Robert Habermeier 64cec5ff7d Implement PIP messages, request builder, and handlers (#4945)
* return errors on database corruption

* fix tests, json tests

* fix remainder of build

* buffer flow -> request credits

* proving state backend

* generate transaction proofs from provider

* network messages for transaction proof

* transaction proof test

* test for transaction proof message

* fix call bug

* request transaction proofs from on_demand

* most of proved_execution rpc

* proved execution future

* initial request definitions

* RLP encoding and decoding for requests

* proofs of non-existance in ProvingBlockChainClient

* new requests in provider.

* encode and decode responses

* complete initial request changes

* handle request packet in LightProtocol

* handle response packets

* implement requesting from

* re-do cost table

* get tests compiling

* fix cost table RLP encoding

* roundtrip tests for request types

* request builder tests

* move request_builder -> request::builder

* get network tests working

* return only complete headers responses

* request builder improvements

* New version of jsonrpc.

* split request filling into fill,complete

* Better invalid encoding messages

* Fixing deprecated methods of tokio_core

* use PIP messages in on_demand, old API

* migrate oneshot::complete to send in on_demand

* get on_demand tests to compile

* port ethsync to PIP messages

* adjust to minor on_demand API changes in RPC

* Using dedicated branch for jsonrpc

* Bump

//! Light client logic and implementation.
//!
//! A "light" client stores very little chain-related data locally
//! unlike a full node, which stores all blocks, headers, receipts, and more.
//!
//! This enables the client to have a much lower resource footprint in
//! exchange for the cost of having to ask the network for state data
//! while responding to queries. This makes a light client unsuitable for
//! low-latency applications, but perfectly suitable for simple everyday
//! use-cases like sending transactions from a personal account.
//!
//! The light client performs a header-only sync, doing verification and pruning
//! historical blocks. Upon pruning, batches of 2048 blocks have a number => (hash, TD)
//! mapping sealed into "canonical hash tries" which can later be used to verify
//! historical block queries from peers.
