7d01538eec Audio HAL V7.1: Update the default implementation
Split versions of "common" and "core" types from
the version of the interfaces. "Common" and "core"
versions are set to 7.0.

Implemented new methods of V7.1 interfaces.

5ec48c2d4d audio: Create libraries for data types in core and effect
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.

ff611980f3 audio: Update common types to better match legacy structs
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.

f363ed4f96 audio: Update default effect HAL wrapper to support V7
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.

532240f4eb Audio HAL: Fix UAF if the effect is removed after close
Effect::close in V6 releases the underlying HAL effect.
It was not removing the effect entry from the effects
map, thus a call to Stream::removeEffect was retrieving
a stale handle.

d041930df9 Audio V6 wrapper: IDevice|IStream|IEffect.close releases HAL resource
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.

fa02144f8d audio: Add support for dumping info from effect HAL modules

debugging info into the provided file descriptor (same model
as used for devices and streams).

00a44c0fc2 Audio HAL: More generalization for types imports
Complement imports of audio::CPP_VERSION with audio::common::CPP_VERSION
for core.

Import namespaces in VTS tests.

Remove "using namespace" from .cpp files where there
are already imports in the .h file.

Test: try moving types between audio/types.hal and common/types.hal.

3907f767d9 Audio HAL: Simplify types updates for 'common' and 'effect' packages
Instead of importing every single type individually ("using <type>"),
import entire namespaces of
::android::hardware::audio::common::CPP_VERSION and
::android::hardware::audio::effect::CPP_VERSION
inside the "implementation" namespace in the default implementation.

This simplifies modifying types, as it is not needed anymore
to surround "using <type>" directives with #if MAJOR_VERSION ...

Note that the contents of the namespaces are imported inside
the "implementation" namespace, which reduces risks of name collision
