  Fixed bug 4642 - Rework SDL_netbsdaudio to improve performance
  
  Nia Alarie
  
  The NetBSD audio driver has a few problems. Lots of obsolete code, and extremely bad performance and stuttering.
  
  I have a patch in NetBSD's package system to improve it. This is my attempt to upstream it.
  
  The changes include:
  
  * Removing references to defines which are never used.
  * Using the correct structures for playback and recording, previously they were the wrong way around.
  * Using the correct types ('struct audio_prinfo' in contrast to 'audio_prinfo')
  * Removing the use of non-blocking I/O, as suggested in #3177.
  * Removing workarounds for driver bugs on systems that don't exist or use this driver any more.
  * Removing all usage of SDL_Delay(1)
  * Removing pointless use of AUDIO_INITINFO and tests that expect AUDIO_SETINFO to fail when it can't.
  
  These changes bring its performance in line with the DSP audio driver.
