* add auto-args deserialization for RPC
* make block param member public
* change BlockParam to a more generic Trailing<T> mechanism
* define work type
* build_rpc_trait macro, implement eth protocol
* fix up tests
* move eth_filter API to new macro
* Making ConfirmationsQueue a bit more generic [WiP]
* Generalizing cofirmations
* New confirmations types - tests
* Separating transaction type in queue. Closes#1310
* Handling sign requests
* Speeding up tests
* Renaming methods
* eth_postSign
* Bumping ui
* Asynchronous transactions (polling based for now).
- Alter eth_sendTransaction to be async, returning one of:
- Transaction hash (signed and submitted).
- Transaction promise ID (< 32 bytes).
- Zero hash (will never be signed).
- Introduce new JSONRPC eth_checkTransaction.
The new API call takes a single argument - a promise ID. It returns
either:
- Transaction hash (signed and submitted).
- null (still pending, call again later),
- Zero hash (will never be signed).
* New RPC eth_postTransaction
- Restore previous semantics of sendTransaction.
- Introduce eth_postTransaction.
- Some refactoring.
* Fix minor lockup.
* Use TransientHashMap to prevent leak.
* removed old json-tests
* simplify folds in triehash.rs
* removed unused json_aid
* removed unused squeeze.rs
* json branching tests for trie
* removing todos from util
* separated UsingQueue and Table
* further cleanup, removing unused code
* serde serialization of hash moved to rpc module
* uint wrapper for rpc in progress
* serialization of uint moved to rpc module
* updated eth-secp256k1
* updated igd, serde is no longer dependency of util
* loading trie consensus tests
* renamed aliases in rpc imports
