Service Node Deregister Part 5 (#89) * Retrieve quorum list from height, reviewed * Setup data structures for de/register TX * Submit and validate partial/full deregisters * Add P2P relaying of partial deregistration votes * Code review adjustments for deregistration part 1 - Fix check_tx_semantic - Remove signature_pod as votes are now stored as blobs. Serialization overrides don't intefere with crypto::signature anymore. * deregistration_vote_pool - changed sign/verify interface and removed repeated code * Misc review, fix sign/verify api, vote threshold * Deregister/tx edge case handling for combinatoric votes * core, service_node_list: separated address from service node pubkey * Retrieve quorum list from height, reviewed * Setup data structures for de/register TX * Submit and validate partial/full deregisters * Add P2P relaying of partial deregistration votes * Code review adjustments for deregistration part 1 - Fix check_tx_semantic - Remove signature_pod as votes are now stored as blobs. Serialization overrides don't intefere with crypto::signature anymore. * deregistration_vote_pool - changed sign/verify interface and removed repeated code * Misc review, fix sign/verify api, vote threshold * Deregister/tx edge case handling for combinatoric votes * Store service node lists for the duration of deregister lifetimes * Quorum min/max bug, sort node list, fix node to test list * Change quorum to store acc pub address, fix oob bug * Code review for expiring votes, acc keys to pub_key, improve err msgs * Add early out for is_deregistration_tx and protect against quorum changes * Remove debug code, fix segfault * Remove irrelevant check for tx v3 in blockchain, fix >= height for pruning quorum states Incorrect assumption that a transaction can be kept in the chain if it could eventually become invalid, because if it were the chain would be split and eventually these transaction would be dropped. But also that we should not override the pre-existing logic which handles this case anyway.
