Modified Files:
	syssrc/sys/ufs/ffs: fs.h

Log Message:
More fixes from FreeBSD (with changes):
- Cast blk argument to lblktosize() to (off_t), to prevent 32 bit overflow.
  whilst almost every use in ffs used this for small blknos, there are
  potential issues, and it's safer this way.  (as discussed with chuq)
- Use 64bit (off_t) math to calculate if we have hit our freespace() limit.
  Necessary for coherent results on filesystems bigger than 0.5Tb.
- Use lblktosize() in blksize() and dblksize(), to make it obvious what's
  happening
- Remove sblksize() - nothing uses it
