Here is the change that reverts most of the modifications and disables 
cloning new blocks. It does retain ability to free existing cloned 
blocks and keeps block_cloning feature around, so upgraded pools can be 
imported and existing cloned blocks freed.

It does not handle replaying ZIL with block-cloning logs, so make sure 
you import pools that were cleanly exported.

I'd appreciate if someone who can reproduce those corruptions could try it.
