Perhaps lua_tostring should access the string without conversion (or perhaps
lua_rawtostring) while luaL_tostring would invoke the same logic as the Lua
tostring function (and probably change the stack slot along the way).

Are there really that many cases where it is useful to convert numbers to
strings without converting other types? I would love, for example, to have a
character in string.format's format string that would mean "run the argument
through tostring".
