blockmanager.go: use btcd libs to validate headers #263

Closed Crypt-iQ closed 1 year ago

Crypt-iQ commented 1 year ago

This uses btcd's HeaderCtx and ChainCtx interfaces to be able to validate headers, both contextually and context-free. This allows neutrino to call blockchain.CheckBlockHeaderContext and blockchain.CheckBlockHeaderSanity. Also included is a check to assert that when neutrino receives a p2p headers message, that each header connects to the previous one.
