4f5d3f12f5 audio: Implementation of audio I/O, part II
This patch implements audio I/O for the synchronous, non-MMAP
case.

Updated the StreamDescriptor structure to make it usable.
Clarified comments on the expectations for the client and
the HAL module.

6a4872dff0 audio: Implementation of audio I/O, part I
This patch adds necessary structures and prepares for implementing
data flow for audio I/O.

Also in this patch we clarify the relationship between audio patches
and buffer size for audio I/O, and between buffer size and latency.

00603d14b3 audio HAL: Support for external device connections
Add methods 'IModule.connect/disconnectExternalDevice' which inform
audio HAL about connection / disconnection of an external
non-attached device. Add method 'getAudioRoutesForPort' to
retrieve only routes that include the specified port.

Update the behavior of 'getAudioPorts' and 'getAudioRoutes'
indicating that the result may change due to instantiation
of new device ports for connected external devices.

Clarify behavior of 'IModule.setAudioPortConfig' that it can not
work with device ports with no profiles.

Add debug flags structure 'ModuleDebug' and method
'IModule.setModuleDebug' to control the debugging aspects. VTS
tests use these flags to test HAL behavior which would otherwise
require human intervention.

Update the default implementation and VTS for the AIDL changes.
