Brian Behlendorf 2b0502c578 Add interface to interface spa_get_worst_case_min_alloc() function 
Provide an interface to retrieve the lowest and highest minimum
allocation size for the normal allocation class.  This can be used
by external consumers of the DMU to estimate potential wasted
capacity when setting the recordsize for an object.

The new "min_alloc" and "max_alloc" keys are added to the pool
configuration and used by default_volblocksize() to warn when
an ineffecient block size is requested.  For older kmods which
don't yet include the new keys fallback to the previous logic.
