* Refactor updater to use ethabi-derive * Grumble: do_call type alias * Empty commit to trigger test re-run * migration to ethabi-5.0 * migration to ethabi-5.0 in progress * use ethabi_deriven to generate TransactAcl contract * use ethabi_deriven to generate Registry contract * hash-fetch uses ethabi_derive, removed retain cycle from updater, fixed #7720 * node-filter crate uses ethabi_derive to generate peer_set contract interface * use LruCache in node-filter instead of HashMap * validator_set engine uses ethabi_derive * ethcore does not depend on native_contracts * miner does no depend on native_contracts * secret_store does not use native_contracts (in progress) * removed native-contracts * ethcore and updater does not depend on futures * updated ethereum-types * fixed all warnings caused by using new version of ethereum-types * updated ethabi_derive && ethabi_contract to get rid of warnings * removed another retain cycle in updater, fixed following minor version on update * moved contracts out of native_contracts res * updated ethabi_contract * fixed failing test * fixed failing test * there is no need to create two contracts of the same kind any more * simplify updater::ReleaseTrack conversion into u8 and add several tests for it * applied review suggestions * applied review suggestions
