Lua 5.3 Changes

• new datatype integer
  0 is integer and 0.0 is double

- sprintf(ret, LUA_NUMBER_FMT, nvalue(o));

+ sprintf(ret, LUA_NUMBER_FMT, fltvalue(o));
+ sprintf(ret, LUA_INTEGER_FMT, ivalue(o));

• subtypes

/* Variant tags for strings */
#define LUA_TSHRSTR	(LUA_TSTRING | (0 << 4))  /* short strings */
#define LUA_TLNGSTR	(LUA_TSTRING | (1 << 4))  /* long strings */


/* Variant tags for numbers */
#define LUA_TNUMFLT	(LUA_TNUMBER | (0 << 4))  /* float numbers */
#define LUA_TNUMINT	(LUA_TNUMBER | (1 << 4))  /* integer numbers */

• TString format changed

#if LUA_VERSION_NUM == 501 || LUA_VERSION_NUM == 502
	#define rawtsvalue(o)	check_exp(ttisstring(o), &(o)->value.gc->ts)
	#define tsvalue(o)	(&rawtsvalue(o)->tsv)

	#define LUA_STRLEN(ts) ((ts)->tsv.len)
#endif
#if LUA_VERSION_NUM == 503
	#define tsvalue(o)	check_exp(ttisstring(o), gco2ts(val_(o).gc))

	#define rawtsvalue(o) tsvalue(o)
	#define LUA_STRLEN(ts) ((ts)->len)
#endif
