- add `js_snprintf`, `js_printf`... to handle extra conversions: - support for wxx length modifier - support for `%b` and `%B` - `%oa` and `%#oa` to convert `JSAtom` values - `%ps` to convert `JSString` values - add `dbuf_vprintf_fun` replaceable `dbuf_printf` handler - change `JS_DumpString` to `JS_FormatString` to convert `JSSAtom` to quoted strings - change `JS_AtomGetStrRT` to `JS_FormatAtom` to convert `JSAtom` to strings - change `JS_AtomGetStr` to return direct string pointer for builtin atoms - remove `print_atom` - use custom conversions for trace messages and error messages - add support for `%b`, `%B` and `w` length modifier in `std.printf` - remove error handlers: `JS_ThrowTypeErrorAtom` and `JS_ThrowSyntaxErrorAtom` - add `is_lower_ascii()` and `to_lower_ascii()` - add floating point conversions and wide string conversions - unbreak compilation: prevent name collision on pow10 - minimize `vsnprintf` calls in `dbuf_vprintf_default`
