Fixed directsound PaDeviceInfo default latency and PaStreamInfo latency fields. Fixed host buffer size calculations based on suggestedLatency parameters. Switched to using 48kHz as default sample rate when other info isn't available. Fixed edge case in TimeSlice() where a full duplex stream could read data even though either input or output reported zero bytes available. Renamed some variables for clarity. Fixes ticket #160 (PaStreamInfo latency). Addresses #122 (although we're still using old default latency values from V18 codebase). Addresses #99 (correct interpretation of suggestedLatency down to zero).

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

Replaced MM timer with a high priority thread for audio compute, based on a patch by Dmitry Kostjuchenko. Reason: there is one global MM timer thread per process and doing audio compute in it was interfering with timer accuracy and also with running multiple DSound streams. The old MM timer based implementation is still available if you define PA_WIN_DS_USE_WMME_TIMER -- this may be removed in future.
