Remove various redundant declarations. Instruct lex not to generate code which isn't going to be used, thus avoiding some unused function warnings. Note that bison <2.5 expects stdlib.h to define _STDLIB_H if it's been included, and avoids prototyping free/malloc in that case. Some stdlib.h (e.g. newlib) may not match precisely (e.g. defining _STDLIB_H_), so we define it after including stdlib.h to be sure, and avoid a redudant declaration warning for those symbols.
