Refine split block reconstruction
Due to a flaw in 4589f3ae the number of unique combinations could be calculated incorrectly. This could result in the random combinations reconstruction being used when it would have been possible to check all combinations. This change fixes the unique combinations calculation and simplifies the reconstruction logic by maintaining a per- segment list of unique copies. The vdev_indirect_splits_damage() function was introduced to validate both the enumeration and random reconstruction logic with ztest. It is implemented such it will never make a known recoverable block unrecoverable.
