Support collaborative audio focus handling
Add new flag for an app to define it doesn't duck, but rather
pauses when losing focus with AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK.
This flag is to be used when requesting focus.
Add support for AudioPolicy to specify whether it will implement
ducking itself, rather than it being handled by an app.
When ducking is handled by a policy, do not notify focus owners
when they lose audio focus with LOSS_TRANSIENT_CAN_DUCK, unless
they would have paused, as expressed with the
AUDIOFOCUS_FLAG_PAUSES_ON_DUCKABLE_LOSS flag.
Add a focus listener for a policy to be notified of focus changes
so it can properly implement its own ducking.

AudioMix address and type, rule exclusion API, dynamic source
- Simplify API for defining an exclusion-based rule: don't define
an exclusion rule, add instead a way to exclude a rule.
- API for defining rules for dynamic sources (rule match on capture
preset).
- Verify mix type when creating AudioRecord or AudioTrack for a mix.
- Use hashcode of mix for generating the device address.
- AudioService dump prints info about registered policies.
- Annotate as SystemApi the audio policy-related APIs.
- Express mixing match and exclude rule constants as flags for
future-proofness

Convert record channel mask for dynamic mix
When creating the AudioRecord instance for a dynamic mix, convert
the output channel mask of the mix to an input channel mask
to be used by the AudioRecord instance through which the
mixed audio is rerouted.

More AudioPolicy registration
Define new usage in AudioAttributes to describe "virtual" sources.
Maintain a registration string in AudioPolicy and AudioMix that
is used for the address of the mix in the native policy manager.
AudioPolicy registration marks the audio policy configuration and
the audio mixes as registered.
The AudioPolicy class is used as the factory for the AudioTrack
and AudioRecord objects that are respectively used as the
source and sink of the mixes created by the policy owner.

Define audio policy, mixes, and mixing rules
An AudioMixingRule is a collection of AudioAttributes and match/exclude
rules.
An AudioMix is defined by its AudioMixingRule, AudioFormat and
routing flag.
An AudioPolicyConfig is a collection of AudioMix and is
parcellable.
An AudioPolicy has an AudioPolicyConfig, and
can be registered/unregistered through AudioManager.
