OpenGL adaptation of n64decomp/sm64.

Feel free to report bugs and contribute, but remember, there must be no upload of any copyrighted asset. Run ./extract-assets.py --clean && make clean or make distclean to remove ROM-originated content. This port has been made possible thanks to n64-fast32-engine by Emill.

• Native rendering. You can now play SM64 without the need of an emulator.
• Variable aspect ratio and resolution. The game can now correctly render at basically any window size.
• Native xinput controller support. On Linux, DualShock 4 has been confirmed to work plug-and-play.
• Analog camera control and mouse look. (Activate with make BETTERCAMERA=1.)

Do NOT attempt to compile Windows executables with WINDOWS_BUILD=1 under Linux or WSL. It will NOT work. Follow the guide on the wiki.
