This PR will add new blcok fetching mechanism, it will reduce the block fetching time cost a lot.
Motivation
With the future activation of BEP-520 and BEP-524, BSC will achieve a subsecond block interval, which has higher requirements for faster block fetching.
However, the eth/68 protocol is very inefficient when processing NewBlockHash messages, and it requires multiple queries before a new block can be imported.
Summary
This BEP introduces a New Block Fetching Message, which greatly reduces the number of queries, supports fast fetching of newly generated blocks, avoids validators and full nodes from lagging behind in the subsecond block interval, and especially improves the validator consensus efficiency, which can produce the next block or send vote faster.
