New headers first flow (#1211)

Browse Source 
* Get rid of insertMode

* Rename AddBlockToVirtual->AddBlock

* When F is not in the future of P, enforce finality with P and not with F.

* Don't allow blocks with invalid parents or with missing block body

* Check finality violation before checking block status

* Implement CalculateIndependentPruningPoint

* Move checkBlockStatus to validateBlock

* Add ValidateBlock to block processor interface

* Adjust SetPruningPoint to the new IBD flow

* Add pruning store to CSM's constructor

* Flip wrong condition on AddHeaderTip

* Fix func (hts *headerSelectedTipStore) Has

* Fix block stage order

* Call to ValidateBodyInContext from validatePostProofOfWork

* Enable overrideDAGParams

* Update log

* Rename SetPruningPoint to ValidateAndInsertPruningPoint and move most of its logic inside block processor

* Rename hasValidatedHeader->hasValidatedOnlyHeader

* Fix typo

* Name return values for fetchMissingUTXOSet

* Add comment

* Return ErrMissingParents when block body is missing

* Add logs and comments

* Fix merge error

* Fix pruning point calculation to be by virtual selected parent

* Replace CalculateIndependentPruningPoint to CalculatePruningPointByHeaderSelectedTip

* Fix isAwaitingUTXOSet to check pruning point by headers

* Change isAwaitingUTXOSet indication

* Remove IsBlockInHeaderPruningPointFuture from BlockInfo

* Fix LowestChainBlockAboveOrEqualToBlueScore

* Add validateNewPruningPointTransactions

* Add validateNewPruningAgainstPastUTXO

* Rename set_pruning_utxo_set.go to update_pruning_utxo_set.go

* Check missing block body hashes by missing block instead of status

* Validate pruning point against past UTXO with the pruning point as block hash

* Remove virtualHeaderHash

* Fix comment

* Fix imports
