Most of this was generated by the absolutely extraordinary `cargo fix` subcommand. There were still 2 errors and a few warnings to patch up, but compared to the normal 600+ errors, I'd say the fixer did a damn good job! I'm also amazed that I could still start the VM after this, I half expected some kinds of runtime failure...
