Changes: Implement software surround downmixing (fix #796). Fix a crash when no audio renderer were created when stopping emulation. NOTE: This PR also disable support of 5.1 surround on the OpenAL backend as we cannot detect if the hardware directly support it. (the downmixing applied by OpenAL on Windows is terribly slow)
