Pre-flight check

[Timidger]

This is a list of things to double check and sign off on before 1.0.

• Implement Copy on everything that's reasonable.
• Implement Clone on everything that's reasonable.
• Implement Hash, Eq, PartialEq, Debug, and Display on everything.
• Document every model.
• Document every public structure.
• Document every public function.
• Run a (stable) rustfmt on the codebase.
• Run clippy on the codebase and fix all warnings.
  • Pre-pre-check: Configure clippy.
• Allow (unsafe) raw access of every structure so the user can access things we don't expose safely
  • This means that, with some exceptions, we don't have to re-export unsafe fields or functions and can simply let the user access them by using the raw pointer. Terms and conditions apply, check inside the codebase for more details.
• Look at the header files for every file and ensure every function and field is accessible:
• Ensure builds on *BSD.
  • Might need to add meson build -D b_lundef=false.
• Add unstable build flag.
• No TODOs or FIXMEs (enforced by build server).
• Ensure C types are used to proprely encode architecture specific types (e.g. int, double, etc.)
