Block Sync Improvements

  As the chain height rises gradually, the synchronization duration increases linearly. This PR is the beginning of improving the synchronization time.

• #1966: Enhanced locator (@driftluo)

  After allowing ibd multi-node download, the premise of enabling multi-node download is to update the best-known header of the corresponding node as soon as possible.

Features

• #1848: Add a new json rpc method get_block_economic_state (@yangby-cryptape)

• #1915: Reject new scripts with known bugs (@xxuejie)

  For compatibility reasons, there're certain bugs that we have to leave
  to the next hardfork to fix. However those bugs, especially VM bugs
  might lead to surprising unexpected behaviors. This change adds a new
  checker that checks against newly created cells for scripts with bugs,
  and reject those transaction when we can. This way we can alert users
  about the bugs as early as we can.
