is attached/enabled when a particular sink(e.g speaker) or source(e.g mic) device
is selected.
This function must be supported from legacy HAL version 3.1.

audio.h and its dependencies (audio-effect.h, sound_trigger.h...)
used to be shared between system and vendor code.
This led to multiple problems:
1) Such sharing contradicts the Treble policy of
strict independence of framework and vendor code.
2) When audio.h was changed, every vendor needed to update
its code in the next release. This meant that audio*.h
headers were mostly changed in backward compatible manner.
Nevertheless, for P the HIDL interface and thus the audio.h
interface are changed in backward incompatible way.
(Some enum are becoming 64 bit long).
3) As the headers were common, some API used only by the framework
needed to be visible to the vendors (mostly enum values).
4) Treble policy is to support at least one previous HAL version
As a result the audio*.h headers are now duplicated,
one set for the framework, and one for the vendor.
Each set will evolve independently. After this split,
the framework-only APIs will be removed from the vendor headers
and vice versa.
The split is implements as such:
+ for system code
- NOT moving the libaudio_system_headers
Eg: system/audio.h and system/audio_effects/effect_equalizer.h
are still in system/media/audio
- the legacy audio HAL API that were in libhardware headers
are now in libaudiohal_legacy_headers
Eg: hardware/audio.h and hardware/audio_effect.h
are now in frameworks/av/media/libaudiohal/legacy/
+ for vendor code
- moving libaudio_system_headers and the legacy audio HAL API
that were in libhardware_headers in
android.hardware.audio.common.legacy@2.0
Note that those headers are now versioned, so migrating to a @4.0
HIDL HAL will mean changing the legacy dependency too.
Eg: system/audio.h, system/audio-effect.h, hardware/audio.h
are now in hardware/interfaces/audio/common/2.0/legacy
- the legacy audio effect HAL API that was in libaudioeffects
is now moved in android.hardware.audio.effect.legacy@2.0
Eg: audio_effects/effect*.h are now in
hardware/interfaces/audio/effect/2.0/legacy
- the legacy sound trigger HAL API that were in libhardware_headers
is now moved in android.hardware.soundtrigger.legacy@2.0
Eg: hardware/sound_trigger.h is now in
hardware/interfaces/audio/effect/2.0/legacy
libaudioutil being used by both system and vendor, had
to be renamed for system to libaudioutil_system.
Vendor libs that now depend on the audio.h of a specific
version and are not extensively referenced in non google code,
append @2.0 to their name.
Note that headers that are not expected to change in the 4.0 HAL are
left in all-versions folder to avoid duplication.
This is an implementation detail as the versioned libraries export
the all-versions headers.
Note that strict vendor-system separation is enforced by the
build-system. The system headers are not available for vendor
libs and vice-versa.
Note that this patch is split between numerous git repository (>10),
all the commits having the same Change-id for searchability.
Note that audio_policy.h is no longer exposed to vendors
as the legacy audio policy HAL API was never officially supported.
As a result the audiopolicy stub implementation has been removed.

The names of the modules are also used in audio policy configuration
files and thus need to be consistent between HAL and the framework.

The HW A/V sync ID is retrieved from the HAL by calling
global get_parameters() with key AUDIO_PARAMETER_HW_AV_SYNC.
After the output stream is opened, the HW A/V sync ID is communicated
by stream set_parameters() with key AUDIO_PARAMETER_STREAM_HW_AV_SYNC.

Pass device address (and audio source for inputs) to
open_output_stream() and open_input_stream() audio HAL functions.
Bug: 14815883.
Change-Id: I5535677db3f3027917a31a7ed5c0a4c6bc013639
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.

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).
