Merge branch 'master' into wii-network

# By Ryan Houdek (185) and others
# Via degasus (12) and others
* master: (625 commits)
  Revert "Don't open/close file for every file operation." as it was crashing PokePark in Windows builds.
  Array overrun fixed in VertexShaderCache for the DX11 plugin.
  Fixed DSPTool build.
  Windows build fix
  Go back to assuming every HID device is a wiimote on Windows. Fixed issue 6117. Unfixed issue 6031.
  VideoSoftware: Improve fog range adjustment by using less magic and more comments.
  revert RasterFont for VideoSoftware
  ogl: fix virtual xfb
  Windows build fix from web interface...
  Adjusted the audio loop criteria, using >= on the Wii and == on GC.  This fixes the audio static that occurred in Wii games after hours of play.
  Forced the exception check only for ARAM DMA transfers. Removed the Eternal Darkness boot hack and replaced it with an exception check.
  VideoSoftware: Implement fog range adjustment, fixing issue 6147.
  implement 4xSSAA for OGL
  move ogl-only settings into backend
  Fix description of disable fog, and move it to enhancements tab.
  Reverted rd76ca5783743 as it was made obsolete by r1d550f4496e4.
  Removed the tracking of the FIFO Writes as it was made obsolete by r1d550f4496e4.
  Forced the external exception check to occur sooner by changing the downcount.
  Mark the Direct3D9 backend deprecated.
  Prefer D3D11 and OpenGL over D3D9 by default.
