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".

Changes made to the .hal definition:
- added missing generated Result for methods implemented via legacy
"command" function;
- fixed Aux Channels feature definition;
- added "size" parameter for reply data in cases where the wrapper
needs to allocate a reply buffer;
- added method for generic support of feature configs;
- added new Result type;
- use arrays instead of strings in effect descriptor to ease
conversion from / to legacy HAL;
- added missing method to the Preset Reverb interface;
- fixed names of the Visualizer enums to avoid clashes with defines
from the legacy HAL file.
The implementation isn't hooked up to the server yet. Need to implement
devices and streams first.
