blockchain: Add ReconsiderBlock to BlockChain

ReconsiderBlock reconsiders the validity of the block for the passed
in blockhash. The behavior of the function mimics that of Bitcoin Core.

The invalid status of the block nodes are reset and if the chaintip that
is being reconsidered has more cumulative work, then we'll validate the
blocks and reorganize to it. If the cumulative work is lesser than the
current active chain tip, then nothing else will be done.
