Log:
[AUDIO-BRINGUP]
- More fixes for mmixer library
- Store destination lines sharing the same mixer object in the same object
- Fix generating destination lines id / soure lines
- Add mux node for input mixers
- Disable code which checked if the topology node has already been reserved for an another
line. Tests in WinXP concluded that ms does not do this at all, though documentation
claims it
- Add source line to the correct destination line
- Fix a memory leak
- Fix tons of bugs in MMixerGetLineInfo
