I pushed a definition of the new data structures, plus two predefined
print context kinds, to the new "print-context" branch:


The new functionality is not yet used from the rest of the code base,
but it will soon.  I have tested it with dirty code which is not worth
committing to git.  Example:

  jitter_print_context cx = jitter_print_context_make_file_star (stdout);
  jitter_print_char_star (cx, "===========\n");
  jitter_print_pointer (cx, main);
  jitter_print_char_star (cx, "\n===========\n");
  jitter_print_int (cx, 10, 0); jitter_print_char_star (cx, "\n");
  jitter_print_begin_class (cx, "interesting");
  jitter_print_int (cx, 2, 14); jitter_print_char_star (cx, "\n");
  jitter_print_end_class (cx);
  jitter_print_int (cx, 10, 1234567); jitter_print_char_star (cx, "\n");
  jitter_print_ulong_long (cx, 10, 1234567); jitter_print_char_star (cx, "\n");
  jitter_print_long_long (cx, 10, -123456789012345LL); jitter_print_char_star 
(cx, "\n");
  jitter_print_destroy_context (cx);

I welcome comments.
