Style improvements:

 - Sort function prototypes;
 - Apply static on all function bodies.  To quote bde@:

> It is a good obfuscation to declare functions as static only in the
> prototype, so that you can't see the static for the actual function.
> The reverse obfuscation (with static only in the function definition)
> would make more sense, but is a constraint error.
