1. Change function name in BlockValidator interface from: "ValidateProofOfWorkAndDifficulty" to "ValidatePruningPointViolationAndProofOfWorkAndDifficulty".
2. Add to the blockValidator struct the pruningManager (also added to the function "New" Respectively).
3. Added new function "checkPruningPointViolation" of blockValidator type.
4. Add new internal check - "checkPruningPointViolation", on the function "ValidateProofOfWorkAndDifficulty".(The third check).
5. Add new error rule - "ErrPruningPointViolation".
* [Issue-1126]
1. Remove the function "PruningPoint" from PruningManager interface.
2. Changes in blockValidator struct - remove pruningManager, and adding pruningStore.
3. Reads for "pruningPoint" function from pruningStore instead of pruningManager (because of note 1 above) in the functions: * "checkPruningPointViolation" of type blockValidator.
* "FindNextPruningPoint" of type pruningManager.
* [Issue-1126]
1. Add missing error handling.
* [Issue-1126] Changes in function "checkPruningPointViolation": If header = genesis, stop checking and return nil.
* [Issue-1126] In function "checkPruningPointViolation" - change from a for loop to the "IsAncestorOfAny" function.
* [#1126] "FindNextPruningPoint" - save the pruning point in case the point is the genesis and change code internal order.
* [#1126] "FindNextPruningPoint" - cosmetics change.
* [#1126] "FindNextPruningPoint" - remove "return nil" when there is no pruning point on the if expression.
