electrod: cryptoverify transactions #27

Merkle tree validation for transactions

Handle 2 cases:

Do I have the tx in storage? It's verified.
No? Obtain transaction. Ask a remote merkle proof from the electrum network and validate with the local headers.

(We don't have yet inclusion blocks for transactions, need PR https://github.com/kyuupichan/electrumx/pull/397 to spread across servers to avoid too much errors, maybe Q2 2018).

Another option may be to push a bloom filter on the P2P net with the scripts involved in the transaction to obtain the related blocks. This also reduces the dependency from the electrum network.

transactions are crypto verified and then stored into a volatile sessionscoped dictionary.
