    Use sprintf return value instead of invoking strlen on result. · 99027bdd

    In the old days this wasn't portable, since some sprintf
    implementations returned char *.  But they died out years ago and
    Emacs already assumes sprintf returns int.
    Similarly for float_to_string.
    This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
    * ccl.c (ccl_driver):
    * character.c (string_escape_byte8):
    * data.c (Fnumber_to_string):
    * doprnt.c (doprnt):
    * print.c (print_object):
    * xdisp.c (message_dolog):
    * xfns.c (syms_of_xfns):
    Use sprintf or float_to_string result to avoid need to call strlen.
    * data.c (Fnumber_to_string):
    Use make_unibyte_string, since the string must be ASCII.
    * lisp.h, print.c (float_to_string): Now returns int length.
    * term.c (produce_glyphless_glyph):
    Use sprintf result rather than recomputing it.
