History
Bruce Evans ccb174975a Fixed lblktosize(). It overflowed at 2G. This bug only affected 
ufs_read() and ufs_write().

Found by: looking at warnings for comparing the result of lblktosize()
(which is usually daddr_t = long) with file sizes (which are u_quad_t
for ufs).  File sizes should probably be off_t's to avoid warnings
when the are compared with file offsets, so the fixed lblktosize()
casts to off_t instead of u_quad_t.

Added definition of smalllblksize().  It is the same as the old
lblksize() and is more efficient for small block numbers on 32-bit
machines.

Use smalllblktosize() instead of its expansion in blksize() and
dblksize().  This keeps the line length short and makes it more
obvious that the shift can't overflow.
