    libipseconf: add explicit rules for <KEY>\n, <KEY>= and <VALUE>\n et.al.
    
    Add explicit KEY and BOOLEAN_KEY states.  Add explicit per-state rules
    to both eat blanks and match \n as EOL.
    
    This will stop the lexer's default rule eating the '\n' following '=':
      conn first
         rightsubnet=
      conn second
    causing it to return:
       CONN "first" KEY(rightsubnet) EQUAL CONN "second"
    when it should have returned:
       CONN "first" KEY(rightsubnet) EQUAL EOL CONN "second"
    
    This also fixes libipsecconf-05-empty_option to the point where
    addconn parses the config files the way parser.y intended.  The next
    problem is with parser.y which very deliberately allows the above
    blank rightsubnet= line but should it?
