Result: no hwbinder calls due read / write session.
Added IStream.close method for explicitly freeing up of resources
consumed by the stream before automatic server objects reaping
gets to it.
Test: make, perform Loopback RTT, check traces

Changes made to the .hal definition:
- introduce Effect ID returned by the IEffectsFactory that
needs to be passed to IStream.{add|remove}Effect; otherwise
it's impossible to retrieve the underlying HAL effect handle;
- change "bus address" in DeviceAddress to "string" type;
- fix signature of some methods w.r.t. returning Result;
- remove unused "struct AudioPatch".

Created after hardware/audio.h with the following changes:
- names changed to satisfy HAL style guide;
- defined getter / setter methods for properties, and interfaces
for devices where needed;
- stream out callback changed to be used over RPC;
- 'dump' method is already defined by BBinder, so in HAL
interfaces it is replaced by 'debugDump'.
Note that audio data is currently transferred using byte buffer,
which is not effective due to memory copy and HwBinder transaction
involved. The transfer method will be changed to FastMessageQueue.
