0349c2f03d Introduce Audio V6
Generate with ./newHal.sh 5.0

+ some typo fix in the .hal
+ 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.

Test: push V6 to device and check audio works fine

20614ba604 Audio HAL V5: Introduce HAL V5, equal to V4 for now
find -name 4.0 | xargs -I@ cp -r @ @/../5.0
find 5.0 */5.0 -type f | xargs sed -Ei 's/V4/V5/;s#(@|/)4.0#\15.0#'
find -name *cpp -o -name *.h | xargs sed -i 's/VERSION == 4/VERSION >= 4/g'
mv {4.1,5.0}/config/audio_policy_configuration.xsd

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.

1770b3b44a Audio HAL: Cleanup implementation
Rename files so that, if they are in a X.0 folder, their name does
not contain that version number. That allows for easier copy paste
when creating a new version.

Conversion.h was included from the all-versions instead of the X.0
headers. This in incoherent with the other headers.

Add VersionMacro.h that will be used in the follow up patch.

Also remove shim from VNDK as only stable ABI&API libraries should be
part of it.

8bdafc1b5c Revert "Audio V4: Split system and vendor Audio.h"
This reverts commit 49c56de516.

Reason for revert: Breaks the build of multiple devices

49c56de516 Audio V4: Split system and vendor Audio.h
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.
