      Even though this function is called initlog(), you should always
      use log(); log is a variable that is set either to initlog
      (initially), to dolog (once the log file has been opened), or to
      nolog (when logging is disabled).
  
      The first argument is a format string; the remaining arguments (if
      any) are arguments to the % operator, so e.g.
          log("%s: %s", "a", "b")
      will write "a: b" to the log file, followed by a newline.
  
      If the global logfp is not None, it should be a file object to
      which log data is written.
  
      If the global logfp is None, the global logfile may be a string
      giving a filename to open, in append mode.  This file should be
      world writable!!!  If the file can't be opened, logging is
      silently disabled (since there is no safe place where we could
      send an error message).
