zil: Add some more statistics.
In addition to a number of actual log bytes written, account also a
total written bytes including padding and total allocated bytes (bytes
<= write <= alloc). It should allow to monitor zil traffic and space
efficiency.
Add dtrace probe for zil block size selection.
Make zilstat report more information and fit it into less width.
