    * Add params package with exported variables generated from
      github.com/ethereum/common/blob/master/params.json
    * Use params package variables in applicable places
    * Add check for minimum gas limit in validation of block's gas limit
    * Remove common/params.json from go-ethereum to avoid
      outdated version of it
