d3d10umd,d3d10sw: Initial import. 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%. Known limitations: - TGSI (no NIR) - D3D10 only (no D3D11 support yet) - no WINE integration (WINE doesn't implement WDDM DDI.) For further details see: - src/gallium/frontends/d3d10umd/README.md - src/gallium/targets/d3d10sw/README.md v2: Drop the DXBC-based disassembly. Add missing break statements. v3: Incorporate Jesse's feedback.
