/**
 * structeq - bitwise comparison of structs.
 *
 * This is a replacement for memcmp, which checks the argument types are the
 * same, and takes into account padding in the structure.  When there is no
 * padding, it becomes a memcmp at compile time (assuming a
 * constant-optimizing compiler).

 * Example:
 *	#include <ccan/structeq/structeq.h>
 *	#include <ccan/build_assert/build_assert.h>
 *	#include <assert.h>
 *	
 *	struct mydata {
 *		int start, end;
 *	};
 *	// Defines mydata_eq(a, b)
 *	STRUCTEQ_DEF(mydata, 0, start, end);
 *	
 *	int main(void)
 *	{
 *		struct mydata a, b;
 *	
 *		a.start = 100;
 *		a.end = 101;
 *	
 *		// They are equal.
 *		assert(mydata_eq(&a, &b));
 *	
 *		b.end++;
 *		// Now they are not.
 *		assert(!mydata_eq(&a, &b));
 *	
 *		return 0;
