Implement pruning point proof (#1832)
* Calculate GHOSTDAG, reachability etc for each level

* Don't preallocate cache for dag stores except level 0 and reduce the number of connections in the integration test to 32

* Reduce the number of connections in the integration test to 16

* Increase page file

* BuildPruningPointProof

* BuildPruningPointProof

* Add PruningProofManager

* Implement ApplyPruningPointProof

* Add prefix and fix blockAtDepth and fill headersByLevel

* Some bug fixes

* Include all relevant blocks for each level in the proof

* Fix syncAndValidatePruningPointProof to return the right block hash

* Fix block window

* Fix isAncestorOfPruningPoint

* Ban for rule errors on pruning proof

* Find common ancestor for blockAtDepthMAtNextLevel

* Use pruning proof in TestValidateAndInsertImportedPruningPoint

* stage status and finality point for proof blocks

* Uncomment golint

* Change test timeouts

* Calculate merge set for ApplyPruningPointProof

* Increase test timeout

* Add better caching for daa window store

* Return to default timeout

* Add ErrPruningProofMissesBlocksBelowPruningPoint

* Add errDAAWindowBlockNotFound

* Force connection loop next iteration on connection manager stop

* Revert to Test64IncomingConnections

* Remove BlockAtDepth from DAGTraversalManager

* numBullies->16

* Set page file size to 8gb

* Increase p2p max message size

* Test64IncomingConnections->Test16IncomingConnections

* Add comment for PruningProofM

* Add comment in `func (c *ConnectionManager) Stop()`

* Rename isAncestorOfPruningPoint->isAncestorOfSelectedTip

* Revert page file to 16gb

* Improve ExpectedHeaderPruningPoint perf

* Fix comment

* Revert "Improve ExpectedHeaderPruningPoint perf"

This reverts commit bca1080e7140c78d510f51bbea858ae280c2f38e.

* Don't test windows
