This change adds a gallium D3D10 state tracker that works as a WDDM UMD software driver, similar to Microsoft WARP, but using llvmpipe/softpipe.
The final deliverable is a d3d10sw.dll, which is similar to WARP's d3d10warp.dll.
This has been used to run Microsoft Windows HCK wgf11* tests with llvmpipe, and they were at one point passing 100%.
- TGSI (no NIR)
- D3D10 only (no D3D11 support yet)
- no WINE integration (WINE doesn't implement WDDM DDI.)

XXX: This depends upon Windows DDK drivers being placed on mesa/include/winddk. A version of these which builds with MinGW can be found on here. Ideally we'd use headers from the actual WDK on Windows.
