Rename LinuxAudioError to OSSAudioError ('ossaudiodev.error').
Rename LinuxAudioError to OSSAudioError ('ossaudiodev.error').

Use OSSAudioError much less frequently -- all real I/O errors (ie. any
time open(), read(), write(), ioctl(), or select() return an error)
become IOError.  OSSAudioError is only used now for bad open() mode.
