  Modified files:
    include              bitstring.h 
  Log:
  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.
