Add APis for controlling the latency mode on an output stream.
Latency mode control is optional but mandated if spatial audio with
head tracking is supported over Bluetooth classic audio link.

versions are set to 7.0.

Add 'CoreUtils' library similar to 'HidlUtils' for the types
specific to the core HAL. Add 'EffectUtils' library similar to
'HidlUtils' for the types specific to the effects HAL. Move into
them and de-duplicate code previously scattered across the
default HAL implementation and libaudiohal. Add unit tests.
Removed 'AUDIO_{INPUT|OUTPUT}_FLAG_NONE' from the list of
values in the XSD file to avoid additional complexity due to
equivalence of this value to an empty list of flags.

HAL V7 types were updated to better match data structure
definitions from the legacy HAL:
- Added 'AudioConfigBaseOptional' struct to match
legacy structs that have 'mask' field to specify
initialized fields.
- All fields in 'AudioConfigBase' made mandatory.
- Removed 'EffectConfigParameters' in favor of
'AudioConfigBaseOptional' and safe_unions.
- Added missing enum string values to ensure that round-trip
conversions from the legacy HAL to HIDL and back to legacy
preserve enum values.

wrapper.
Interface updates:
- Update AudioConfig structure to indicate whether
AudioOffloadInfo is specified.
- Add return value to IStreamIn.updateSinkMetadata

of invalid arguments.

During this conversion, the functionality of the V7 wrapper
hasn't been tested yet. This will be done in a separate CL
that will also include required updates to the VTS tests.
Since the changes were made to the code shared with pre-V7
versions, verified that V6 HAL didn't regress.

Major change: audio-base.h is generated from "core" types.hal,
new file audio_common-base.h is generated from "common" types.hal.
In order to be able to add system-only constants to generated
enums, the latter are made anonymous, values got "HAL_" prefix.
Then in system/audio.h a full enum is constructed.
Removed audio_drain_type_t from exported, as it belongs to
libhardware only.
Added missing enums that were introduced at the system side
only in Android R.

of audio streams optionally preserving the pitch (this is
often referred to as "timestretch"). HALs can apply these
parameters when decoding of streams is done in hardware.

Some methods of legacy HALs are optional. The legacy HAL
can avoid implementing them either by setting the function
entry in the interface table to NULL or by setting it
to a stub function returning -ENOSYS. In the latter case
the default implementation was spamming syslog with
warnings. Specify that ENOSYS returned from optional legacy
HAL methods must be ignored.

Fixed behavior of IStream|IEffect.close to release the underlying
HAL resource synchronously. This is to avoid adding artificial
delays in VTS that become totally unpractical in V6.
Added clarification about expected client behavior for
IStream|IEffect.close w.r.t. audio data transfer.
Added IDevice.close method which releases HAL device resource.
Updated VTS tests to remove delays in V6.
