    Paul Eggert authored
    * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
    (esprintf, esnprintf, exprintf, evxprintf): New functions.
    * keyboard.c (command_loop_level): Now EMACS_INT, not int.
    (cmd_error): kbd macro iterations count is now EMACS_INT, not int.
    (modify_event_symbol): Do not assume that the length of
    name_alist_or_stem is safe to alloca and fits in int.
    (Fexecute_extended_command): Likewise for function name and binding.
    (Frecursion_depth): Wrap around reliably on integer overflow.
    * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
    since some callers pass EMACS_INT values.
    (Fsingle_key_description): Don't crash if symbol name contains more
    than MAX_ALLOCA bytes.
    * minibuf.c (minibuf_level): Now EMACS_INT, not int.
    (get_minibuffer): Arg is now EMACS_INT, not int.
    * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
    (esprintf, esnprintf, exprintf, evxprintf): New decls.
    * window.h (command_loop_level, minibuf_level): Reflect API changes.
