parser: no string allocation when scanning floats.
Each time the scanner processes a floating-point token,
it allocates a string object, just so it can call flo_str.
The object is then garbage. Let's stop doing that.
* lib.c (flo_str_utf8): New function, closely based on flo_str.
Takes a char * string.
* lib.h (flo_str_utf8): Declared.
* parser.l (out_of_range_float): Take the token as a const
char * string instead of a Lisp string, so we can just pass
yytext to this function.
(grammar): Use flo_str_utf8 instead flo_str, and pass yytext
to out_of_range_float.
* lex.yy.c.shipped: Updated.
