augustss 6616d47838 - Change audio_hw_if a little: set_param now sets the play and record modes
at the same time instead by using two different calls.  This enables
  it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
  play and record settings are independent.
- Fix some buglets in audio.c.

/*
* Software state, per SoundBlaster card.
* The soundblaster has multiple functionality, which we must demultiplex.
* One approach is to have one major device number for the soundblaster card,
* and use different minor numbers to indicate which hardware function
* we want. This would make for one large driver. Instead our approach
* is to partition the design into a set of drivers that share an underlying
* piece of hardware. Most things are hard to share, for example, the audio
* and midi ports. For audio, we might want to mix two processes' signals,
* and for midi we might want to merge streams (this is hard due to
* running status). Moreover, we should be able to re-use the high-level
* modules with other kinds of hardware. In this module, we only handle the
* most basic communications with the sb card.
