Prefer now-standard int width macros

* src/data.c (ULL_WIDTH):
* src/lisp.h (EMACS_INT_WIDTH, BITS_PER_BITS_WORD):
* src/lread.c (read_integer):
* src/term.c (produce_glyphless_glyph):
* src/xterm.c (x_send_scroll_bar_event):
Use *_WIDTH macros instead of CHAR_BIT * sizeof.
* src/data.c (ULL_WIDTH): Rename from BITS_PER_ULL for consistency
with the *_WIDTH standard macros.  All uses changed.
* src/gmalloc.c (INT_BIT): Remove.  All uses replaced with INT_WIDTH.
* src/lisp.h (EMACS_INT_WIDTH): Rename from BITS_PER_EMACS_INT
for consistency with the *_WIDTH standard macros.  All uses changed.
(BITS_PER_CHAR): Remove; all uses replaced by CHAR_BIT.  This must
be the same as CHAR_WIDTH and avoids confusion with Elisp
char-width, which counts columns not bits.
(BITS_PER_SHORT): Remove; all uses replaced by SHRT_WIDTH.
(BITS_PER_LONG): Remove; all uses replaced by LONG_WIDTH.
* src/lread.c: Do not include limits.h since CHAR_BIT is no longer
used directly.
