Do some code cleanups

When building it with:
	CFLAGS="-Wall -Wstrict-prototypes -Wnested-externs -Werror=missing-prototypes -Werror=implicit-function-declaration -Werror=pointer-arith -Werror=init-self -Werror=format-security -Werror=format=2 -Werror=missing-include-dirs -Werror=return-type"

Lots of warning appear. Clean up the most trivial ones.
