[tor-commits] [sbws/master] fix: v3bwfile: Add tor_version KeyValue



commit 6843145a2887fb2496a2b5cef30ffabae2402cda
Author: juga0 <juga@xxxxxxxxxx>
Date:   Sun Feb 9 17:03:13 2020 +0000

    fix: v3bwfile: Add tor_version KeyValue
    
    - Create new KeyValues constants for the new v1.5.0 KeyValues
    - Instanciate State in Header.from_results so that there is no need
      to create new methods for all the header KeyValues that are read
      from the state file
    - Add tor_version to the kwargs to initialize the Header
    - Write tor_version in the state file when the scanner is started
    
    Closes: #30196.
