AdvanceMAME v3.1

• Added support for SDL2. It's the new default in Linux and Windows.
  This results in better performance and better VSync support
  when running in a window manager environment like X Window
  or Windows. It also enables again the RGB effects.
  The exception is Raspberry where SDL1 still provides better
  performance in the X Window environment, and it's still the
  default option.
• More reliable Raspberry video mode setting when using programmable
  modes. It now uses the Raspberry VideoCore libraries to
  control better the system.
• More precise VSync syncronization, avoiding any missing frame.
• In MESS fixed the loading of disk image for the TI99-4A system.
• In MAME marked 'retofinv', 'svc', 'prmrsocr' and 'viostorm' as not
  working to trigger the use of the working clones.
  Also added the game 'mp_shnb3'.
• Fixed the UI flickering and a potential crash when SMP is active.
• The Linux joystick event and raw interface now support up to 32
  button. Before it was only 12.
• If SMP is active, don't automatically disable the resize
  effect if the game is too slow. This gives a more
  stable 'auto' effect.
• Changed the 'sync_resample auto' to be 'emulation' instead
  of 'internal'. This give more stable sound when
  the game emulation is too slow.
• The 'display_magnify auto' option now takes into account
  the monitor limits to avoid over scaling.
• Restored the functionality of "-output fullscreen" option.
  It wasn't able anymore to find video modes.
• Added support running from a SSH shell.
• Removed the 'lq' effect. It was not really used.
  The 'scale2x' and 'scale2k' are faster and better.
• The RunClone menu now excludes preliminary clones if they
  are already filtered out in the main list.
