Subject: RISC OS SDL Patches

Sam, I've attached a diff of the latest changes to libSDL for RISC OS
support.  These changes are by Alan Buckley and myself.

The most significant of these are:

  Optimised assembler blit rountines - I've attached the file
   src/video/riscos/SDL_riscosASM.s which is needed for this.

  Move to using /dev/dsp instead of its own audio implementation.
  This means that src/audio/riscos/SDL_drenderer.c should be removed

  Typo fixes.  Mainly correct spelling of "RISC OS", but some from elsewhere
  too.
