  1. Setup some automated testing if it doesn't exist already.
  2. Do refactoring in small amounts, run the tests and commit the changes before doing more refactoring.
  3. Use "search/replace" tools (`sed`) to help with rewriting common patterns.  Make sure to follow #2 when doing this.
  4. Don't re-organize the code until after most of the unsafe code has been rewritten.  This will allow easier side-by-side comparison with the original C code.
  5. c2rust expands macros and constants from `#define`.  Being able to do side-by-side comparison of the C code will help with adding constants back in and removing expanded code with Rust macros or just normal Rust functions.
