DEFVAR_INT variables are now intmax_t

Formerly they were fixnums, which led to problems when dealing
with values that might not fit on 32-bit platforms, such as
string-chars-consed or floats_consed.  64-bit counters should
be good enough for these (for a while, anyway...).
While we’re at it, fix some unlikely integer overflow bugs
that have been in the code for a while.

DEFVAR_INT variables now have the C type intmax_t, not EMACS_INT.

* src/gnutls.c (Fgnutls_boot):
* src/keyboard.c (bind_polling_period):
* src/macros.c (pop_kbd_macro, Fexecute_kbd_macro):
* src/undo.c (truncate_undo_list):
Allow any integer that fits into intmax_t, instead of
requiring it to be a Lisp fixnum.

Avoid implementation-defined behavior on conversion of
out-of-range integers.
* src/eval.c (when_entered_debugger): Now intmax_t.
(max_ensure_room): New function, that avoids signed integer overflow.
(call_debugger, signal_or_quit): Use it.

Avoid signed integer overflow.
* src/lisp.h (clip_to_bounds): Generalize to intmax_t.
* src/pdumper.c (dump_emacs_reloc_immediate_emacs_int): Remove, ...
(dump_emacs_reloc_immediate_intmax_t): ... replacing with this
function.  All uses changed.
* src/profiler.c (make_log): Omit args.  All callers changed.
* src/termcap.c: Include stdlib.h, for atoi.
Include intprops.h.
* src/window.c (sanitize_next_screen_context_lines): New function.
(window_scroll_pixel_based, window_scroll_line_based):
Use it to avoid signed integer overflow.
