* changes:
Use PassthruPatchRecord for DIRECT to DIRECT connections
Add PassthruPatchRecord for low latency software patches
Abstract access to HAL stream via Source in RecordThread
Move PlaybackThread::Track::writeFrames to PatchRecord
When both input and output connected by a software patch
are in 'DIRECT' mode (no framework processing), use
PassthruPatchRecord as it helps to reduce the latency
significantly by avoiding intermediate buffering.
Remove 'std::nothrow' from tracks creation in PatchPanel
for consistency with other code.

Implement a subclass of PatchRecord that uses PatchTrack's
thread for reading from HAL. This eliminates the need for
buffering that adds latency.
The only modification needed for PatchTrack is to indicate
unlimited amount of available frames to the playback thread.
This is to prevent PatchTrack from being deactivated by
DirectOutputThread due to lack of frames available.
RecordThread believes it reads audio data on its thread,
and manages timestamps as usual. The data that it "reads"
and passes to PassthruPatchRecord is discarded by the latter.

This allows to replace direct reading from HAL with obtaining
audio data from another source.
It should be possible to encapsulate reading from FastCapture
in the same manner, but it's not required for direct inputs.

This code logically belongs to PatchRecord because it emulates
obtaining recorded data from a client.

The error must not be ignored as otherwise the Java layer
thinks that recording has started successfully.

First test for audio health check. The test checks if all declared
devices found by checking if the audio device types of attached devices
can be seen by audio policy.

The deprecated method AudioManager.isBluetoothA2dpOn() calls
getDeviceConnectionState on APM with an empty address, which
caused HwModuleCollection::getDeviceDescriptor to set an empty
address on the DeviceDescriptor for the currently connected
A2DP device. This method is called by MediaRouter.
When the address was reset, the java listener for audio device
connection monitoring was reporting the connection of an A2DP
device with an empty address, which in turn caused AvrcpManager
to behave as if the audio device connection failed.
If MediaRouter called isBluetoothA2dpOn() before AvrcpManager
received its called for device connection, the error would occur.

Android provides 2 audio policy engines:
libaudiopolicyenginedefault and
libaudiopolicyengineconfigurable. This change makes the engine
to be loaded dynamically based on the configuration (currently
the engine name is hardcoded into AudioPolicyConfig). Dynamic
loading allows building and installing of both libraries without
any conflicts.
Technical changes:
- AudioPolicyManagerInterface renamed to EngineInterface
for clarity;
- For the purpose of dynamic loading, APM does not depend
anymore on the EngineInstance class. The class got removed
from the default AP engine, but left in the configurable engine
because it is also used by its plugins;
- Added EngineLibrary class to encapsulate dynamic loading
of the AP engine. The class name EngineInstance is repurposed
for a smart pointer to EngineInterface;
- services/audiopolicy/managerdefault/Android.mk converted
into Android.bp;
- Added engine loading failure test;
