* need to use new APIs available in v8
* check new API for external heap tracing

refactored sethiddenvalue/gethiddenvalue to use one method
fixed setWeak call to use weakcallbackinfo instead of weakcallbackdata
passed additional parameter to setWeak (revisit logic there k::parameter)
wip (project compiles with ndk r11c)

the v8::ObjectTemplate->Set api now takes functionTemplate instead of func as parameter

* got most of the tests running by changing WeakCallbackType from ::kParameter to ::kFinalizer
* the tests still failing are in:
(still need to research the difference between WeakCallbackType options)

refactor setting of static metadata members to set fields and set methods separately
set field accessors before creating the function's prototype object (we need to be sure we don't try to modify the PrototypeTemplate after the prototype object is created or it will not take effect on the created object)

… we can determine the bitness of the current process
