Plumb the notification about audio HAL services update to APM
libaudiohal: Allow late registration of HIDL HAL services
Allow for late audio module discovery in APM
DevicesFactoryHalHidl registers a notification callback
with a service manager to get notified about registration
of new HAL services.
The specific code for the MSD HAL has been removed,
this HAL service is now handled using the added generic
mechanism.

When creating native audio track, a IAudioTrackCallback will be created
systematically. All callbacks will be cached in Threads and protected by
a lock. Whenever there is a callback event from audio HAL, it will
finally trigger callback to native audio track. Currently, there is only
one callback event, which is codec format change.

Remove static linking to libaudiohal@N.0.so libraries.
Instead, use HIDL IServiceManager to figure out the actual
version used by the device and load the appropriate library
dynamically.

Add management of audio effects applied to a specific input
or output audio device.
A new class DeviceEffectProxy derived from Effectbase is added
to represent an effect attached to a particular audio device type and
address. This proxy manages one or more actual EffectModule instances
automatically added to a playback or capture thread or directly to the
audio HAL when the targeted audio device is used by an audio patch.
A new DeviceEffectManager class is added to manage creation and release
of DeviceEffectProxy instances and monitor creation and release of audio
patches and create or release actual effect instances accordingly.

management it's better to have it defined at all layers.

Refactor interface between audio flinger and audio policy. Use device
descriptor instead of audio device type and address. DeviceDescriptor
can contain more information that may be useful when opening an output
stream.
In audio policy, if multiple audio devices are passed in when opening
an output stream, one device is extracted using the same strategy as
when selecting a device for volume application. When starting source,
audio policy manager will call audio flinger to create audio patch. In
that case, multiple devices will still be patched to the output stream.

Move ExtendedAudioBufferProvider.h to libaudioclient. This is
a more appropriate location because EABP extends AudioBufferProvider.
Move SingleStateQueue.h to libnbaio_mono. This is a more appropriate
location because SSQ is a non-blocking queue.
This allows to remove the dependency of libnbaio on libmedia
which is a good thing because libnbaio provides more low-level
abstractions than libmedia.
Also, replace a dependency of libnbaio on libbinder with
a dependency on libaudiohal header library.

Add workaround for missing patch handle in HIDL
interface createAudioPatch() method signature.
The legacy HAL implementation has the convention of releasing
previous audio patch when a valid patch handle is passed.
The framework relies on this optimization and does not release previous
patch explicitly when just updating the sinks of an existing patch.

Using 'exit' from an RPC threadpool thread is not safe, as 'exit'
runs atexit handlers that destroy global objects. This can interfere
with code still running on other threads.
'_exit' does not run atexit handlers, just terminates the process.

(cherry picked from commit 5beb481006)
(cherry picked from commit 06c5d53533)
When opening an input stream for a software patch, pass in
the downstream destination device info. This helps the intermediate
module to set up any device-specific processing.
Note that the intermediate module must implement Audio HAL V5.0
in order to be able to receive this information. It's not available
on the legacy audio HAL API either.
