Minor cleanups: unused vars, unreachable code, static globals.

- All global variables should be static unless they have an explicit
  extern declaration in a header file.
- `to_compare` was not used in encryptsave and toxav tests.
- `break` in switch cases is not required directly after `return`,
  `goto`, or a noreturn function like `abort`.
