    Tidy handling of pluto_log_file
    - don't open pluto_log_file if it is NULL
    - add missing newline after diagnostic for failure to open pluto_log_file
    - rename pluto_log_fd to pluto_log_fp (it is a FILE *, not a file descriptor)
    - protect against use of pluto_log_fp after fclose
    - simplify by eliminating log_to_file
    - improve modularity of log.c
