This check was performed for both the reorg and non-reorg cases, but in the reorg case the headers would count for PoW before validating that the headers connected to one another.
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.

Replaces #263.
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.
Fixes #255
