This will allow vendors to create instances of
this library with other names. A different name
is required if a vendor wants to provide a custom
version (e.g. in HIDL) of
android.hardware.audio@6.0-impl and still
be able to use the library itself (e.g. to load
audio.r_submix.default) -
android.hardware.audio.service does not load both
libraries and prefers the default one.

It is suggested to do so according to Vector.h and SortedVector.h.
At framework side, there are audio containers such as FormatVector,
ChannelMaskSet, SampleRateSet to replace the usage of Vector
SortedVector for audio stuff. In default hal implementation, we can
use these audio containers to replace Vector and SortedVector.

Generate with ./newHal.sh 5.0

+ some clang-tidy run
This new HAL is an exact copy of the V5.
It will be modified in following patches while R is developed.

Then a manual update to Android.bp to add V5 support.
Then a manual update to service.cpp to add support for loading 5.0.
If someone knows a way to avoid copying the .hal, it would be great.
They will be 99% identical between V4 and V5.

All the new files added are a copy of the 2.0 ones, with just the
version 2 that was changed to 4.
Due to the rollback on the retrocompatiblity breakage,
the split of implementation is not strictly needed any more.
This makes the current split in .impl.h and double include
unnecessary complicated.
This will need to be factorized in a future patch.

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.
