moved memory barriers as per this thread: http://music.columbia.edu/pipermail/portaudio/2011-August/012803.html . use volatile because MSVC Read/WriteBarrier() intrinsics are just compiler barriers, but MSVC will insert memory barriers if you use volatile. see: http://msdn.microsoft.com/en-us/library/ms686355(VS.85).aspx

disable dither conversion when host input format is 32 bit and user format is 24 bit. the converter for this is unimplemented anyway, and the host won't ever be sending us better than 24 bit data, so no need to dither it.

Commit fix for crash during full-duplex operation with PulseAudio. Reported by Al Dimond, fix proposed by Ross Bencina, acked by Dmitry Kostjuchenko. This fixes a bug with Dmitry's zero-copy optimisations. Fix works in Audacity (where the bug was found), so comitting upstream.
