This patch adds plumbing to support the implementations of StackFrame::Get{*}Variable{*} on ScriptedFrame. The major pieces required are:
- A modification to ScriptedFrameInterface, so that we can actually call the python methods.
- A corresponding update to the python implementation to call the python methods.
- An implementation in ScriptedFrame that can get the variable list on construction inside ScriptedFrame::Create, and pass that list into the ScriptedFrame so it can get those values on request.
There is a major caveat, which is that if the values from the python side don't have variables attached, right now, they won't be passed into the scripted frame to be stored in the variable list. Future discussions around adding support for 'extended variables' when printing frame variables may create a reason to change the VariableListSP into a ValueObjectListSP, and generate the VariableListSP on the fly, but that should be addressed at a later time.
This patch also adds tests to the frame provider test suite to prove these changes all plumb together correctly.
