Update to version 5.7.0
Duktape is an embeddable Javascript engine, with a focus on portability and
compact footprint.

Duktape is easy to integrate into a C/C++ project: add duktape.c and duktape.h
to your build, and use the Duktape API to call Ecmascript functions from C code
and vice versa.

Main features:

  * Embeddable, portable, compact; about 210kB code, 80kB memory, 40kLoC source
(excluding comments etc)
  * Ecmascript E5/E5.1 compliant, some features borrowed
    from E6 draft
  * Built-in regular expression engine
  * Built-in Unicode support
  * Minimal platform dependencies
  * Combined reference counting and mark-and-sweep garbage collection with
    finalization
  * Custom features like coroutines, built-in logging framework, and built-in
    CommonJS-based module loading framework
  * Property virtualization using a subset of Ecmascript E6 Proxy object
  * Liberal license (MIT)
