dlmalloc has been removed and the NDK now exposes a malloc.h header with
malloc_usable_size exposed, so use that.
Also remove the duplication in js__malloc_usable_size.

* Improve error handling
- throw RangeError for invalid string length
- throw RangeError for stack overflow with updated message
- fix case for `BigInt` error messages
- refine stack check for `next_token` and `json_next_token`
- throw SyntaxError for too many variables, arguments, parameters...
- v8.js: disable v8 specific tests
- v8.js: disable Realm object tests
- v8.js: disable MODULE tests
- v8.js: disable RegExp static properties tests
- use more precise error messages
- reorder property lookup in `js_obj_to_desc()` according to ECMA
- set global object's [Symbol.toStringTag] to "global"
- fix error message for duplicate parameter name in strict mode
* Improve `Date.parse()`
- rewrite `Date.parse()` with separate parsers
- return `NaN` for out of bounds field values as specified
- add `js_tzabbr` and `string_get_tzabbr` to handle timezone abbreviations
- improve `string_get_milliseconds` readability
- accept up to 9 decimals for millisecond fraction but truncate at 3
- accept many more alternative date/time formats
- add test cases in **tests/test_builtin.js**
- produce readable output for `Date` objects in repl
- use `JSON.stringify` to output `Date` and `string` values in **repl.js**
- remove `String.prototype.__quote`
- add `minimum_length` macro to specify argument array sizes (C99 except MSVC)
- v8.js: parse all environment variables and output them, update **v8.txt**
* Fix bug in `GET_PREV_CHAR` macro
- pass `cbuf_type` variable to `XXX_CHAR` macros in `lre_exec_backtrack()`
- improve readability of these macros
- fix `GET_PREV_CHAR` macro: `cptr` was decremented twice on invalid high surrogate.
- minimize non functional changes
* Fix big endian serialization
Big endian serialization was broken because:
- it partially relied on `WORDS_ENDIAN` (unconditionally undef'd in cutils.h)
- endianness was not handled at all in the bc reader.
- `bc_tag_str` was missing the `"RegExp"` string
- `lre_byte_swap()` was broken for `REOP_range` and `REOP_range32`
Modifications:
- remove `WORDS_ENDIAN`
- use `bc_put_u32()` / `bc_put_u64()` in `JS_WriteBigInt()`
- use `bc_get_u32()` / `bc_get_u64()` in `JS_ReadBigInt()`
- handle host endianness in `bc_get_u16()`, `bc_get_u32()`, `bc_get_u64()` and
`JS_ReadFunctionBytecode()`
- handle optional littleEndian argument as specified in
`js_dataview_getValue()` and `js_dataview_setValue()`
- fix `bc_tag_str` and `lre_byte_swap()`
The non-Unicode version of the pattern was already accepted.
test262 tests it in an inverted sense in
test/built-ins/RegExp/unicode_restricted_identity_escape.js but
it appears to be per spec and both V8 and Spidermonkey accept it.

- fix the conversions for integers and exact fractions
- approximate approach for other cases.
- bypass floating point conversions for JS_TAG_INT values
- avoid divisions for base 10 integer conversions

I have a use case where a user can hand me many different kinds of
types, array buffer, uint8array, or a string, and I need to be able to
distingush between them.

* Add method to GetClassID
If you want to extend a built-in class you need it's class ID and there
is no robust way to get that without this accessor.

`ToString(object)` can fail when there is a pending exception. Add a
special case for exception objects to help debugging. Getting an empty
string when the real error was "InternalError: stack overflow" is rage
inducing.

There was no definition of the macro for compilers that were not gcc,
clang or msvc. While it would be easy to add one, a better approach is
to switch to memcpy() and avoid type punning altogether.
