Cleanup of bitstring.h: 1) Add FreeBSD: tag. 2) Add parenthesis around macro args. 3) Add parenthesis around macros which are expressions. 4) Add do { ... } while (0) around macros which are compound statements. 5) Sync bitstr_size and bit_alloc with neater versions from NetBSD. 6) Fix bit_ffs and bit_ffc so that they don't search off the end of the bitstirng. 7) Try to avoid rightshifting signed ints. I didn't take NetBSD's version directly as the macros are significantly slower for long bitstrings. Bruce reviewed a previous version of this patch.
