* Implement Proxy.revocable() and add test case coverage for some Proxy revocation basics. * Fix revoked Proxy handling in instanceof and Array.isArray(), and add test coverage. * Fix revoked Proxy handling in call setup, and add test coverage. Chained Proxies still not supported in call handling. * Add stack top asserts for internal duk_prop_xxx.c file APIs: defown, delete, enum, get, getown, has, ownpropkeys, set. * Fix unused duk_hobject layouts from property table init code in src-tools.pull/2487/head
