src/*.c: Add newline between function return type and its name

The purpose of this change is two-fold:
- make function and variable declarations grep-friendly (one can use a
  pattern /^fn_name/ to find the definition);
- make the lines shorter, so less functions need to have their arguments
  span over many lines.

This is more grep-friendly both for finding the function definition, but
also for matching on the return type of the function or the variable.

Update tests/c-lint.sh to enforce this.
