Halo: Combat Evolved — decompiling Xbox build 2342

This is a work-in-progress decompilation of Halo: Combat Evolved build 2342. The executable is cachebeta.exe, SHA-256 4cc87b45f721270392a96f1674ed2b5cd4a7bb4355faeab4531d1cf1884d9520, from the PAL debug build. The August 2001 Xbox SDK supplies xbox/bin and xbox/include. configure.py prepares the build. ninja build compiles it and prints progress. On Windows, projects/cachebeta.sln opens in Visual Studio 2022. The README says later Halo debug symbols are used to map types, and that the CEA beta is not identical to the Xbox game.
