/**
 * bitops - bit counting routines
 *
 * These offer convenience wrappers around (and, as necessary,
 * replacements for) the builtin bit testing/counting routines.
 *
 * Example:
 * #include <ccan/bitops/bitops.h>
 * #include <stdio.h>
 *
 * int main(int argc, char *argv[])
 * {
 *	unsigned int v = atoi(argv[1]);
 *
 *	printf("Number of 1 bits: %i\n", bitops_weight32(v));
 *	if (v != 0) {
 *		printf("Least-significant set bit: %i\n", bitops_ls32(v));
 *		printf("Most-significant set bit: %i\n", bitops_hs32(v));
 *		printf("Least-significant clear bit: %i\n", bitops_lc32(v));
 *		printf("Most-significant clear bit: %i\n", bitops_hc32(v));
 *	}
 *	return 0;
 * }
