Put `void` in several function prototypes (#387)

I have historically made prototypes for argument-less functions
 with just plain `()` for the argument list. This has caused some
 minor pains when using `m2c` and is, pendatically, incorrect.

So I have changed all argument-less function protoypes to instead
 have `(void)` as the argument list. This required a couple small
 fixes here and there.
