sync up libossaudio with NetBSD changes.

--
- Add __BEGIN_DECLS & __END_DECLS for C++
- Make protection against multiple inclusion non-invasive wrt. name space
- Use EAGAIN instead of EWOULDBLOCK.  The actual numeric value is
same, but EAGAIN is the posixly correct name
- Remove white space
- Change the behaviour to report emulated encodings, too
- Implement SOUND_MIXER_INFO
- Implement OSS_GETVERSION
- Accept mixer values above max (100)
- Handle the info from AUDIO_MIXER_DEVINFO properly, parts of it is opaque
- Use accurate rounding in conversion between OSS and OpenBSD volume values
- Map OSS mixer device "line1" to native mixer device "aux"
