A missing piece for transitioning from legacy bootstrap to full ascending bootstrap was a missing frontier query. This query is needed for efficient (bulk) scanning of accounts for updates. Currently we are forced to do a request - reply for every single account that we want to check for changes. This PR adds a new payload type for ascending bootstrap messages and support for serving those requests in bootstrap_server.

  • frontier request:

    • start: account (0 for starting from beginning)
    • count: uint16_t (bounded to 1000 due to 65kb size limit of a single message)
  • frontier response:

    • frontiers: <account, block hash> list

This also bumps the current protocol version to 20, keeping compatibility with previous versions as is.
