[sldev] OpenAL patch updated

[Callum Lerwick]

Alright, I finally got a chance to sit down and do some debugging on my
wife's x86_64 laptop. Turns out the crashyness was caused by not having
stub implementations of all the audio streaming calls, which only
affected x86_64 for some reason. There's still a bit of crashyness,
which I just realized is probably because I need to make stubs for the
wind noise calls too. Turning the wind volume slider all the way down
seems to avoid it.

I managed to fix the problems with doppler. Near as I can tell the sense
of scale in SL is just plain off, so I scale the doppler factor down by
a factor of 100 (!) which brings it down to a reasonable level. I tried
scaling the speed of sound up instead, but that caused overflows inside
OpenAL... I haven't bothered doing any comparison with fmod so I don't
know how this matches up with what fmod is doing.
