ao_oss: remove this audio output
Ancient Linux audio output. Apparently it survived until now, because some BSDs (but not all) had use of this. But these should work with ao_sdl or ao_openal too (that's why these AOs exist after all). ao_oss itself has the problem that it's virtually unmaintainable from my point of view due to all the subtle (or non-subtle) difference. Look at the ifdef mess and the multiple code paths (that shouldn't exist) in the removed source code.

See ``--ao=help`` for a list of compiled-in audio output drivers. The

driver ``--ao=alsa`` is preferred. ``--ao=pulse`` is preferred on systems

may work (the latter being experimental).

Sets the audio mixer channel (default: ``pcm``). Other valid values

include **vol, pcm, line**. For a complete list of options look for
