Wine Staging 1.7.55

Wine Staging is a testbed Wine compilation with new experimental features and application bug fixes (formerly known as wine-compholio). It's synced with regular Wine, and patches sent upstream after testing. There are for example CSMT, or CUDA/PhysX support, DXVA2 GPU video decoding, Job Object support, named pipe message mode, IO performance optimizations, S3/DXTn support, the threadpool API, d3dx9 improvements, Windows ACL support, and a PulseAudio driver for Wine.
