Subject: audio: move some fallback handling to common AO reload function

Now a reload requested by an AO behaves in exactly the same way as
changing an AO-related options (like --audio-channels or
--audio-exclusive). This is good for testing and uniform behavior. (You
could go as far as saying it's a necessity, because the spotty and
obscure AO reload behavior is hard to reproduce and thus hard to test at
all.)
