Vendors can have vendor-extended device types and
audio formats supported by their HALs and frameworks.
VTS tests are built using AOSP sources, thus they don't
have these vendor modifications. Ensure that VTS tests
behave correctly when dealing with audio policy manager
configurations that contain vendor extensions.
Since verifying this behavior requires using specially
crafted APM configs, verification is done using
unit tests.

Despite that AUDIO_STREAM_DEFAULT value of audio_stream_type_t
should only used by the framework, it can still end up being
passed to the HAL in port configs and offload info structures.
This happens in the cases when the stream type is not actually
used by the HAL. It seems natural to use an empty string
as the value of AudioStreamType field in this case.

Major challenge: the configuration of HAL tests
depends on the APM XML configuration file which may be
invalid. The code that reads the configuration
has been updated to avoid crashes when the config
is invalid.
In CheckConfig_audioPolicyConfigurationValidation the

a failure to parse the config by the config parser would
lead to the test being skipped, which isn't correct
as it must fail in this case.

This addresses long-standing TODOs in system/audio.h.
Annotated the following enums:
- AudioMicrophoneChannelMapping;
- AudioMicrophoneLocation;
- AudioMicrophoneDirectionality.
This allows removing hand-written conversion functions
since the values are guaranteed to match between HIDL and
system/audio.h.

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.

Enum values defined in the XSD now correspond to the
"no system definitions" lists of enums in
system/media/audio/audio-hal-enums.h.
Added channel masks that used to be in s/m/a/audio-base-utils.h.
Removed use of "vectors of vectors" for channel masks
since individual channels are not allowed to be used
in the APM config and at the HAL transport level.
Fixed definition of the gain mode of audio ports:
1. Since it's a bit mask in the framework, it must be a list in
the audio policy configuration XML file. Note that the old
definition is compatible with the new one as one element is a
valid list.
2. As gain mode is defined in the XSD file, it shouldn't be
defined again in types.hal.

This applies to the following types:
- audio_gain_mode_t;
- audio_flags_mask_t;
- audio_channel_representation_t;
- audio_channel_mask_t;
- audio_devices_t.
Enum types are distinct thus proper overloading on the type
is possible in C++. Also, assignments to enum types are
less prone to errors.

The major change in V7.0 is use of enum values defined
in the Audio Policy Configuration XSD schema. This allows
decoupling types used at the HIDL layer from system/audio.h.
Added a header audio_policy_configuration_V7_0-enums.h
with utility functions analogous to ones from system/audio.h
but defined for the types generated from XSD schema.
Since the code of VTS tests is shared between versions,
ensured that the VTS tests for the previous HAL versions
didn't regress.

This is partial implementation of the example V7.0 audio HAL
which passes VTS tests. Note that the 'core' part
of the HAL (IDevice/IStream) isn't implemented yet.
It passes VTS because it doesn't provide any devices
(modules) and the audio HAL isn't the 'default' instance.

- rename AudioBasicConfig -> AudioConfigBase to better
match a similar structure in audio.h;
- define AudioProfile structure for defining an I/O profile;
- use AudioProfile to replace IStream.getSupported* methods
with a single IStream.getSupportedProfiles method;
- define AudioDevice type for convenience and clarity;
- move enums definition for AudioInputFlags and AudioOutputFlags
into XSD. This allows parsing APM config w/o depending on
the framework code.
