Support collecting root block coinbase in other native tokens

7

which is not supported right now (using hard-coded genesis token): https://github.com/QuarkChain/pyquarkchain/blob/c3a76bc0527387a606b87a87b0706b929d88c95b/quarkchain/cluster/shard_state.py#L94-L123 that's why even [this root block](http://testnet2.quarkchain.io/block/36614) has QTSLA token in coinbase (which comes from tx fee), the root block...

ShardState.__validate_tx should not depend on shard state non-constant variable

slaves should be able to directly connect peers instead of going through the proxy connection in master. specially, now master handles message encryption/decryption and has to perform on all shards...

improve devp2p TCP sockets tracking

1

a lot of things can go wrong when establishing p2p connections: failed handshake, wrong version, mismatching serialization, we shall ensure all opened TCP sockets are closed properly

One of the issues that QuarkChain team noticed during testnet 2.0 is incompatible network id issues when a new network is being started (while there are some clusters running the...
