hgweb: compatibility of hgweb.cgi template with Python 3 When running Mercurial on Python 3 hgweb expects the config variable to be a bytestring. The solution proposed by Anton Shestakov is to use a byteprefix to the literal string defined cgi script as provided in this patch for hgweb.cgi, contrib/hgweb.fcgi and contrib/hgweb.wsgi. I am not sure whether this covers all relevant templates, but I couldn't find others. Differential Revision: https://phab.mercurial-scm.org/D8978
